The 2026 Data Availability Race: Celestia, EigenDA, and Avail's Battle for Blockchain Scalability

· 13 min read

Every Layer 2 you use relies on a hidden infrastructure most users never think about: data availability layers. But in 2026, this quiet battlefield has become the most critical piece of blockchain scalability, with three giants—Celestia, EigenDA, and Avail—racing to process terabits of rollup data per second. The winner doesn't just capture market share; they define which rollups survive, how much transactions cost, and whether blockchain can scale to billions of users.

The stakes couldn't be higher. Celestia commands roughly 50% of the data availability market after processing over 160 gigabytes of rollup data. Its upcoming Matcha upgrade in Q1 2026 will double block sizes to 128MB, while the experimental Fibre Blockspace protocol promises a staggering 1 terabit per second throughput—1,500 times their previous roadmap target. Meanwhile, EigenDA has achieved 100MB/s throughput using a Data Availability Committee model, and Avail has secured integrations with Arbitrum, Optimism, Polygon, StarkWare, and zkSync for its mainnet launch.

This isn't just infrastructure competition—it's a battle over the fundamental economics of Layer 2 networks. Choosing the wrong data availability layer can increase costs by 55 times, making the difference between a thriving rollup ecosystem and one strangled by data fees.

The Data Availability Bottleneck: Why This Layer Matters

To understand why data availability has become blockchain's most important battlefield, you need to grasp what rollups actually do. Layer 2 rollups like Arbitrum, Optimism, and Base execute transactions off-chain to achieve faster speeds and lower costs, then post transaction data somewhere secure so anyone can verify the chain's state. That "somewhere secure" is the data availability layer.

For years, Ethereum's mainnet served as the default DA layer. But as rollup usage exploded, Ethereum's limited block space created a bottleneck. Data availability fees spiked during periods of high demand, eating into the cost savings that made rollups attractive in the first place. The solution? Modular data availability layers purpose-built to handle massive throughput at minimal cost.

Data availability sampling (DAS) is the breakthrough technology enabling this transformation. Instead of requiring every node to download entire blocks to verify availability, DAS allows light nodes to probabilistically confirm data is available by sampling small random chunks. More light nodes sampling means the network can safely increase block sizes without sacrificing security.

Celestia pioneered this approach as the first modular data availability network, separating data ordering and availability from execution and settlement. The architecture is elegant: Celestia orders transaction data into "blobs" and guarantees their availability for a configurable period, while execution and settlement happen on layers above. This separation allows each layer to optimize for its specific function rather than compromising on all fronts like monolithic blockchains.

By mid-2025, more than 56 rollups were using Celestia, including 37 on mainnet and 19 on testnet. Eclipse alone has posted over 83 gigabytes through the network. Every major rollup framework—Arbitrum Orbit, OP Stack, Polygon CDK—now supports Celestia as a data availability option, creating switching costs and network effects that compound Celestia's early-mover advantage.

Celestia's Two-Pronged Attack: Matcha Upgrade and Fibre Blockspace

Celestia isn't resting on its market share. The project is executing a two-phase strategy to cement dominance: the near-term Matcha upgrade bringing production-ready scalability improvements, and the experimental Fibre Blockspace protocol targeting 1 terabit per second of future throughput.

Matcha Upgrade: Doubling Down on Production Scale

The Matcha upgrade (Celestia v6) is currently live on the Arabica testnet with mainnet deployment expected in Q1 2026. It represents the largest single capacity increase in Celestia's history.

Core improvements include:

  • 128MB block size: CIP-38 introduces a new high-throughput block propagation mechanism, increasing maximum block size from 8MB to 128MB—a 16x jump. The data square size expands from 128 to 512, and maximum transaction size grows from 2MB to 8MB.

  • Reduced storage requirements: CIP-34 cuts Celestia's minimum data pruning window from 30 days to 7 days plus 1 hour, slashing storage costs for bridge nodes from 30TB to 7TB at projected throughput levels. For rollups running high-volume applications, this storage reduction translates directly to lower operational costs.

  • Light node optimization: CIP-35 introduces pruning for Celestia light nodes, allowing them to retain only recent headers rather than the entire chain history. Light node storage requirements drop to approximately 10GB, making it feasible to run verification nodes on consumer hardware and mobile devices.

  • Inflation cut and interoperability: Beyond scalability, Matcha cuts protocol inflation from 5% to 2.5%, potentially making TIA deflationary if network usage grows. It also removes the token filter for IBC and Hyperlane, positioning Celestia as a routing layer for any asset across multiple ecosystems.

In testing environments, Celestia achieved approximately 27 MB/s throughput with 88 MB blocks in the Mammoth Mini devnet, and 21.33 MB/s sustained throughput with 128 MB blocks in the mamo-1 testnet. These aren't theoretical maximums—they're production-proven benchmarks that rollups can rely on when architecting for scale.

Fibre Blockspace: The 1 Tb/s Future

While Matcha focuses on near-term production readiness, Fibre Blockspace represents Celestia's moonshot vision for blockchain throughput. The protocol is capable of sustaining 1 terabit per second of blockspace across 500 nodes—a throughput level 1,500 times the goal set in Celestia's previous roadmap.

The core innovation is ZODA, a new encoding protocol that Celestia claims processes data 881 times faster than KZG commitment-based alternatives used by competing DA protocols. During large-scale network tests using 498 GCP machines distributed across North America (each with 48-64 vCPUs, 90-128GB RAM, and 34-45Gbps network links), the team successfully demonstrated terabit-scale throughput.

Fibre targets power users with a minimum blob size of 256KB and maximum of 128MB, optimized for high-volume rollups and institutional applications requiring guaranteed throughput. The rollout plan is incremental: Fibre will first deploy to the Arabica testnet for developer experimentation, then graduate to mainnet with progressive throughput increases as the protocol undergoes real-world stress testing.

What does 1 Tb/s actually mean in practice? At that throughput level, Celestia could theoretically handle the data needs of thousands of high-activity rollups simultaneously, supporting everything from high-frequency trading venues to real-time gaming worlds to AI model training coordination—all without the data availability layer becoming a bottleneck.

EigenDA and Avail: Different Philosophies, Different Trade-offs

While Celestia dominates market share, EigenDA and Avail are carving out distinct positioning with alternative architectural approaches that appeal to different use cases.

EigenDA: Speed Through Restaking

EigenDA, built by the EigenLayer team, has released V2 software achieving 100MB per second throughput—significantly higher than Celestia's current mainnet performance. The protocol leverages EigenLayer's restaking infrastructure, where Ethereum validators reuse their staked ETH to secure additional services including data availability.

The key architectural difference: EigenDA operates as a Data Availability Committee (DAC) rather than a publicly verified blockchain. This design choice removes certain verification requirements that blockchain-based solutions implement, enabling DACs like EigenDA to reach higher raw throughput while introducing trust assumptions that validators in the committee will honestly attest to data availability.

For Ethereum-native projects prioritizing seamless integration with the Ethereum ecosystem and willing to accept DAC trust assumptions, EigenDA offers a compelling value proposition. The shared security model with Ethereum mainnet creates a natural alignment for rollups already relying on Ethereum for settlement. However, this same dependency becomes a limitation for projects seeking sovereignty beyond the Ethereum ecosystem or requiring the strongest possible data availability guarantees.

Avail: Multichain Flexibility

Avail launched its mainnet in 2025 with a different focus: optimizing data availability for highly scalable and customizable rollups across multiple ecosystems, not just Ethereum. The protocol combines validity proofs, data availability sampling, and erasure coding with KZG polynomial commitments to deliver what the team calls "world-class data availability guarantees."

Avail's current mainnet throughput stands at 4MB per block, with benchmarks demonstrating successful increases to 128MB per block—a 32x improvement—without sacrificing network liveness or block propagation speed. The roadmap includes progressive throughput increases as the network matures.

The project's major achievement in 2026 has been securing integration commitments from five major Layer 2 projects: Arbitrum, Optimism, Polygon, StarkWare, and zkSync. Avail claims over 70 partnerships total, spanning application-specific blockchains, DeFi protocols, and Web3 gaming chains. This ecosystem breadth positions Avail as the data availability layer for multichain infrastructure that needs to coordinate across different settlement environments.

Avail DA represents the first component of a three-part architecture. The team is developing Nexus (an interoperability layer) and Fusion (a security network layer) to create a full-stack modular infrastructure. This vertical integration strategy mirrors Celestia's vision of being more than just data availability—becoming fundamental infrastructure for the entire modular stack.

Market Position and Adoption: Who's Winning in 2026?

The data availability market in 2026 is shaping up as a "winner takes most" dynamic, with Celestia holding commanding early-stage market share but facing credible competition from EigenDA and Avail in specific niches.

Celestia's Market Dominance:

  • ~50% market share in data availability services
  • 160+ gigabytes of rollup data processed through the network
  • 56+ rollups using the platform (37 mainnet, 19 testnet)
  • Universal rollup framework support: Arbitrum Orbit, OP Stack, and Polygon CDK all integrate Celestia as a DA option

This adoption creates powerful network effects. As more rollups choose Celestia, developer tooling, documentation, and ecosystem expertise concentrate around the platform.

Switching costs increase as teams build Celestia-specific optimizations into their rollup architecture. The result is a flywheel where market share begets more market share.

EigenDA's Ethereum Alignment:

EigenDA's strength lies in its tight integration with Ethereum's restaking ecosystem. For projects already committed to Ethereum for settlement and security, adding EigenDA as a data availability layer creates a vertically integrated stack entirely within the Ethereum universe.

The 100MB/s throughput also positions EigenDA well for high-frequency applications willing to accept DAC trust assumptions in exchange for raw speed.

However, EigenDA's reliance on Ethereum validators limits its appeal for rollups seeking sovereignty or multichain flexibility. Projects building on Solana, Cosmos, or other non-EVM ecosystems have little incentive to depend on Ethereum restaking for data availability.

Avail's Multichain Play:

Avail's integrations with Arbitrum, Optimism, Polygon, StarkWare, and zkSync represent major partnership wins, but the protocol's actual mainnet usage lags behind announcements.

The 4MB per block throughput (versus Celestia's current 8MB and Matcha's upcoming 128MB) creates a performance gap that limits Avail's competitiveness for high-volume rollups.

Avail's true differentiator is multichain flexibility. As blockchain infrastructure fragments across Ethereum L2s, alternative L1s, and application-specific chains, the need for a neutral data availability layer that doesn't favor one ecosystem grows. Avail positions itself as that neutral infrastructure, with partnerships spanning multiple settlement layers and execution environments.

The Economics of DA Layer Choice:

Choosing the wrong data availability layer can increase rollup costs by 55x according to industry analysis. This cost differential stems from three factors:

  1. Throughput limitations creating data fee spikes during demand peaks
  2. Storage requirements forcing rollups to maintain expensive archive infrastructure
  3. Switching costs making it expensive to migrate once integrated

For gaming-focused Layer 3 rollups generating massive state updates, the choice between Celestia's low-cost modular DA (especially post-Matcha) versus more expensive alternatives can mean the difference between sustainable economics and bleeding capital on data fees. This explains why Celestia is projected to dominate gaming L3 adoption in 2026.

The Path Forward: Implications for Rollup Economics and Blockchain Architecture

The data availability wars of 2026 represent more than infrastructure competition—they're reshaping fundamental assumptions about how blockchains scale and how rollup economics work.

Celestia's Matcha upgrade and Fibre Blockspace roadmap make it clear that data availability is no longer the bottleneck for blockchain scalability. With 128MB blocks in production and 1 Tb/s demonstrated in testing, the constraint shifts elsewhere—to execution layer optimization, state growth management, and cross-rollup interoperability. This is a profound shift. For years, the assumption was that data availability would limit how many rollups could scale simultaneously. Celestia is systematically invalidating that assumption.

The modular architecture philosophy is winning. Every major rollup framework now supports pluggable data availability layers rather than forcing dependence on Ethereum mainnet. This architectural choice validates the core insight behind Celestia's founding: that monolithic blockchains forcing every node to do everything create unnecessary trade-offs, while modular separation allows each layer to optimize independently.

Different DA layers are crystallizing around distinct use cases rather than competing head-to-head. Celestia serves rollups prioritizing cost efficiency, maximum decentralization, and proven production scale. EigenDA appeals to Ethereum-native projects willing to accept DAC trust assumptions for higher throughput. Avail targets multichain infrastructure needing neutral coordination across ecosystems. Rather than a single winner, the market is segmenting by architectural priorities.

Data availability costs are trending toward zero, which changes rollup business models. As Celestia's block sizes grow and competition intensifies, the marginal cost of posting data approaches negligible levels. This removes one of the largest variable costs in rollup operations, shifting economics toward fixed infrastructure costs (sequencers, provers, state storage) rather than per-transaction DA fees. Rollups can increasingly focus on execution innovation rather than worrying about data bottlenecks.

The next chapter of blockchain scaling isn't about whether rollups can access affordable data availability—Celestia's Matcha upgrade and Fibre roadmap make that inevitable. The question is what applications become possible when data is no longer the constraint. High-frequency trading venues running entirely on-chain. Massive multiplayer gaming worlds with persistent state. AI model coordination across decentralized compute networks. These applications were economically infeasible when data availability limited throughput and spiked costs unpredictably. Now the infrastructure exists to support them at scale.

For blockchain developers in 2026, the data availability layer choice has become as critical as choosing which L1 to build on was in 2020. Celestia's market position, production-proven scalability roadmap, and ecosystem integrations make it the safe default. EigenDA offers higher throughput for Ethereum-aligned projects accepting DAC trust models. Avail provides multichain flexibility for teams coordinating across ecosystems. All three have viable paths forward—but Celestia's 50% market share, Matcha upgrade, and Fibre vision position it to define what "data availability at scale" means for the next generation of blockchain infrastructure.

Ethereum Layer 2 Solutions in 2026: Arbitrum, Optimism, and zkSync Head-to-Head

· 13 min read
Dora Noda
Software Engineer

When Ethereum gas fees hit $50 during network congestion in 2024, the Layer 2 revolution wasn't just a nice-to-have—it became infrastructure-critical. Fast forward to February 2026, and the landscape has transformed dramatically. Three giants now dominate: Arbitrum with $16.63 billion in TVL, Optimism's Superchain ecosystem at $6 billion, and zkSync's zero-knowledge infrastructure powering institutional adoption from Deutsche Bank to tokenized securities. But which L2 solution actually wins for your use case?

The answer isn't straightforward. While transaction fees have plummeted to sub-penny levels across all three platforms, the architectural choices each team made are now crystallizing into distinct competitive advantages. Arbitrum's Stylus upgrade brings Rust and C++ to smart contracts. Optimism's OP Stack powers an interconnected web of L2s including Base and Worldcoin. zkSync Era deploys hyperchains with customizable privacy settings. The L2 wars aren't about who's fastest anymore—they're about who builds the most developer-friendly, interoperable, and future-proof infrastructure.

The TVL Leadership Race: Arbitrum's Commanding Position

Total value locked tells a story of user confidence and capital allocation. As of November 2025, Arbitrum One leads the entire Layer 2 ecosystem with approximately 44% of total L2 value locked—translating to $16.63 billion in bridged assets. Base Chain follows with 33% market share at $10 billion TVL, while OP Mainnet secures 6% with $6 billion TVL.

What's driving Arbitrum's dominance? The platform has become the de facto home for DeFi protocols and gaming applications, thanks to deep liquidity pools and a mature developer ecosystem. Projects launching on Arbitrum benefit from immediate access to billions in liquidity, making it the natural choice for complex financial applications requiring sophisticated capital efficiency.

zkSync's positioning is different but equally strategic. With $3.5 billion TVL distributed across zkSync Era, StarkNet, and Scroll, ZK-rollup solutions collectively represent about 10% of the L2 market. Despite lower absolute TVL compared to optimistic rollup competitors, zkSync is carving out dominance in high-value transactions, institutional use cases, and privacy-sensitive applications—exactly where zero-knowledge proofs provide irreplaceable advantages.

The TVL distribution reveals market segmentation rather than a winner-take-all dynamic. Arbitrum wins for established DeFi, Optimism's Superchain wins for ecosystem interoperability, and zkSync wins for institutional compliance and privacy requirements.

Technology Architectures: Optimistic vs. Zero-Knowledge Proofs

The fundamental technical split between these L2s shapes everything from transaction finality to gas costs. Arbitrum and Optimism both deploy optimistic rollups, which assume transactions are valid by default and only compute fraud proofs if someone challenges them during a roughly 7-day dispute period. zkSync Era uses ZK-rollups, which generate cryptographic proofs of transaction validity before submitting to Ethereum mainnet.

Arbitrum's implementation of optimistic rollups delivers 40–60 transactions per second with full EVM compatibility. The platform's February 2025 Stylus upgrade changed the game by introducing WebAssembly support alongside EVM execution. Smart contracts written in Rust, C, and C++ can now run on Arbitrum, compiled to WASM for significantly better performance than Solidity on computationally intensive operations. This makes Arbitrum particularly attractive for gaming engines, AI model inference, and cryptographic operations where every millisecond counts.

Optimism runs on similar optimistic rollup foundations but achieves higher throughput at approximately 130 TPS. The OP Stack—Optimism's modular blockchain framework—is fully open source and configurable layer by layer. This architectural choice enabled the Superchain vision: multiple L2 chains sharing bridging protocols, governance systems, and development tooling. Base, the Coinbase-backed L2 with massive retail onboarding potential, runs on OP Stack. So does Worldcoin's network. This shared infrastructure creates powerful network effects where liquidity pools across member chains and developers deploy once to serve multiple networks.

zkSync Era takes a radically different approach with ZK-rollups achieving 12–15 TPS while maintaining EVM compatibility through zkEVM implementation. The transaction throughput is lower, but the architecture enables features impossible with optimistic rollups: instant finality without 7-day withdrawal delays, native privacy through zero-knowledge proofs, and granular control over data availability modes (rollup, validium, or volition configurations).

zkSync's ZK Stack framework powers hyperchains—customizable L3 networks that can choose their own data availability, tokenomics, and sequencing configurations. Deutsche Bank's Project Dama 2, which involves 24 financial institutions testing blockchain for asset tokenization under Singapore's regulatory sandbox, specifically chose zkSync technology. When compliance, auditability, and privacy must coexist, zero-knowledge proofs aren't optional.

Transaction Costs: The Sub-Penny Era Arrives

If you remember paying $50 for a simple Ethereum swap during 2024 network congestion, the 2026 fee landscape feels like science fiction. Average Ethereum mainnet gas prices fell from 7.141 gwei in January 2025 to approximately 0.50 gwei in January 2026—a 93% decrease. Many Layer 1 transfers now cost between $0 and $0.33, with Layer 2 networks delivering fees below $0.01 per transaction.

The breakthrough came from Ethereum's Dencun upgrade in March 2024, which introduced "blobs"—dedicated data availability space for rollups. By separating rollup data from regular transaction calldata, Dencun reduced L2 data posting costs by 50–90% across all platforms. Then in January 2026, Ethereum developers increased blob capacity again, further increasing throughput for Layer 2 settlement batches.

Arbitrum and zkSync Era frequently offer transaction fees below $0.10, with many periods running under $0.03 depending on network load and batch efficiency. Optimism's Superchain benefits from shared blob space across member chains, letting Base and OP Mainnet coordinate data posting for maximum cost efficiency.

The real-world impact is massive. Layer 2 networks combined are now processing close to 2 million transactions per day, while Ethereum mainnet handles roughly half that amount. The economic viability of micro-transactions—NFT minting, social media interactions, gaming asset transfers—fundamentally changed when fees dropped below one cent. Applications that were economically impossible on Ethereum L1 are now thriving on L2s.

But there's a nuance: Layer 2 fees can occasionally spike above Ethereum mainnet during extreme L2-specific congestion events. When an L2 network processes an exceptionally high transaction volume, sequencer operations and proof generation can create temporary bottlenecks that push fees up. These events are rare but remind us that L2s aren't magic—they're sophisticated engineering solutions with their own resource constraints.

Developer Experience: Stylus, OP Stack, and ZK Stack

The developer experience determines which L2 wins the next generation of applications. Arbitrum's Stylus upgrade, shipped in 2024 and now production-ready, fundamentally expands what's possible with smart contracts. By supporting Rust, C, and C++ compiled to WebAssembly, Stylus lets developers bring decades of optimized libraries to blockchain. Cryptographic operations run orders of magnitude faster. Gaming engines can port physics calculations. AI inference becomes feasible on-chain.

The Stylus Sprint program received 147 high-quality submissions from developers building on this new paradigm, with 17 projects selected for their innovative approaches. These projects span developer tooling, privacy solutions, oracle implementations, and AI integration. Arbitrum Orbit—the framework for launching custom L3 chains on Arbitrum—now includes Stylus support by default, along with BoLD (Bounded Liquidity Delay) for improved security.

Optimism's developer advantage comes from ecosystem coordination. The OP Stack is modular, open source, and production-tested across multiple major L2s. When you build on OP Stack, you're not just deploying to Optimism—you're potentially reaching Base's Coinbase-powered user base, Worldcoin's global identity network, and future Superchain members. The interoperability layer launching in 2026 creates powerful network effects where multiple chains share liquidity and users benefit everyone in the ecosystem.

Market analysts from Messari project that successful Superchain integration could increase Optimism's total value locked by 40–60% during 2026, driven by cross-chain liquidity flows and unified developer tooling. The shared bridging protocol means users can move assets between Superchain members without the security risks of traditional bridges.

zkSync's ZK Stack provides granular control that institutional developers demand. Hyperchains can configure data availability as rollup (L1 data availability), validium (off-chain data with ZK proofs), or volition (users choose per-transaction). This flexibility matters for regulated entities that need compliance controls, enterprises requiring private transaction data, or consumer apps optimizing for the lowest possible costs.

The zkEVM implementation maintains EVM compatibility while enabling zero-knowledge features. Multiple zkEVM implementations are expected to reach full production maturity in 2026, narrowing the execution gap between zkEVMs and native EVM chains. Early zkSync Lite (Ethereum's first ZK-rollup) will shut down in 2026 as the protocol consolidates operations around zkSync Era and ZK Stack chains—a sign of strategic focus rather than retreat.

Ecosystem Maturity: DeFi, Gaming, and Institutional Adoption

Where each L2 shines depends on your sector. Arbitrum owns DeFi with the deepest liquidity for automated market makers, lending protocols, and derivatives platforms. GMX, Uniswap, Aave, and Curve all have major deployments on Arbitrum. The platform's high transaction throughput and Stylus performance optimizations make it ideal for complex financial operations requiring sophisticated state management and composability.

Arbitrum has also become a gaming hub. The combination of low fees, high throughput, and now Stylus-enabled performance for game logic makes it the natural choice for blockchain gaming. ApeChain—a dedicated Layer 3 blockchain built on Arbitrum Orbit for the ApeCoin ecosystem—demonstrates how gaming communities can launch custom chains while benefiting from Arbitrum's infrastructure and liquidity.

Optimism's Superchain strategy targets a different opportunity: becoming the infrastructure layer for consumer applications with massive user bases. Base's integration with Coinbase provides a compliance-first onboarding funnel that could make it the most widely used Layer 2 by 2026. When crypto apps need to serve millions of retail users with regulatory clarity, Base on OP Stack is increasingly the default choice.

The Superchain vision extends beyond Base. By creating a network of interoperable L2s sharing standards and governance, Optimism is building something closer to an operating system for blockchain applications than a single chain. Liquidity becomes pooled across member chains, market makers can deploy capital once and serve multiple networks, and traders tap into unified order books regardless of which chain they're on.

zkSync Era is winning institutional adoption specifically because of zero-knowledge technology. Project Dama 2 with Deutsche Bank and 24 financial institutions testing asset tokenization chose zkSync for good reason: regulatory compliance often requires transaction privacy, selective disclosure, and cryptographic auditability that only ZK-proofs can provide. When your transaction involves regulated securities, real estate tokens, or compliance-sensitive financial instruments, the ability to prove validity without revealing details isn't optional.

zkSync hyperchains enable institutional use cases to deploy private execution environments while maintaining settlement security on Ethereum. Over 100 transactions per second with sub-cent fees and customizable privacy settings make zkSync the clear choice for institutions that need blockchain efficiency without sacrificing compliance controls.

The 2026 Verdict: Which L2 Wins?

The answer depends entirely on what you're building. Arbitrum wins for established DeFi protocols, complex financial applications, and blockchain gaming that needs raw performance. With 44% L2 market share, $16.63 billion TVL, and Stylus enabling Rust/C++ smart contracts, Arbitrum has cemented its position as the DeFi and gaming home.

Optimism and its Superchain ecosystem win for consumer applications, interoperable L2 infrastructure, and projects that benefit from shared liquidity across chains. Base's Coinbase integration provides the strongest retail onboarding funnel in crypto, while OP Stack's modularity makes it the framework of choice for new L2 launches. The 40–60% TVL growth projected for 2026 reflects accelerating Superchain network effects.

zkSync Era wins for institutional adoption, privacy-sensitive applications, and use cases requiring cryptographic compliance features. Deutsche Bank's asset tokenization project, customizable hyperchains for enterprise deployments, and ZK-proof architecture that enables selective disclosure make zkSync the institutional-grade L2 infrastructure.

The Layer 2 landscape in 2026 isn't about one winner—it's about three distinct architectural paths serving different market segments. Developers are choosing their L2 based on liquidity needs, privacy requirements, interoperability strategy, and developer tooling preferences. All three platforms are processing millions of transactions daily with sub-penny fees. All three have vibrant ecosystems with billions in TVL.

What's clear is that Ethereum's L2-centric scaling roadmap is working. Combined L2 transaction volume now exceeds Ethereum mainnet. Fees have fallen 90–99% compared to 2024 congestion peaks. New use cases—from micro-transactions to institutional securities—are only possible because of L2 infrastructure.

The real competition isn't between Arbitrum, Optimism, and zkSync anymore. It's between the Ethereum L2 ecosystem as a whole and alternative L1 blockchains. When you can deploy on Arbitrum for DeFi, Base for consumer apps, and zkSync for institutional use cases—all while maintaining Ethereum's security guarantees and shared liquidity—the value proposition becomes overwhelming.

Sui Blockchain's Scalability Breakthrough: How Mysticeti V2 and Protocol Innovations Are Redefining Performance in 2026

· 11 min read
Dora Noda
Software Engineer

While most Layer 1 blockchains struggle to balance speed, security, and decentralization, Sui is quietly rewriting the rules. In January 2026, the network achieved what many thought impossible: 390-millisecond transaction finality with the capacity to process 297,000 transactions per second—all while cutting validator costs in half. This isn't incremental progress. It's a paradigm shift.

The Mysticeti V2 Revolution: Sub-Second Finality Meets Massive Throughput

At the heart of Sui's 2026 performance leap lies Mysticeti V2, a consensus protocol upgrade that fundamentally reimagines how blockchains process transactions. Unlike traditional consensus mechanisms that separate validation and execution into distinct phases, Mysticeti V2 integrates transaction validation directly into the consensus process.

The results speak for themselves. Asian nodes experienced 35% latency reductions, while European nodes saw 25% improvements. But the headline number—390 milliseconds to finality—tells only part of the story. This places Sui's performance on par with centralized payment systems like Visa, but with the decentralization and security guarantees of a public blockchain.

The architectural innovation centers on eliminating redundant computational steps. Previous consensus models required validators to verify transactions multiple times across different stages. Mysticeti V2's validation-integrated approach allows each transaction to be verified and finalized in a single streamlined process. The impact extends beyond raw speed. By reducing validator CPU requirements by 50%, the upgrade democratizes network participation. Validators can now focus computational resources on transaction execution rather than consensus overhead—a crucial development for maintaining decentralization as throughput scales.

Perhaps most impressively, Mysticeti V2 enables genuine transaction concurrency. Multiple operations can be processed and finalized simultaneously, a capability that proves particularly valuable for DeFi platforms, real-time gaming, and high-frequency trading applications. When a decentralized exchange on Sui processes thousands of swaps during market volatility, each transaction confirms in under half a second without network congestion.

Privacy Meets Performance: Protocol-Level Confidentiality

While competitors grapple with bolting privacy features onto existing architectures, Sui is embedding confidentiality at the protocol level. By 2026, Sui plans to introduce native private transactions that make transaction details visible only to senders and receivers—without requiring users to opt in or utilize separate privacy layers.

This matters because privacy has historically come at the cost of performance. Zero-knowledge rollups on Ethereum sacrifice throughput for confidentiality. Privacy-focused chains like Zcash struggle to match mainstream blockchain speeds. Sui's approach sidesteps this trade-off by integrating privacy into the base protocol alongside Mysticeti V2's performance optimizations.

The implementation leverages post-quantum cryptography through CRYSTALS-Dilithium and FALCON algorithms. This forward-thinking design addresses an often-overlooked threat: quantum computing's potential to break current encryption standards. While most blockchains treat quantum resistance as a distant concern, Sui is future-proofing privacy guarantees today.

For institutional users, protocol-level privacy removes a significant adoption barrier. Financial institutions can now process transactions on a public blockchain without exposing proprietary trading strategies or client information. Regulatory compliance becomes simpler when sensitive data remains confidential by default rather than through complex layered solutions.

The Walrus Advantage: Programmable Decentralized Storage

Data availability remains blockchain's unsolved problem. Ethereum's rollups rely on off-chain data storage. Filecoin and Arweave offer decentralized storage but lack deep blockchain integration. Sui's Walrus protocol, which reached full decentralization in March 2025, bridges this gap by making storage programmable through native Sui objects.

Here's how it transforms the landscape: when an application publishes a data blob to Walrus, it becomes represented by a Sui object with on-chain metadata. Move smart contracts can then control, route, and pay for storage programmatically. This isn't just convenient—it enables entirely new application architectures.

Consider a decentralized social network storing user content. Traditional blockchain approaches force developers to choose between expensive on-chain storage and trust-dependent off-chain solutions. Walrus allows the application to store gigabytes of media on-chain affordably while maintaining full programmability. Smart contracts can automatically archive old content, manage access permissions, or even monetize storage through tokenized incentives.

The underlying technology—erasure coding—makes this economically viable. Walrus encodes data blobs into smaller "slivers" distributed across storage nodes. Even if two-thirds of slivers disappear, the original data can be reconstructed from the remaining fragments. This redundancy ensures availability without the cost multiplier of traditional replication.

For AI applications, Walrus unlocks previously impractical use cases. Training datasets spanning hundreds of gigabytes can be stored on-chain with verifiable provenance. Smart contracts can automatically compensate data providers when AI models access their datasets. The entire machine learning pipeline—from data storage to model inference to compensation—can execute on-chain without performance bottlenecks.

DeFi Ecosystem Maturation: From $400M to $1.2B in Stablecoins

Numbers tell Sui's DeFi story more eloquently than adjectives. In January 2025, stablecoin volume on Sui totaled $400 million. By May 2025, that figure had tripled to nearly $1.2 billion. Monthly stablecoin transfer volume exceeded $70 billion, with cumulative DEX volume surpassing $110 billion.

The ecosystem's flagship protocols reflect this explosive growth. Suilend, Sui's leading lending platform, holds $745 million in total value locked with 11% monthly growth. Navi Protocol manages $723 million, growing 14% monthly. But the standout performer is Momentum, which achieved a staggering 249% growth spike to reach $551 million in TVL.

This isn't speculative capital chasing yields. The growth reflects genuine DeFi utility enabled by Sui's technical advantages. When transaction finality drops to 390 milliseconds, arbitrage bots can exploit price differences across exchanges with unprecedented efficiency. When gas fees remain predictable and low, yield farming strategies that were marginally profitable on Ethereum become economically viable.

The programmable transaction block (PTB) architecture deserves special attention. A single PTB can batch up to 1,024 sequential Move function calls into one transaction. For complex DeFi strategies—such as flash loans combined with multi-hop swaps and collateral management—this dramatically reduces gas costs and execution risk compared to chains requiring multiple separate transactions.

Institutional adoption signals validate the ecosystem's maturity. At Consensus Hong Kong 2026, Sui executives reported that institutional demand for crypto infrastructure had "never been higher." The convergence of spot Bitcoin ETF success, regulatory clarity, and digital asset treasury adoption created ideal conditions for enterprise blockchain deployment.

Scaling the "Sui Stack": From Infrastructure to Applications

The infrastructure is ready. Now comes the hard part: building applications that mainstream users actually want.

Sui's 2026 strategic focus pivots from protocol development to ecosystem enablement. The "Sui Stack"—consisting of Mysticeti V2 for consensus, Walrus for storage, and native privacy for confidentiality—provides developers with tools rivaling centralized platforms while maintaining decentralization guarantees.

Consider the gaming vertical. Real-time multiplayer games demand sub-second state updates, affordable microtransactions, and massive throughput during peak activity. Sui's technical stack delivers on all three requirements. A blockchain-based battle royale game can process thousands of concurrent player actions, update game state every 390 milliseconds, and charge fractions of a cent per transaction.

The Bitcoin finance (BTCFi) expansion represents another strategic priority. By bridging Bitcoin liquidity to Sui's high-performance environment, developers can build DeFi applications unavailable on Bitcoin's native Layer 1. Wrapped Bitcoin on Sui benefits from instant finality, programmable smart contracts, and seamless integration with the broader DeFi ecosystem.

Social applications finally become viable when storage is affordable and transactions confirm instantly. A decentralized Twitter alternative can store multimedia posts on Walrus, process millions of likes and shares through PTBs, and maintain user privacy through protocol-level confidentiality—all while delivering UX comparable to Web2 platforms.

The Move Language Advantage: Security Meets Expressiveness

While much attention focuses on consensus and storage innovations, Sui's choice of the Move programming language provides often-underestimated advantages. Developed originally by Meta for the Diem project, Move introduces resource-oriented programming that treats digital assets as first-class language primitives.

Traditional smart contract languages like Solidity represent tokens as balance mappings in contract storage. This abstraction creates security vulnerabilities—reentrancy attacks, for instance, exploit the gap between updating balances and transferring value. Move's resource model makes such attacks impossible by design. Assets are actual objects that can only exist in one location at a time, enforced at the compiler level.

For developers, this means spending less time defending against attack vectors and more time building features. The compiler catches entire categories of bugs that plague other ecosystems. When combined with Sui's object model—where each asset is a unique object with its own storage rather than an entry in a global mapping—parallelization becomes trivial. Transactions operating on different objects can execute concurrently without risk of conflicts.

The security benefits compound over time. As Sui's DeFi ecosystem manages billions in total value locked, the absence of major exploits attributable to Move language vulnerabilities builds institutional confidence. Auditing Move smart contracts requires fewer security specialists to review fewer potential attack surfaces compared to equivalent Solidity contracts.

Network Effects and Competitive Positioning

Sui doesn't exist in isolation. Solana offers high throughput, Ethereum provides unmatched liquidity and developer mindshare, and newer Layer 1s compete on various performance metrics. What distinguishes Sui in this crowded landscape?

The answer lies in architectural coherence rather than any single feature. Mysticeti V2's consensus, Walrus storage, Move language security, and protocol-level privacy weren't bolted together—they were designed as integrated components of a unified system. This coherence enables capabilities impossible on platforms built through accumulated technical debt.

Consider cross-chain interoperability. Sui's object model and Move language make atomic cross-chain transactions simpler to implement securely. When bridging assets from Ethereum, wrapped tokens become native Sui objects with full language-level security guarantees. The programmable storage layer allows decentralized bridges to maintain proof data on-chain affordably, reducing reliance on trusted validators.

The regulatory landscape increasingly favors platforms offering native privacy and compliance features. While existing chains scramble to retrofit these capabilities, Sui's protocol-level implementation positions it favorably for institutional adoption. Financial institutions exploring blockchain settlement prefer systems where confidentiality doesn't depend on optional user behavior or separate privacy layers.

Developer experience matters more than raw performance metrics for long-term success. Sui's tooling—from the Move compiler's helpful error messages to the extensive simulation capabilities for testing complex transactions—lowers the barrier for building sophisticated applications. When combined with comprehensive documentation and growing educational resources, the ecosystem becomes increasingly accessible to developers outside the crypto-native community.

The Road Ahead: Challenges and Opportunities

Despite impressive technical achievements, significant challenges remain. Network decentralization requires continuous attention as validator requirements scale with throughput. While Mysticeti V2 reduced computational costs, processing 297,000 TPS still demands substantial hardware. Balancing performance with accessibility for validators will define Sui's long-term decentralization trajectory.

Ecosystem liquidity, while growing rapidly, lags behind established chains. Total value locked of $1.04 billion in early 2026 represents impressive growth but pales next to Ethereum's DeFi ecosystem. Attracting major protocols and liquidity providers remains essential for establishing Sui as a primary DeFi venue rather than a secondary option.

User adoption hinges on application quality more than infrastructure capabilities. The blockchain trilemma may be solved, but the "why should users care" question persists. Successful mainstream adoption requires applications that are genuinely superior to Web2 alternatives, not merely blockchain-enabled versions of existing services.

Regulatory uncertainty affects all blockchain platforms, but Sui's emphasis on privacy features could invite additional scrutiny. While protocol-level confidentiality serves legitimate institutional use cases, regulators may demand access mechanisms or compliance frameworks. Navigating these requirements without compromising core privacy guarantees will test the ecosystem's adaptability.

Building on Solid Foundations

Sui's 2026 innovations demonstrate that blockchain scalability isn't a zero-sum trade-off between speed, security, and decentralization. Mysticeti V2 proves consensus protocols can achieve sub-second finality without sacrificing validator participation. Walrus shows storage can be both decentralized and programmable. Protocol-level privacy removes the false choice between confidentiality and performance.

The infrastructure is ready. The question now is whether the ecosystem can deliver applications that justify the technical sophistication. Gaming, DeFi, social platforms, and enterprise solutions all show promise, but promise must translate into adoption.

For developers seeking a high-performance blockchain that doesn't compromise on security or decentralization, Sui offers a compelling platform. For institutions requiring privacy and compliance features, the protocol-level implementation provides advantages competitors struggle to match. For users, the benefits remain latent—dependent on applications yet to be built.

The scalability problem is solved. Now comes the harder challenge: proving it matters.

Ethereum's 2026 Biannual Upgrade Roadmap: From Mega-Upgrades to Strategic Incrementalism

· 16 min read
Dora Noda
Software Engineer

When Ethereum's core developers announced Fusaka and Glamsterdam—two major network upgrades slated for 2026—they weren't just unveiling a technical roadmap. They were signaling a fundamental shift in how the world's largest smart contract platform evolves: from monolithic "big bang" releases to predictable, biannual incremental improvements. This strategic pivot could be the difference between Ethereum maintaining its dominance and losing ground to faster-moving competitors.

The stakes have never been higher. With Layer 2 solutions processing billions in daily volume, institutional adoption accelerating, and competitors like Solana claiming "100,000 TPS" headlines, Ethereum faces a credibility test: can it scale without compromising decentralization or security? The 2026 roadmap answers with a resounding yes—but the path isn't what most expected.

The New Ethereum: Incremental Revolution Over Monolithic Disruption

Ethereum's historical approach to upgrades has been characterized by years-long development cycles culminating in transformative releases. The Merge in 2022 took nearly six years from conception to execution, transitioning the network from Proof-of-Work to Proof-of-Stake in one fell swoop. While successful, this model carries inherent risks: extended development timelines, coordination complexity across thousands of nodes, and the potential for catastrophic failures that could freeze billions in assets.

The 2026 strategy represents a departure from this model. Ethereum developers now plan two major network upgrades annually, prioritizing smaller, iterative updates that reduce the risk of large-scale disruptions while ensuring continuous optimization. This biannual cadence prioritizes predictability and safety, a stark contrast to the "big bang" overhauls of the past.

Why the shift? The answer lies in Ethereum's maturation as critical financial infrastructure. With over $68 billion in DeFi total value locked and institutional players like BlackRock tokenizing assets on-chain, the network can no longer afford multi-year gaps between improvements. The biannual model borrows from software development best practices: ship early, ship often, and iterate based on real-world performance.

Fusaka: The Scalability Foundation That Just Went Live

Fusaka activated on Ethereum mainnet on December 3, 2025, marking the first implementation of this new upgrade philosophy. Far from a mere incremental patch, Fusaka bundles 13 EIPs organized around three core objectives: scaling Layer 2s, improving Layer 1 execution efficiency, and enhancing developer and user experience.

PeerDAS: The Headline Innovation

The crown jewel of Fusaka is PeerDAS (Peer Data Availability Sampling), defined in EIP-7594. PeerDAS introduces a new networking protocol that allows nodes to verify blob data availability through sampling rather than downloading entire blobs. This fundamentally changes Ethereum's data availability model.

Previously, every full node needed to store every blob—the data packets used by Layer 2 rollups to post transaction data to Ethereum. This created a bottleneck: as blob usage increased, node hardware requirements ballooned, threatening decentralization. PeerDAS solves this by splitting blob data across many nodes and collectively verifying its availability through cryptographic sampling.

The impact is dramatic. Following Fusaka's activation, Ethereum implemented Blob Parameter Only (BPO) forks to gradually increase blob capacity:

  • BPO 1 (December 17, 2025): Target 10 blobs per block, maximum 15
  • BPO 2 (January 7, 2026): Target 14 blobs per block, maximum 21

Early data shows 40–60% Layer 2 fee reductions within the first month as PeerDAS activated and blob throughput scaled, with projections of 90%+ reductions as the network ramps to higher blob counts throughout 2026. For context, Optimism and Arbitrum—two of the largest Ethereum L2s—saw transaction fees drop from cents to fractions of cents, making DeFi and NFT transactions economically viable at scale.

Gas Limit Increases and Execution Efficiency

Beyond data availability, Fusaka also targets Layer 1 execution capacity. Ethereum's available block gas limit will rise from 45 million to 60 million, expanding computation and transactions per block. This increase, combined with EIP-7825's transaction gas limit cap, improves block composability and guarantees more transactions per block.

These changes aren't just about raw throughput. They're about eliminating execution and block propagation bottlenecks that currently force transactions through a mostly linear pipeline. Fusaka increases both the raw throughput and the effective throughput, ensuring that Ethereum can handle peak demand without network congestion.

Additional optimizations include:

  • ModExp Precompile Improvements (EIP-7883 and EIP-7823): These EIPs optimize cryptographic operations by increasing gas costs to accurately reflect computational complexity and setting upper bounds for ModExp operations, ensuring resource-intensive tasks are properly priced.
  • Enhanced Block Propagation: Improvements that reduce latency between block production and network-wide validation, critical for maintaining security as block sizes increase.

Glamsterdam: The Parallel Execution Breakthrough

If Fusaka lays the foundation for scalability, Glamsterdam—scheduled for the first half of 2026—delivers the architectural breakthrough that could push Ethereum toward 100,000+ TPS. The upgrade introduces Block Access Lists and enshrined Proposer-Builder Separation (ePBS), two innovations that fundamentally transform how Ethereum processes transactions.

Block Access Lists: Unlocking Parallel Execution

Ethereum's current execution model is largely sequential: transactions are processed one after another in the order they appear in a block. This works for a single-threaded system but wastes the potential of modern multi-core processors. Block Access Lists enable a transition toward a multi-core processing model where independent transactions can be executed simultaneously.

The mechanism is elegant: transactions declare upfront which parts of Ethereum's state they will read or modify (the "access list"). Validators can then identify transactions that don't conflict and execute them in parallel across multiple CPU cores. For example, a swap on Uniswap and a transfer on a completely different token contract can run concurrently, doubling effective throughput without changing hardware requirements.

Parallel execution pushes Ethereum's mainnet toward near-parallel transaction processing, with nodes handling multiple independent chunks of state simultaneously, cutting bottlenecks that currently force transactions through a mostly linear pipeline. Once the new execution model proves stable, core teams plan to ratchet the gas limit from around 60 million to roughly 200 million, a 3.3x increase that would bring Ethereum's Layer 1 capacity into territory previously reserved for "high-performance" chains.

Enshrined Proposer-Builder Separation (ePBS): Democratizing MEV

Maximum Extractable Value (MEV)—the profit validators can extract by reordering, inserting, or censoring transactions—has become a controversial topic in Ethereum. Specialized block builders currently capture billions annually by optimizing transaction ordering for profit, creating centralization pressures and raising censorship concerns.

ePBS is a protocol-level change designed to mitigate risks by moving block-building logic directly into the core code. Instead of validators outsourcing block construction to third-party builders, the protocol itself handles the separation between block proposers (who validate) and block builders (who optimize ordering).

This democratizes the rewards of block production by ensuring that MEV is distributed more fairly across all validators, not just those with access to sophisticated builder infrastructure. It also lays groundwork for parallel transaction processing by standardizing how transactions are batched and ordered, enabling future optimizations that would be impossible with today's ad-hoc builder ecosystem.

Hegota: The Stateless Node Endgame

Scheduled for the second half of 2026, Hegota represents the culmination of Ethereum's 2026 roadmap: the transition to stateless nodes. Hegota introduces Verkle Trees, a data structure replacing Merkle Patricia Trees. This transition enables the creation of significantly smaller cryptographic proofs, allowing for the launch of "stateless clients," which can verify the entire blockchain without requiring participants to store hundreds of gigabytes of historical data.

Today, running an Ethereum full node requires 1TB+ of storage and substantial bandwidth. This creates a barrier to entry for individuals and small operators, pushing them toward centralized infrastructure providers. Stateless nodes change the equation: by using Verkle proofs, a node can validate the current state of the network with just a few megabytes of data, dramatically lowering hardware requirements.

The implications for decentralization are profound. If anyone can run a full node on a laptop or even a smartphone, Ethereum's validator set could expand from tens of thousands to hundreds of thousands or even millions. This hardening of the network against centralization pressures is perhaps the most strategic element of the 2026 roadmap—scalability without sacrificing decentralization, the blockchain trilemma's holy grail.

Why Biannual Upgrades Matter: Strategic vs. Tactical Scaling

The shift to biannual upgrades isn't just about faster iteration—it's about strategic positioning in a competitive landscape. Ethereum's competitors haven't been idle. Solana claims 65,000 TPS with sub-second finality. Sui and Aptos leverage parallel execution from day one. Even Bitcoin is exploring Layer 2 programmability through projects like Stacks and Citrea.

Ethereum's traditional upgrade cycle—multi-year gaps between major releases—created windows of opportunity for competitors to capture market share. Developers frustrated with high gas fees migrated to alternative chains. DeFi protocols forked to faster networks. The 2026 roadmap closes this window by ensuring continuous improvement: every six months, Ethereum delivers meaningful enhancements that keep it at the technological frontier.

But there's a deeper strategic logic at play. The biannual cadence prioritizes smaller, more frequent upgrades over monolithic releases, ensuring continuous improvement without destabilizing the ecosystem. This matters for institutional adoption: banks and asset managers need predictability. A network that ships regular, tested improvements is far more attractive than one that undergoes radical transformations every few years.

Consider the contrast with the Merge. While successful, it represented an existential risk: if consensus had failed, the entire network could have halted. The 2026 upgrades, by comparison, are additive. PeerDAS doesn't replace the existing data availability system—it extends it. Block Access Lists don't break existing transaction processing—they enable an additional parallel execution layer. This incremental approach de-risks each upgrade while maintaining momentum.

The Technical Trilemma: Can Ethereum Have It All?

The blockchain trilemma—the notion that blockchains can only achieve two of three properties: decentralization, security, and scalability—has haunted Ethereum since its inception. The 2026 roadmap represents Ethereum's most ambitious attempt to prove the trilemma wrong.

Scalability: Fusaka's PeerDAS and Glamsterdam's parallel execution deliver 10x–100x throughput improvements. The target of 100,000+ TPS puts Ethereum in the same league as Visa's peak capacity.

Decentralization: Hegota's stateless nodes lower hardware requirements, expanding the validator set. PeerDAS's sampling mechanism distributes data storage across thousands of nodes, preventing centralization around a few high-capacity operators.

Security: ePBS reduces MEV-related censorship risks. The incremental upgrade model minimizes the attack surface of each change. And Ethereum's $68B+ in staked ETH provides economic security unmatched by any other blockchain.

But the real test isn't technical—it's adoption. Will Layer 2s migrate to take advantage of cheaper blob fees? Will developers build applications that leverage parallel execution? Will institutions trust a network undergoing biannual upgrades?

What This Means for Developers and Users

For developers building on Ethereum, the 2026 roadmap offers concrete benefits:

  1. Lower Layer 2 Costs: With blob fees potentially dropping 90%, deploying rollup-based applications becomes economically viable for use cases previously relegated to centralized databases—think micro-transactions, gaming, and social media.

  2. Higher Layer 1 Throughput: The gas limit increase to 200 million means complex smart contracts that previously couldn't fit in a single block become feasible. DeFi protocols can offer more sophisticated financial instruments. NFT marketplaces can handle batch mints at scale.

  3. Improved User Experience: Account abstraction via EIP-7702 (introduced in the earlier Pectra upgrade) combined with Glamsterdam's execution efficiency means users can interact with dApps without worrying about gas fees, transaction batching, or wallet seed phrases. This UX leap could finally bring blockchain to mainstream adoption.

For users, the changes are equally significant:

  • Cheaper Transactions: Whether trading on Uniswap, minting NFTs, or transferring tokens, transaction costs on Layer 2s will drop to fractions of a cent.
  • Faster Confirmations: Parallel execution means transactions settle faster, reducing the "pending" state that frustrates users.
  • Enhanced Security: ePBS and stateless nodes make Ethereum more resilient to censorship and centralization, protecting user sovereignty.

Risks and Trade-offs: What Could Go Wrong?

No upgrade roadmap is without risks. The 2026 plan introduces several potential failure modes:

Coordination Complexity: Biannual upgrades require tight coordination across client teams, infrastructure providers, and the broader ecosystem. A bug in any of the 13+ EIPs could delay or derail the entire release.

Validator Centralization: While stateless nodes lower barriers to entry, the reality is that most validators run on cloud infrastructure (AWS, Azure, Google Cloud). If the gas limit increases to 200 million, only high-performance servers may be able to keep up, potentially centralizing validation despite stateless client availability.

MEV Evolution: ePBS aims to democratize MEV, but sophisticated actors may find new ways to extract value, creating an arms race between protocol designers and profit-seeking builders.

Layer 2 Fragmentation: As blob fees drop, the number of Layer 2s could explode, fragmenting liquidity and user experience across dozens of incompatible chains. Cross-chain interoperability remains an unsolved challenge.

The Ethereum roadmap includes a validator risk that's bigger than many think: to deliver the massive throughput gains, the network must balance increased computational demands with the need to maintain a diverse, decentralized validator set.

Looking Ahead: The Post-2026 Roadmap

The 2026 upgrades aren't endpoints—they're waypoints on Ethereum's multi-year scaling journey. Vitalik Buterin's roadmap envisions further improvements beyond Glamsterdam and Hegota:

  • The Surge: Continued scaling work to reach 100,000+ TPS through Layer 2 optimizations and data availability improvements.
  • The Scourge: Further MEV mitigation and censorship resistance beyond ePBS.
  • The Verge: Full stateless client implementation with Verkle Trees and eventually, quantum-resistant cryptography.
  • The Purge: Reducing historical data storage requirements, making the network even more lightweight.
  • The Splurge: All the other improvements that don't fit neatly into categories—account abstraction enhancements, cryptographic upgrades, and developer tooling.

The biannual upgrade model makes this long-term roadmap executable. Instead of waiting years for "The Surge" to complete, Ethereum can ship components incrementally, validating each step before moving forward. This adaptive approach ensures the network evolves in response to real-world usage patterns rather than theoretical projections.

Institutional Implications: Why Wall Street Cares About Upgrades

Ethereum's 2026 roadmap matters far beyond the crypto community. BlackRock's BUIDL tokenized money market fund holds over $1.8 billion in on-chain assets. Fidelity, JPMorgan, and Goldman Sachs are experimenting with blockchain-based settlement. The European Central Bank is testing digital euro prototypes on Ethereum.

For these institutions, predictability is paramount. The biannual upgrade cadence provides a transparent, scheduled roadmap that allows enterprises to plan infrastructure investments with confidence. They know that in H1 2026, Glamsterdam will deliver parallel execution. They know that in H2 2026, Hegota will enable stateless nodes. This visibility de-risks blockchain adoption for risk-averse institutions.

Moreover, the technical improvements directly address institutional pain points:

  • Lower Costs: Reduced blob fees make tokenized asset transfers economically competitive with traditional settlement rails.
  • Higher Throughput: The 200 million gas limit target ensures Ethereum can handle institutional-scale transaction volumes—think thousands of tokenized stock trades per second.
  • Regulatory Compliance: ePBS's MEV mitigation reduces the risk of front-running and market manipulation, addressing SEC concerns about fair markets.

BlockEden.xyz provides enterprise-grade Ethereum infrastructure designed to scale with the network's 2026 upgrades—PeerDAS-optimized data availability, parallel execution-ready RPC endpoints, and seamless support across Ethereum mainnet and all major Layer 2s. Explore our Ethereum API services to build on infrastructure that evolves with the protocol.

The Bottom Line: Ethereum's Defining Year

2026 could be the year Ethereum definitively answers its critics. The complaints are familiar: "too slow," "too expensive," "can't scale." The biannual upgrade roadmap addresses each one head-on. Fusaka delivered the data availability scaling Layer 2s desperately needed. Glamsterdam will unlock parallel execution, bringing Ethereum's Layer 1 throughput into direct competition with high-performance chains. Hegota will democratize validation through stateless nodes, hardening decentralization.

But the real innovation isn't any single technical feature—it's the meta-strategy of incremental, predictable improvements. By shifting from mega-upgrades to biannual releases, Ethereum has adopted the development cadence of successful software platforms: iterate quickly, learn from production usage, and ship continuously.

The question isn't whether Ethereum can reach 100,000 TPS. The technology is proven. The question is whether the ecosystem—developers, users, institutions—will adapt quickly enough to leverage these improvements. If they do, Ethereum's 2026 roadmap could cement its position as the settlement layer for the internet of value. If they don't, competitors will continue to nibble at the edges, offering specialized solutions for gaming, DeFi, or payments.

One thing is certain: the days of waiting years between Ethereum upgrades are over. The 2026 roadmap isn't just a technical plan—it's a declaration that Ethereum is no longer a research project. It's critical infrastructure, and it's evolving at the speed of the internet itself.

LayerZero's Zero Network: Wall Street Bets Big on 2M TPS Blockchain

· 12 min read
Dora Noda
Software Engineer

When Citadel Securities, the trading giant that handles 47% of all U.S. retail equities volume, announces a blockchain partnership, the market pays attention. When it's joined by the New York Stock Exchange's parent company, the world's largest securities depository, Google Cloud, and Cathie Wood's ARK Invest—all backing a single blockchain—it signals something unprecedented.

LayerZero Labs' February 10, 2026 unveiling of Zero, a Layer-1 blockchain targeting 2 million transactions per second, represents more than another scalability play. It's Wall Street's most explicit bet yet that the future of global finance runs on permissionless rails.

From Cross-Chain Messaging to Institutional Infrastructure

LayerZero built its reputation solving blockchain's "walled garden" problem. Since its inception, the protocol has connected 165+ blockchains through its omnichain messaging infrastructure, enabling seamless asset and data transfer across previously incompatible networks. Developers building cross-chain applications have relied on LayerZero's Ultra Light Nodes (ULNs)—smart contracts that validate messages using block headers and transaction proofs—to bridge siloed ecosystems.

But cross-chain messaging, while foundational, wasn't designed for the demands of institutional trading infrastructure. When Citadel Securities processes over 1.7 billion shares daily, or when DTCC settles $2.5 quadrillion in securities annually, milliseconds matter. Traditional blockchain architectures, even high-performance ones, couldn't deliver the throughput, finality, or reliability Wall Street requires.

Zero represents LayerZero's evolution from connectivity layer to settlement infrastructure. The announcement positions it squarely in the race to become the blockchain backbone for tokenized securities, 24/7 trading, and real-time settlement—a market estimated to exceed $30 trillion by 2030.

The Heterogeneous Architecture Breakthrough

Zero's core innovation lies in what LayerZero calls its "heterogeneous architecture"—a fundamental rethinking of how blockchains divide labor. Traditional blockchains force every validator to replicate identical work: download blocks, execute transactions, verify state transitions. This redundancy prioritizes security but creates throughput bottlenecks.

Zero decouples execution from verification. Block Producers execute transactions, assemble blocks, and generate zero-knowledge proofs. Block Validators simply verify these proofs—a computationally lighter task that can run on consumer-grade hardware. By leveraging Jolt, LayerZero's proprietary ZK proving technology, validators confirm transaction validity in seconds without downloading full blocks.

This separation unlocks three compounding advantages:

Massive parallelization: Different zones can execute different transaction types simultaneously—EVM smart contracts, privacy-focused payments, high-frequency trading—all settling on the same network.

Hardware accessibility: When validators need only verify proofs rather than execute transactions, network participation doesn't require enterprise-grade infrastructure. This lowers centralization risk while maintaining security.

Real-time finality: Traditional ZK systems batch transactions to amortize proving costs. Jolt's efficiency enables real-time proof generation, finalizing transactions in seconds rather than minutes.

The result: a claimed 2 million TPS capacity across unlimited zones. If accurate, Zero would process transactions 100,000 times faster than Ethereum and significantly outpace even high-performance chains like Solana.

Three Zones, Three Use Cases

Zero launches in fall 2026 with three initial permissionless zones, each optimized for distinct institutional needs:

1. General Purpose EVM Zone

Fully compatible with Solidity smart contracts, this zone enables developers to deploy existing Ethereum applications without modification. For institutions experimenting with DeFi protocols or tokenized asset management, EVM compatibility lowers migration barriers while offering order-of-magnitude performance improvements.

2. Privacy-Focused Payments Infrastructure

Financial institutions moving trillions on-chain need confidentiality guarantees. This zone embeds privacy-preserving technology—likely leveraging zero-knowledge proofs or confidential computing—to enable compliant private transactions. DTCC's interest in "enhancing the scalability of its tokenization and collateral initiatives" suggests use cases in institutional settlement where transaction details must remain confidential.

3. Canonical Trading Environment

Designed explicitly for "trading across all markets and asset classes," this zone targets Citadel Securities' and ICE's core businesses. ICE has explicitly stated it's "examining applications tied to 24/7 trading and tokenized collateral"—a direct challenge to the traditional market structure that closes at 4 PM ET and settles on T+2 timelines.

This heterogeneous approach reflects a pragmatic recognition: there is no one-size-fits-all blockchain. Rather than forcing all use cases through a single virtual machine, Zero creates specialized execution environments optimized for specific workloads, unified by shared security and interoperability.

The Institutional Alignment

Zero's partner roster reads like a financial infrastructure who's who, and their involvement isn't passive:

Citadel Securities made a strategic investment in ZRO, LayerZero's native token, and is "providing market structure expertise to evaluate how its technology could apply to trading, clearing and settlement workflows." This isn't a proof-of-concept pilot—it's active collaboration on production infrastructure.

DTCC, which processes virtually all U.S. equities and fixed income settlements, sees Zero as a scalability unlock for its DTC Tokenization Service and Collateral App Chain. When the organization settling $2.5 quadrillion annually investigates blockchain rails, it signals institutional settlement moving on-chain at scale.

Intercontinental Exchange (ICE), owner of the NYSE, is preparing "trading and clearing infrastructure to support 24/7 markets and the potential integration of tokenized collateral." Traditional exchanges close daily; blockchains don't. ICE's participation suggests the boundary between TradFi and DeFi infrastructure is dissolving.

Google Cloud is exploring "blockchain-based micropayments and resource trading for AI agents"—a glimpse at how Zero's high throughput could enable machine-to-machine economies where AI agents autonomously transact for compute, data, and services.

ARK Invest didn't just invest in ZRO tokens; it took an equity stake in LayerZero Labs. Cathie Wood joined the company's advisory board—her first such role in years—and publicly stated, "Finance is moving on-chain, and LayerZero is a core innovation platform for this multi-decade shift."

This isn't crypto-native VCs betting on retail adoption. It's Wall Street's core infrastructure providers committing capital and expertise to blockchain settlement.

Interoperability at Launch: 165 Blockchains Connected

Zero doesn't launch in isolation. By leveraging LayerZero's existing omnichain messaging protocol, Zero connects to 165 blockchains from day one. This means liquidity, assets, and data from Ethereum, Solana, Avalanche, Polygon, Arbitrum, and 160+ other networks can seamlessly interact with Zero's high-throughput zones.

For institutional use cases, this interoperability is critical. A tokenized Treasury bond issued on Ethereum can serve as collateral for a derivative traded on Zero. A stablecoin minted on Solana can settle payments in Zero's privacy zone. Real-world assets tokenized across fragmented ecosystems can finally compose in a unified, high-performance environment.

LayerZero's cross-chain infrastructure uses Decentralized Verifier Networks (DVNs)—independent entities that validate messages between chains. Applications can define their own security thresholds, selecting specific DVNs and setting verification requirements. This modular security model lets risk-averse institutions customize trust assumptions rather than accepting protocol defaults.

The Timing: Why Now?

Zero's announcement arrives at a pivotal moment in crypto's institutional adoption curve:

Regulatory clarity is emerging. The U.S. GENIUS Act establishes stablecoin frameworks. MiCA brings comprehensive crypto regulation to the EU. Jurisdictions from Singapore to Switzerland have clear custody and tokenization rules. Institutions no longer face existential regulatory uncertainty.

Tokenized asset experiments are maturing. BlackRock's BUIDL fund, Franklin Templeton's OnChain U.S. Government Money Fund, and JP Morgan's Onyx have proven that institutions will move billions on-chain—if the infrastructure meets their standards.

24/7 markets are inevitable. When stablecoins enable instant settlement and tokenized securities trade around the clock, traditional market hours become artificial constraints. Exchanges like ICE must either embrace continuous trading or cede ground to crypto-native competitors.

AI agents need payment rails. Google's interest in micropayments for AI compute isn't speculative. As large language models and autonomous agents proliferate, they need programmable money to pay for APIs, datasets, and cloud resources without human intervention.

Zero positions itself at the intersection of these trends: the infrastructure layer enabling Wall Street's blockchain migration.

The Competitive Landscape

Zero enters a crowded field. Ethereum's rollup-centric roadmap, Solana's high-throughput architecture, Avalanche's subnet model, Cosmos' application-specific chains—all target institutional use cases with varying degrees of success.

What differentiates Zero is institutional commitment depth. When DTCC and Citadel actively collaborate on design—not just run pilots—it signals conviction that this infrastructure will handle production workflows. When ICE prepares to integrate tokenized collateral, it's architecting for real capital flows, not proof-of-concept demos.

The heterogeneous architecture also matters. Ethereum forces institutions to choose between mainnet security or L2 scalability. Solana prioritizes speed but lacks specialized execution environments. Zero's zone model promises customization without fragmentation—privacy payments, EVM contracts, and trading infrastructure sharing security and liquidity.

Whether Zero delivers on these promises remains to be seen. 2 million TPS is an ambitious target. Real-time ZK proving at scale is unproven. And institutional adoption, even with heavyweight backing, faces regulatory, operational, and cultural barriers.

What This Means for Developers

For blockchain developers, Zero presents intriguing opportunities:

EVM compatibility means existing Solidity contracts can deploy to Zero with minimal modifications, tapping into order-of-magnitude higher throughput without rewriting application logic.

Omnichain interoperability enables developers to build applications that compose liquidity and data across 165+ chains. A DeFi protocol could aggregate liquidity from Ethereum, settle trades on Zero, and distribute yields to users on Solana—all in a single transaction flow.

Institutional partnerships create distribution channels. Applications built on Zero gain access to DTCC's settlement networks, ICE's trading infrastructure, and Google Cloud's developer ecosystem. For teams targeting enterprise adoption, these integrations could accelerate go-to-market timelines.

Specialized zones allow applications to optimize for specific use cases. A privacy-preserving payment app doesn't need to compete for block space with high-frequency trading; each operates in its specialized environment while benefiting from shared security.

For teams building blockchain infrastructure that demands institutional-grade reliability, BlockEden.xyz's RPC services provide the low-latency, high-uptime connectivity that production applications require—whether you're deploying on established chains today or preparing for next-generation networks like Zero.

The Road to Fall 2026

Zero's fall 2026 launch gives LayerZero Labs eight months to deliver on extraordinary promises. Key milestones to watch:

Testnet performance: Can the heterogeneous architecture actually sustain 2 million TPS under adversarial conditions? Jolt's ZK proving must demonstrate real-time finality at scale, not in controlled demos.

Validator decentralization: Consumer-grade hardware accessibility is critical to Zero's security model. If validation concentrates among institutions with resources to optimize infrastructure, the permissionless ethos weakens.

Regulatory engagement: DTCC and ICE's participation assumes blockchain settlement aligns with securities regulations. Clarity on tokenized asset frameworks, custody standards, and cross-border transactions will determine whether Zero handles real capital flows or remains a sandbox.

Developer adoption: Institutional backing attracts attention, but developers drive network effects. Zero must demonstrate that its zones offer meaningful advantages over deploying to existing high-performance chains.

Interoperability resilience: Cross-chain bridges are crypto's most attacked infrastructure. LayerZero's DVN security model must prove robust against exploits that have drained billions from competitor protocols.

The Bigger Picture: Finance Meets Programmability

Cathie Wood's "multi-decade shift" framing is apt. Zero's announcement represents more than a blockchain launch—it's a signal that Wall Street's core infrastructure providers now view permissionless, programmable blockchains as the future of finance.

When DTCC explores blockchain settlement, it's not digitizing existing workflows—it's reconceiving what settlement infrastructure could be. Real-time clearing. Tokenized collateral moving frictionlessly across counterparties. Smart contracts automating margin calls and position reconciliation. These capabilities don't just make finance faster; they enable entirely new market structures.

When ICE prepares for 24/7 trading, it's not just extending hours—it's acknowledging that global markets don't sleep, and the constraints of physical trading floors no longer apply.

When Google Cloud enables AI agent micropayments, it's recognizing that the future economy includes machine participants executing millions of micro-transactions that traditional payment rails can't support.

Zero is the infrastructure bet that these use cases demand institutional-grade throughput, finality, and interoperability—capabilities that, until now, no blockchain could credibly claim.

Conclusion

LayerZero's Zero Network is the most explicit convergence of Wall Street and Web3 infrastructure to date. With 2 million TPS capacity, heterogeneous architecture, and partnerships spanning Citadel Securities to Google Cloud, it positions itself as the blockchain backbone for tokenized finance.

Whether Zero succeeds depends on execution. Ambitious TPS claims must withstand production loads. Institutional partnerships must translate to real capital flows. And the blockchain must prove it can maintain security and decentralization while serving institutions accustomed to five-nines uptime and microsecond latencies.

But the direction is unmistakable: finance is moving on-chain, and the world's largest financial institutions are betting that high-performance, interoperable, heterogeneous blockchains are how it gets there.

Zero's fall 2026 launch will be a defining moment—not just for LayerZero, but for the broader question of whether blockchain infrastructure can meet institutional finance's uncompromising standards.

Bitcoin L2 Reality Check: When 75+ Projects Meet a 74% TVL Collapse

· 11 min read
Dora Noda
Software Engineer

The Bitcoin Layer 2 narrative promised to transform BTC from "digital gold" into a programmable financial base layer. With 75+ active projects and ambitious projections of $50 billion TVL by year-end, BTCFi appeared poised for institutional adoption. Then reality struck: Bitcoin L2 TVL collapsed 74% in 2026, while Babylon Protocol alone captures $4.95 billion—representing more than half the entire Bitcoin DeFi ecosystem. Only 0.46% of Bitcoin's circulating supply participates in these protocols.

This isn't just another crypto market correction. It's a reckoning that separates infrastructure building from incentive-driven speculation.

The Great Bitcoin L2 Contraction

Bitcoin DeFi TVL stands at approximately $7 billion in early 2026, down 23% from its October 2025 peak of $9.1 billion. More dramatically, Bitcoin L2 TVL specifically shrank by over 74% this year, declining from a cumulative 101,721 BTC to just 91,332 BTC—a mere 0.46% of all Bitcoin in circulation.

For context, Ethereum's Layer 2 ecosystem commands over $30 billion in TVL across dozens of projects. Bitcoin's entire L2 landscape barely reaches one-quarter of that figure, despite having more projects (75+ vs. Ethereum's major L2s).

The numbers reveal an uncomfortable truth: most Bitcoin L2s are ghost towns shortly after their airdrop farming cycles end. The 2026 Layer 2 Outlook from The Block confirms this pattern, noting that "most new L2s saw usage collapse after incentive cycles" while "only a small handful of L2s have managed to escape this phenomenon."

Babylon's $4.95 Billion Dominance

While the broader Bitcoin L2 ecosystem struggles, Babylon Protocol stands as a towering exception. With $4.95 billion in TVL, Babylon represents approximately 70% of the entire Bitcoin DeFi market. The protocol has secured over 57,000 bitcoins from more than 140,020 unique stakers, accounting for 80% of the Bitcoin ecosystem's overall TVL.

Babylon's dominance stems from solving Bitcoin's fundamental limitation: enabling staking rewards without altering Bitcoin's core protocol. Through its innovative approach, Bitcoin holders can stake their assets to secure Proof-of-Stake chains while maintaining self-custody—no bridges, no wrapped tokens, no custody risk.

The April 2025 launch of Babylon's Genesis layer-1 blockchain marked the second phase of its roadmap, introducing multichain Bitcoin staking across over 70 blockchains. Liquid Staking Tokens (LSTs) emerged as a killer feature, allowing BTC exposure and liquidity while participating in yield protocols—addressing the "productive asset" narrative that Bitcoin L2 builders champion.

Babylon's closest competitor, Lombard, holds approximately $1 billion in TVL—one-fifth of Babylon's dominance. The gap illustrates winner-take-most dynamics in Bitcoin DeFi, where network effects and trust accumulate with established players.

The 75+ Project Fragmentation Problem

Galaxy's research shows Bitcoin L2 projects rising "over sevenfold from 10 to 75" since 2021, with approximately 335 total known implementations or proposals. This proliferation creates a fragmented landscape where dozens of projects compete for the same limited pool of Bitcoin willing to leave cold storage.

The major players adopt radically different technical approaches:

Citrea uses ZK Rollup architecture with "execution slices" that batch-process thousands of transactions, validated on Bitcoin mainnet using compact zero-knowledge proofs. Its BitVM2-based native bridge "Clementine" launched with mainnet on January 27, 2026, positioning Citrea as ZK-first infrastructure for Bitcoin lending, trading, and settlement.

Rootstock (RSK) operates as a sidechain running an EVM-compatible environment, secured by Bitcoin miners through its Powpeg multi-signature mechanism. Users bridge BTC into Rootstock to interact with DeFi protocols, DEXs, and lending markets—a proven but centralized trust model.

Stacks ties its security directly to Bitcoin through its Proof-of-Transfer consensus, rewarding miners via BTC commitments. Post-Nakamoto upgrade, Stacks enables high-velocity smart contracts while maintaining Bitcoin finality.

Mezo raised $21 million in Series A funding—the highest among Bitcoin L2s—to build "Bitcoin-native financial infrastructure" bridging blockchain, DeFi, traditional finance, and real-world applications.

BOB, Bitlayer, and B² Network represent the rollup-centric approach, using optimistic or ZK-rollup architectures to scale Bitcoin transactions while anchoring security to the base layer.

Despite this technical diversity, most projects face the same existential challenge: why should Bitcoin holders bridge their assets to unproven networks? Ethereum L2s benefit from a mature DeFi ecosystem with billions in liquidity. Bitcoin L2s must convince users to move their "digital gold" into experimental protocols with limited track records.

The Programmable Bitcoin Vision vs. Market Reality

Bitcoin L2 builders pitch a compelling vision: transforming Bitcoin from a passive store of value into a productive financial base layer. Leaders from Citrea, Rootstock Labs, and BlockSpaceForce argue that Bitcoin's scaling layers are less about raw throughput and more about "making Bitcoin a productive asset by introducing existing narratives like DeFi, lending, borrowing, and adding that stack to Bitcoin."

The institutional unlock narrative centers on Bitcoin ETFs and institutional custody enabling programmatic interaction with BTCFi protocols. With Bitcoin ETF assets exceeding $125 billion in AUM, even a 5% allocation to Bitcoin L2 protocols would inject $6+ billion in TVL—nearly matching Babylon's current dominance alone.

Yet market reality tells a different story. Core Chain ($660M+ TVL) and Stacks lead the market by leveraging Bitcoin's security while enabling smart contracts, but their combined TVL barely exceeds $1 billion. The remaining 70+ projects split the scraps—most holding less than $50 million each.

The 0.46% circulation penetration rate reveals Bitcoin holders' deep skepticism about bridging their assets. Compare this to Ethereum, where over 30% of ETH participates in staking, liquid staking derivatives, or DeFi protocols. Bitcoin's cultural identity as "digital gold" creates psychological resistance to yield-generating schemes that introduce smart contract risk.

What Separates Winners from Noise

Babylon's success offers clear lessons for distinguishing signal from noise in the Bitcoin L2 landscape:

1. Security-First Architecture: Babylon's self-custodial staking model eliminates bridge risk—the Achilles' heel of most L2s. Users maintain control of their private keys while earning yields, aligning with Bitcoin's ethos of trustless systems. By contrast, projects requiring wrapped BTC or custodial bridges inherit massive security attack surfaces.

2. Real Utility Beyond Speculation: Babylon enables Bitcoin to secure 70+ Proof-of-Stake chains, creating genuine demand for BTC staking beyond speculative yield farming. This utility-driven model contrasts with L2s offering DeFi primitives (lending, DEXs) that Ethereum already provides with deeper liquidity and better UX.

3. Capital Efficiency: Liquid Staking Tokens allow staked Bitcoin to remain productive across DeFi applications, multiplying capital efficiency. Projects lacking LST equivalents force users to choose between staking yields and DeFi participation—a losing proposition against Ethereum's mature LST ecosystem (Lido, Rocket Pool, etc.).

4. Network Effects and Trust: Babylon's $4.95 billion TVL attracts institutional attention, creating a flywheel where liquidity begets liquidity. Smaller L2s face chicken-and-egg problems: developers won't build without users, users won't come without applications, and liquidity providers demand both.

The harsh reality: most Bitcoin L2s lack differentiated value propositions. Offering "EVM compatibility on Bitcoin" or "faster transaction speeds" misses the point—Ethereum L2s already provide these features with vastly superior ecosystems. Bitcoin L2s must answer: What can only be built on Bitcoin?

The Path Forward: Consolidation or Extinction

Optimistic projections suggest Bitcoin L2 TVL could reach $50 billion by year-end 2026, fueled by Bitcoin ETF adoption and maturing infrastructure. Some analysts forecast $200 billion by 2027 if bull market conditions persist. These scenarios require a 7x-10x increase from current levels—possible only through consolidation around winning protocols.

The likely outcome mirrors Ethereum's L2 shakeout: Base, Arbitrum, and Optimism capture 90% of L2 transaction volume, while dozens of "zombie chains" fade into irrelevance. Bitcoin L2s face similar winner-take-most dynamics.

Babylon has already established itself as the Bitcoin staking standard. Its multichain approach and LST ecosystem create defensible moats against competitors.

Citrea and Stacks represent the ZK-rollup and sidechain archetypes, respectively. Both have sufficient funding, technical credibility, and ecosystem partnerships to survive—but capturing market share from Babylon remains uncertain.

Mezo's $21 million Series A signals investor conviction in Bitcoin-native financial infrastructure. Its focus on bridging TradFi and DeFi could unlock institutional capital flows that pure-play crypto projects cannot access.

The remaining 70+ projects face existential questions. Without differentiated technology, institutional partnerships, or killer applications, they risk becoming footnotes in Bitcoin's history—victims of their own incentive-driven hype cycles.

The Institutional Bitcoin DeFi Thesis

For Bitcoin L2s to achieve their $50+ billion TVL targets, institutional adoption must accelerate dramatically. The building blocks are emerging:

Bitcoin ETF Programmability: Spot Bitcoin ETFs hold over $125 billion in assets. As custodians like Fidelity, BlackRock, and Coinbase develop programmatic access to Bitcoin DeFi protocols, institutional capital could flow into vetted L2s offering compliant yield products.

Regulatory Clarity: The GENIUS Act and evolving stablecoin regulations provide clearer frameworks for institutional participation in crypto. Bitcoin's established regulatory status as a commodity (not a security) positions BTCFi favorably compared to altcoin DeFi.

Risk-Adjusted Yields: Babylon's 4-7% staking yields on Bitcoin—without smart contract risk from wrapped tokens—offer compelling risk-adjusted returns for institutional treasuries. As adoption grows, these yields could normalize traditional Bitcoin's "zero yield" narrative.

Infrastructure Maturation: Chainlink's Proof of Reserve for BTCFi, institutional-grade custody integrations, and insurance products (from Nexus Mutual, Unslashed, etc.) reduce institutional barriers to Bitcoin DeFi participation.

The institutional thesis hinges on Bitcoin L2s becoming compliant, audited, insured infrastructure—not speculative yield farms. Projects building toward regulated institutional rails have survival potential. Those chasing retail airdrop farmers do not.

Whether you're launching a BTCFi protocol or integrating Bitcoin data into your application, explore our Bitcoin API services designed for reliability and performance at scale.

Conclusion: The 2026 Bitcoin L2 Reckoning

The 74% Bitcoin L2 TVL collapse exposes the gap between ambitious narratives and market fundamentals. With 75+ projects competing for just 0.46% of Bitcoin's circulating supply, the vast majority of Bitcoin L2s exist as speculative infrastructure without sustainable demand.

Babylon's $4.95 billion dominance proves that differentiated value propositions can succeed: self-custodial staking, multichain security, and liquid staking derivatives address real Bitcoin holder needs. The rest of the ecosystem must either consolidate around compelling use cases or face extinction.

The programmable Bitcoin vision remains valid—institutional Bitcoin ETFs, maturing infrastructure, and regulatory clarity create long-term tailwinds. But 2026's reality check demonstrates that Bitcoin holders won't bridge their assets to unproven protocols without security guarantees, genuine utility, and compelling risk-adjusted returns.

The Bitcoin L2 landscape will consolidate dramatically. A handful of winners (Babylon, likely Citrea and Stacks, possibly Mezo) will capture 90%+ of TVL. The remaining 70+ projects will fade as incentive programs end and users return their Bitcoin to cold storage.

For builders and investors, the lesson is clear: in Bitcoin DeFi, security and utility trump speed and hype. The projects that survive won't be those with the flashiest roadmaps—they'll be the ones Bitcoin holders actually trust with their digital gold.

Ethereum's Pectra Mega-Upgrade: Why 11 EIPs Changed Everything for Validators

· 13 min read
Dora Noda
Software Engineer

When Ethereum activated its Pectra upgrade on May 7, 2025, at epoch 364032, it wasn't just another routine hard fork. With 11 Ethereum Improvement Proposals bundled into a single deployment, Pectra represented the network's most ambitious protocol upgrade since The Merge—and the aftershocks are still reshaping how institutions, validators, and Layer-2 rollups interact with Ethereum in 2026.

The numbers tell the story: validator uptime hit 99.2% in Q2 2025, staking TVL surged to $86 billion by Q3, and Layer-2 fees dropped 53%. But beneath these headline metrics lies a fundamental restructuring of Ethereum's validator economics, data availability architecture, and smart account capabilities. Nine months after activation, we're finally seeing the full strategic implications unfold.

The Validator Revolution: From 32 ETH to 2048 ETH

The centerpiece of Pectra—EIP-7251—shattered a constraint that had defined Ethereum staking since the Beacon Chain's genesis: the rigid 32 ETH validator limit.

Before Pectra, institutional stakers running 10,000 ETH faced a logistical nightmare: managing 312 separate validator instances, each requiring distinct infrastructure, monitoring systems, and operational overhead. A single institution might operate hundreds of nodes scattered across data centers, each one demanding continuous uptime, separate signing keys, and individual attestation duties.

EIP-7251 changed the game entirely. Validators can now stake up to 2,048 ETH per validator—a 64x increase—while maintaining the same 32 ETH minimum for solo stakers. This isn't merely a convenience upgrade; it's an architectural pivot that fundamentally alters Ethereum's consensus economics.

Why This Matters for Network Health

The impact extends beyond operational simplicity. Every active validator must sign attestations in each epoch (approximately every 6.4 minutes). With hundreds of thousands of validators, the network processes an enormous volume of signatures—creating bandwidth bottlenecks and increasing latency.

By allowing consolidation, EIP-7251 reduces the total validator count without sacrificing decentralization. Large operators consolidate stakes, but solo stakers still participate with 32 ETH minimums. The result? Fewer signatures per epoch, reduced consensus overhead, and improved network efficiency—all while preserving Ethereum's validator diversity.

For institutions, the economics are compelling. Managing 312 validators requires significant DevOps resources, backup infrastructure, and slashing risk mitigation strategies. Consolidating to just 5 validators running 2,048 ETH each slashes operational complexity by 98% while maintaining the same earning power.

Execution Layer Withdrawals: Fixing Staking's Achilles Heel

Before Pectra, one of Ethereum staking's most underappreciated risks was the rigid withdrawal process. Validators could only trigger exits through consensus layer operations—a design that created security vulnerabilities for staking-as-a-service platforms.

EIP-7002 introduced execution layer triggerable withdrawals, fundamentally changing the security model. Now, validators can initiate exits directly from their withdrawal credentials on the execution layer, bypassing the need for consensus layer key management.

This seemingly technical adjustment has profound implications for staking services. Previously, if a node operator's consensus layer keys were compromised or if the operator went rogue, stakers had limited recourse. With execution layer withdrawals, the withdrawal credential holder retains ultimate control—even if validator keys are breached.

For institutional custodians managing billions in staked ETH, this separation of concerns is critical. Validator operations can be delegated to specialized node operators, while withdrawal control remains with the asset owner. It's the staking equivalent of separating operational authority from treasury control—a distinction that traditional financial institutions demand.

The Blob Capacity Explosion: Rollups Get 50% More Room

While validator changes grabbed headlines, EIP-7691's blob capacity increase may prove equally transformative for Ethereum's scaling trajectory.

The numbers: blob targets increased from 3 to 6 per block, with maximums rising from 6 to 9. Post-activation data confirms the impact—daily blobs jumped from approximately 21,300 to 28,000, translating to 3.4 gigabytes of blob space compared to 2.7 GB before the upgrade.

For Layer-2 rollups, this represents a 50% increase in data availability bandwidth at a time when Base, Arbitrum, and Optimism collectively process over 90% of Ethereum's L2 transaction volume. More blob capacity means rollups can settle more transactions to Ethereum's mainnet without bidding up blob fees—effectively expanding Ethereum's total throughput capacity.

But the fee dynamics are equally important. EIP-7691 recalibrated the blob base fee formula: when blocks are full, fees rise approximately 8.2% per block (less aggressive than before), while during periods of low demand, fees decrease roughly 14.5% per block (more aggressive). This asymmetric adjustment mechanism ensures that blob space remains affordable even as usage scales—a critical design choice for rollup economics.

The timing couldn't be better. With Ethereum rollups processing billions in daily transaction volume and competition intensifying among L2s, expanded blob capacity prevents a data availability crunch that could have choked scaling progress in 2026.

Faster Validator Onboarding: From 12 Hours to 13 Minutes

EIP-6110's impact is measured in time—specifically, the dramatic reduction in validator activation delays.

Previously, when a new validator submitted a 32 ETH deposit, the consensus layer waited for the execution layer to finalize the deposit transaction, then processed it through the beacon chain's validator queue—a process requiring approximately 12 hours on average. This delay created friction for institutional stakers seeking to deploy capital quickly, especially during market volatility when staking yields become more attractive.

EIP-6110 moved validator deposit processing entirely onto the execution layer, reducing activation time to roughly 13 minutes—a 98% improvement. For large institutions deploying hundreds of millions in ETH during strategic windows, hours of delay translate directly to opportunity cost.

The activation time improvement also matters for validator set responsiveness. In a proof-of-stake network, the ability to onboard validators quickly enhances network agility—allowing the validator pool to expand rapidly during periods of high demand and ensuring that Ethereum's security budget scales with economic activity.

Smart Accounts Go Mainstream: EIP-7702's Wallet Revolution

While staking upgrades dominated technical discussions, EIP-7702 may have the most profound long-term impact on user experience.

Ethereum's wallet landscape has long been divided between Externally Owned Accounts (EOAs)—traditional wallets controlled by private keys—and smart contract wallets offering features like social recovery, spending limits, and multi-signature controls. The problem? EOAs couldn't execute smart contract logic, and converting an EOA to a smart contract required migrating funds to a new address.

EIP-7702 introduces a new transaction type that lets EOAs temporarily delegate execution to smart contract bytecode. In practical terms, your standard MetaMask wallet can now behave like a full smart contract wallet for a single transaction—executing complex logic like batched operations, gas payment delegation, or conditional transfers—without permanently converting to a contract address.

For developers, this unlocks "smart account" functionality without forcing users to abandon their existing wallets. A user can sign a single transaction that delegates execution to a contract, enabling features like:

  • Batched transactions: Approve a token and execute a swap in one action
  • Gas sponsorship: DApps pay gas fees on behalf of users
  • Session keys: Grant temporary permissions to applications without exposing master keys

The backward compatibility is crucial. EIP-7702 doesn't replace account abstraction efforts (like EIP-4337); instead, it provides an incremental path for EOAs to access smart account features without ecosystem fragmentation.

Testnet Turbulence: The Hoodi Solution

Pectra's path to mainnet wasn't smooth. Initial testnet deployments on Holesky and Sepolia encountered finality issues that forced developers to pause and diagnose.

The root cause? A misconfiguration in deposit contract addresses threw off the Pectra requests hash calculation, generating incorrect values. Majority clients like Geth stalled completely, while minority implementations like Erigon and Reth continued processing blocks—exposing client diversity vulnerabilities.

Rather than rushing a flawed upgrade to mainnet, Ethereum developers launched Hoodi, a new testnet specifically designed to stress-test Pectra's edge cases. This decision, while delaying the upgrade by several weeks, proved critical. Hoodi successfully identified and resolved the finality issues, ensuring mainnet activation proceeded without incident.

The episode reinforced Ethereum's commitment to "boring" pragmatism over hype-driven timelines—a cultural trait that distinguishes the ecosystem from competitors willing to sacrifice stability for speed.

The 2026 Roadmap: Fusaka and Glamsterdam

Pectra wasn't designed to be Ethereum's final form—it's a foundation for the next wave of scaling and security upgrades arriving in 2026.

Fusaka: Data Availability Evolution

Expected in Q4 2025 (launched successfully), Fusaka introduced PeerDAS (Peer Data Availability Sampling), a mechanism enabling nodes to verify data availability without downloading entire blobs. By allowing light clients to sample random blob chunks and statistically verify availability, PeerDAS dramatically reduces bandwidth requirements for validators—a prerequisite for further blob capacity increases.

Fusaka also continued Ethereum's "incremental improvement" philosophy, delivering targeted upgrades rather than monolithic overhauls.

Glamsterdam: Parallel Processing Arrives

The big event for 2026 is Glamsterdam (mid-year), which aims to introduce parallel transaction execution and enshrined proposer-builder separation (ePBS).

Two key proposals:

  • EIP-7732 (ePBS): Separates block proposals from block building at the protocol level, increasing transparency in MEV flows and reducing centralization risks. Instead of validators building blocks themselves, specialized builders compete to produce blocks while proposers simply vote on the best option—creating a market for block production.

  • EIP-7928 (Block-level Access Lists): Enables parallel transaction processing by declaring which state elements each transaction will access. This allows validators to execute non-conflicting transactions simultaneously, dramatically increasing throughput.

If successful, Glamsterdam could push Ethereum toward the oft-cited "10,000 TPS" target—not through a single breakthrough, but through Layer-1 efficiency gains that compound with Layer-2 scaling.

Following Glamsterdam, Hegota (late 2026) will focus on interoperability, privacy enhancements, and rollup maturity—consolidating the work of Pectra, Fusaka, and Glamsterdam into a cohesive scaling stack.

Institutional Adoption: The Numbers Don't Lie

The proof of Pectra's impact lies in post-upgrade metrics:

  • Staking TVL: $86 billion by Q3 2025, up from $68 billion pre-Pectra
  • Validator uptime: 99.2% in Q2 2025, reflecting improved operational efficiency
  • Layer-2 fees: Down 53% on average, driven by expanded blob capacity
  • Validator consolidation: Early data suggests large operators reduced validator counts by 40-60% while maintaining stake levels

Perhaps most telling, institutional staking services like Coinbase, Kraken, and Lido reported significant decreases in operational overhead post-Pectra—costs that directly impact retail staking yields.

Fidelity Digital Assets noted in their Pectra analysis that the upgrade "addresses practical challenges that had limited institutional participation," specifically citing faster onboarding and improved withdrawal security as critical factors for regulated entities.

What Developers Need to Know

For developers building on Ethereum, Pectra introduces both opportunities and considerations:

EIP-7702 Wallet Integration: Applications should prepare for users with enhanced EOA capabilities. This means designing interfaces that can detect EIP-7702 support and offering features like batched transactions and gas sponsorship.

Blob Optimization: Rollup developers should optimize calldata compression and blob posting strategies to maximize the 50% capacity increase. Efficient blob usage directly translates to lower L2 transaction costs.

Validator Operations: Staking service providers should evaluate consolidation strategies. While 2,048 ETH validators reduce operational complexity, they also concentrate slashing risk—requiring robust key management and uptime monitoring.

Future-Proofing: With Glamsterdam's parallel execution on the horizon, developers should audit smart contracts for state access patterns. Contracts that can declare state dependencies upfront will benefit most from parallel processing.

The Bigger Picture: Ethereum's Strategic Position

Pectra solidifies Ethereum's position not through dramatic pivots, but through disciplined incrementalism.

While competitors tout headline-grabbing TPS numbers and novel consensus mechanisms, Ethereum focuses on unsexy fundamentals: validator economics, data availability, and backward-compatible UX improvements. This approach sacrifices short-term narrative excitement for long-term architectural soundness.

The strategy shows in market adoption. Despite a crowded Layer-1 landscape, Ethereum's rollup-centric scaling vision continues to attract the majority of developer activity, institutional capital, and real-world DeFi volume. Base, Arbitrum, and Optimism collectively process billions in daily transactions—not because Ethereum's base layer is the fastest, but because its data availability guarantees and security assurances make it the most credible settlement layer.

Pectra's 11 EIPs don't promise revolutionary breakthroughs. Instead, they deliver compounding improvements: validators operate more efficiently, rollups scale more affordably, and users access smarter account features—all without breaking existing infrastructure.

In an industry prone to boom-bust cycles and paradigm shifts, boring reliability might be Ethereum's greatest competitive advantage.

Conclusion

Nine months after activation, Pectra's legacy is clear: it transformed Ethereum from a proof-of-stake network with scaling ambitions into a scalable proof-of-stake network with institutional-grade infrastructure.

The 64x increase in validator stake capacity, sub-15-minute activation times, and 50% blob capacity expansion don't individually represent moonshots—but together, they remove the friction points that had constrained Ethereum's institutional adoption and Layer-2 scaling potential.

As Fusaka's PeerDAS and Glamsterdam's parallel execution arrive in 2026, Pectra's foundation will prove critical. You can't build 10,000 TPS on a validator architecture designed for 32 ETH stakes and 12-hour activation delays.

Ethereum's roadmap remains long, complex, and decidedly unsexy. But for developers building the next decade of decentralized finance, that pragmatic incrementalism—choosing boring reliability over narrative flash—may be exactly what production systems require.

Ethereum's Pectra Upgrade: A New Era of Scalability and Efficiency

· 12 min read
Dora Noda
Software Engineer

When Ethereum activated the Prague-Electra (Pectra) upgrade on May 7, 2025, it marked the network's most comprehensive transformation since The Merge. With 11 Ethereum Improvement Proposals (EIPs) deployed in a single coordinated hard fork, Pectra fundamentally reshaped how validators stake, how data flows through the network, and how Ethereum positions itself for the next phase of scaling.

Nine months into the Pectra era, the upgrade's impact is measurable: rollup fees on Base, Arbitrum, and Optimism have dropped 40–60%, validator consolidation reduced network overhead by thousands of redundant validators, and the foundation for 100,000+ TPS is now in place. But Pectra is just the beginning—Ethereum's new biannual upgrade schedule (Glamsterdam in mid-2026, Hegota in late 2026) signals a strategic shift from mega-upgrades to rapid iteration.

For blockchain infrastructure providers and developers building on Ethereum, understanding Pectra's technical architecture isn't optional. This is the blueprint for how Ethereum will scale, how staking economics will evolve, and how the network will compete in an increasingly crowded Layer 1 landscape.

The Stakes: Why Pectra Mattered

Before Pectra, Ethereum faced three critical bottlenecks:

Validator inefficiency: Solo stakers and institutional operators alike were forced to run multiple 32 ETH validators, creating network bloat. With over 1 million validators pre-Pectra, each new validator added P2P message overhead, signature aggregation costs, and memory footprint to the BeaconState.

Staking rigidity: The 32 ETH validator model was inflexible. Large operators couldn't consolidate, and stakers couldn't earn compounding rewards on excess ETH above 32. This forced institutional players to manage thousands of validators—each requiring separate signing keys, monitoring, and operational overhead.

Data availability constraints: Ethereum's blob capacity (introduced in the Dencun upgrade) was capped at 3 target/6 maximum blobs per block. As Layer 2 adoption accelerated, data availability became a chokepoint, pushing blob base fees higher during peak demand.

Pectra solved these challenges through a coordinated upgrade of both execution (Prague) and consensus (Electra) layers. The result: a more efficient validator set, flexible staking mechanics, and a data availability layer ready to support Ethereum's rollup-centric roadmap.

EIP-7251: The MaxEB Revolution

EIP-7251 (MaxEB) is the upgrade's centerpiece, raising the maximum effective balance per validator from 32 ETH to 2048 ETH.

Technical Mechanics

Balance Parameters:

  • Minimum activation balance: 32 ETH (unchanged)
  • Maximum effective balance: 2048 ETH (64x increase)
  • Staking increments: 1 ETH (previously required 32 ETH multiples)

This change decouples staking flexibility from network overhead. Instead of forcing a whale staking 2,048 ETH to run 64 separate validators, they can now consolidate into a single validator.

Auto-Compounding: Validators using the new 0x02 credential type automatically compound rewards above 32 ETH, up to the 2,048 ETH maximum. This eliminates the need for manual restaking and maximizes capital efficiency.

Consolidation Mechanism

Validator consolidation allows active validators to merge without exiting. The process:

  1. Source validator is marked as exited
  2. Balance transfers to target validator (must have 0x02 credentials)
  3. No impact on total stake or churn limit

Consolidation Timeline: At current churn rates, consolidating all existing validators would require approximately 21 months—assuming no net inflow from new activations or exits.

Network Impact

Early data shows significant reductions:

  • P2P message overhead: Fewer validators = fewer attestations to propagate
  • Signature aggregation: Reduced BLS signature load per epoch
  • BeaconState memory: Smaller validator registry lowers node resource requirements

However, MaxEB introduces new considerations. Larger effective balances mean proportionally larger slashing penalties. For slashable attestations, the penalty scales with effective_balance to maintain security guarantees around 1/3-slashable events.

Slashing Adjustment: To balance the risk, Pectra reduced the initial slashing amount by 128x—from 1/32 of balance to 1/4096 of effective balance. This prevents disproportionate punishment while maintaining network security.

EIP-7002: Execution Layer Withdrawals

EIP-7002 introduces a smart contract mechanism for triggering validator exits from the execution layer, eliminating the dependency on Beacon Chain validator signing keys.

How It Works

Pre-Pectra, exiting a validator required access to the validator's signing key. If the key was lost, compromised, or held by a node operator in a delegated staking model, stakers had no recourse.

EIP-7002 deploys a new contract that allows withdrawals to be triggered using execution layer withdrawal credentials. Stakers can now call a function in this contract to initiate exits—no Beacon Chain interaction required.

Implications for Staking Protocols

This is a game-changer for liquid staking and institutional staking infrastructure:

Reduced trust assumptions: Staking protocols no longer need to fully trust node operators with exit control. If a node operator goes rogue or becomes unresponsive, the protocol can trigger exits programmatically.

Enhanced programmability: Smart contracts can now manage entire validator lifecycles—deposits, attestations, exits, and withdrawals—entirely on-chain. This enables automated rebalancing, slashing insurance mechanisms, and permissionless staking pool exits.

Faster validator management: The delay between submitting a withdrawal request and validator exit is now ~13 minutes (via EIP-6110), down from 12+ hours pre-Pectra.

For liquid staking protocols like Lido, Rocket Pool, and institutional platforms, EIP-7002 reduces operational complexity and enhances user experience. Stakers no longer face the risk of "stuck" validators due to lost keys or uncooperative operators.

EIP-7691: Blob Capacity Expansion

Ethereum's blob-centric scaling model relies on dedicated data availability space for rollups. EIP-7691 doubled blob capacity—from 3 target/6 max to 6 target/9 max blobs per block.

Technical Parameters

Blob Count Adjustment:

  • Target blobs per block: 6 (previously 3)
  • Maximum blobs per block: 9 (previously 6)

Blob Base Fee Dynamics:

  • Blob base fee rises +8.2% per block when capacity is full (previously more aggressive)
  • Blob base fee drops -14.5% per block when blobs are scarce (previously slower decline)

This creates a more stable fee market. When demand spikes, fees rise gradually. When demand drops, fees decrease sharply to attract rollup usage.

Impact on Layer 2s

Within weeks of Pectra activation, rollup fees dropped 40–60% on major L2s:

  • Base: Average transaction fees down 52%
  • Arbitrum: Average fees down 47%
  • Optimism: Average fees down 58%

These reductions are structural, not temporary. By doubling data availability, EIP-7691 gives rollups twice the capacity to post compressed transaction data on Ethereum L1.

2026 Blob Expansion Roadmap

EIP-7691 was the first step. Ethereum's 2026 roadmap includes further aggressive expansions:

BPO-1 (Blob Pre-Optimization 1): Already implemented with Pectra (6 target/9 max)

BPO-2 (January 7, 2026):

  • Target blobs: 14
  • Maximum blobs: 21

BPO-3 & BPO-4 (2026+): Aiming for 128 blobs per block once data from BPO-1 and BPO-2 is analyzed.

The goal: Data availability that scales linearly with rollup demand, keeping blob fees low and predictable while Ethereum L1 remains the settlement and security layer.

The Other 8 EIPs: Rounding Out the Upgrade

While EIP-7251, EIP-7002, and EIP-7691 dominate headlines, Pectra included eight additional improvements:

EIP-6110: On-Chain Validator Deposits

Previously, validator deposits required off-chain tracking to finalize. EIP-6110 brings deposit data on-chain, reducing deposit confirmation time from 12 hours to ~13 minutes.

Impact: Faster validator onboarding, critical for liquid staking protocols handling high deposit volumes.

EIP-7549: Committee Index Optimization

EIP-7549 moves the committee index outside of the signed attestation, reducing attestation size and simplifying aggregation logic.

Impact: More efficient attestation propagation across the P2P network.

EIP-7702: Set EOA Account Code

EIP-7702 allows externally owned accounts (EOAs) to temporarily behave like smart contracts for the duration of a single transaction.

Impact: Account abstraction-like functionality for EOAs without migrating to smart contract wallets. This enables gas sponsorship, batched transactions, and custom authentication schemes.

EIP-2537: BLS12-381 Precompiles

Adds precompiled contracts for BLS signature operations, enabling more efficient cryptographic operations on Ethereum.

Impact: Lower gas costs for applications relying on BLS signatures (e.g., bridges, rollups, zero-knowledge proof systems).

EIP-2935: Historical Block Hash Storage

Stores historical block hashes in a dedicated contract, making them accessible beyond the current 256-block limit.

Impact: Enables trustless verification of historical state for cross-chain bridges and oracles.

EIP-7685: General Purpose Requests

Introduces a generalized framework for execution layer requests to the consensus layer.

Impact: Simplifies future protocol upgrades by standardizing how execution and consensus layers communicate.

EIP-7623: Increase Calldata Cost

Raises the cost of calldata to discourage inefficient data usage and incentivize rollups to use blobs instead.

Impact: Encourages migration from calldata-based rollups to blob-based rollups, improving overall network efficiency.

EIP-7251: Validator Slashing Penalty Adjustment

Reduces correlation slashing penalties to prevent disproportionate punishment under the new MaxEB model.

Impact: Balances the increased slashing risk from larger effective balances.

Ethereum's 2026 Biannual Upgrade Cadence

Pectra signals a strategic shift: Ethereum is abandoning mega-upgrades (like The Merge) in favor of predictable, biannual releases.

Glamsterdam (Mid-2026)

Expected launch: May or June 2026

Key Features:

  • Enshrined Proposer-Builder Separation (ePBS): Separates block building from block proposing at the protocol level, reducing MEV centralization and censorship risks
  • Gas optimizations: Further reductions in gas costs for common operations
  • L1 efficiency improvements: Targeted optimizations to reduce node resource requirements

Glamsterdam focuses on immediate scalability and decentralization wins.

Hegota (Late 2026)

Expected launch: Q4 2026

Key Features:

  • Verkle Trees: Replaces Merkle Patricia trees with Verkle trees, dramatically reducing proof sizes and enabling stateless clients
  • Historical data management: Improves node storage efficiency by allowing nodes to prune old data without compromising security

Hegota targets long-term node sustainability and decentralization.

Fusaka Foundation (December 2025)

Already deployed on December 3, 2025, Fusaka introduced:

  • PeerDAS (Peer Data Availability Sampling): Lays groundwork for 100,000+ TPS by enabling nodes to verify data availability without downloading entire blocks

Together, Pectra, Fusaka, Glamsterdam, and Hegota form a continuous upgrade pipeline that keeps Ethereum competitive without the multi-year gaps of the past.

What This Means for Infrastructure Providers

For infrastructure providers and developers, Pectra's changes are foundational:

Node operators: Expect continued validator consolidation as large stakers optimize for efficiency. Node resource requirements will stabilize as the validator set shrinks, but slashing logic is more complex under MaxEB.

Liquid staking protocols: EIP-7002's execution-layer exits enable programmatic validator management at scale. Protocols can now build trustless staking pools with automated rebalancing and exit coordination.

Rollup developers: Blob fee reductions are structural and predictable. Plan for further blob capacity expansion (BPO-2 in January 2026) and design data posting strategies around the new fee dynamics.

Wallet developers: EIP-7702 opens account abstraction-like features for EOAs. Gas sponsorship, session keys, and batched transactions are now possible without forcing users to migrate to smart contract wallets.

BlockEden.xyz provides enterprise-grade Ethereum node infrastructure with full support for Pectra's technical requirements, including blob transactions, execution-layer validator exits, and high-throughput data availability. Explore our Ethereum API services to build on infrastructure designed for Ethereum's scaling roadmap.

The Road Ahead

Pectra proves that Ethereum's roadmap is no longer theoretical. Validator consolidation, execution-layer withdrawals, and blob scaling are live—and they're working.

As Glamsterdam and Hegota approach, the narrative shifts from "can Ethereum scale?" to "how fast can Ethereum iterate?" The biannual upgrade cadence ensures Ethereum evolves continuously, balancing scalability, decentralization, and security without the multi-year waits of the past.

For developers, the message is clear: Ethereum is the settlement layer for a rollup-centric future. Infrastructure that leverages Pectra's blob scaling, Fusaka's PeerDAS, and the upcoming Glamsterdam optimizations will define the next generation of blockchain applications.

The upgrade is here. The roadmap is clear. Now it's time to build.

Somnia's 2026 Roadmap: How 1M+ TPS Infrastructure is Redefining Real-Time Blockchain Applications

· 14 min read
Dora Noda
Software Engineer

Most blockchains claim to be fast. Somnia proves it by processing over one million transactions per second while enabling something competitors haven't solved: true real-time reactivity onchain. As the blockchain infrastructure race intensifies in 2026, Somnia is betting that raw performance combined with revolutionary data delivery mechanisms will unlock blockchain's most ambitious use cases—from hyper-granular prediction markets to fully onchain metaverses.

The Performance Breakthrough That Changes Everything

When Somnia's DevNet demonstrated 1,000,000+ transactions per second with sub-second finality and fees measured in fractions of a cent, it wasn't just breaking records. It was eliminating the primary excuse developers have used for decades to avoid building fully onchain applications.

The technology stack behind this achievement represents years of innovation from Improbable, the gaming infrastructure company that learned how to scale distributed systems by building virtual worlds. By applying knowledge from gaming and distributed systems engineering, Somnia cracked the scalability problem that has long hindered blockchain technology.

Three core innovations enable this unprecedented performance:

MultiStream Consensus: Instead of processing transactions sequentially, Somnia's novel consensus protocol handles multiple transaction streams in parallel. This architectural shift transforms how blockchains approach throughput—think of it as switching from a single-lane highway to a multi-lane expressway where each lane processes transactions simultaneously.

IceDB Ultra-Low Latency Storage: At the heart of Somnia's speed advantage is IceDB, a custom-built database layer that delivers deterministic reads in 15-100 nanoseconds. This isn't just fast—it's fast enough to enable fair gas pricing based on actual resource usage rather than worst-case estimates. The database ensures every operation executes at predictable speeds, eliminating the performance variance that plagues other blockchains.

Custom EVM Compiler: Somnia doesn't just run standard Ethereum Virtual Machine code—it compiles EVM bytecode for optimized execution. Combined with novel compression algorithms that transfer data up to 20 times more efficiently than competing blockchains, this creates an environment where developers can build complex applications without worrying about gas optimization gymnastics.

The result? A blockchain that can support millions of users running real-time applications entirely onchain—from games to social networks to immersive virtual worlds.

Data Streams: The Infrastructure Revolution Nobody's Talking About

Raw transaction throughput is impressive, but Somnia's most transformative innovation in 2026 may be Data Streams—a fundamentally different approach to how applications consume blockchain data.

Traditional blockchain applications face a frustrating paradox: they need real-time information, but blockchains weren't designed to push data proactively. Developers resort to constant polling (expensive and inefficient), third-party indexers (centralized and costly), or oracles that post periodic updates (too slow for time-sensitive applications). Every solution involves compromises.

Somnia Data Streams eliminates this dilemma by introducing subscription-based RPCs that push updates directly to applications whenever blockchain state changes. Instead of applications repeatedly asking "has anything changed?" they subscribe to specific data streams and receive automatic notifications when relevant state transitions occur.

The architectural shift is profound:

  • No More Polling Overhead: Applications eliminate redundant queries, dramatically reducing infrastructure costs and network congestion.
  • True Real-Time Reactivity: State changes propagate to applications instantly, enabling responsive experiences that feel native rather than blockchain-constrained.
  • Simplified Development: Developers no longer need to build and maintain complex indexing infrastructure—the blockchain handles data delivery natively.

This infrastructure becomes particularly powerful when combined with Somnia's native support for events, timers, and verifiable randomness. Developers can now build reactive applications entirely onchain with the same architectural patterns they use in traditional web2 development, but with blockchain's security and decentralization guarantees.

Somnia Data Streams with full onchain reactivity will be available early next year, with subscription RPCs rolling out first in the coming months. This phased launch allows developers to begin integrating the new paradigm while Somnia fine-tunes the reactive infrastructure for production scale.

The "Market of Markets" Vision for Prediction Markets

Prediction markets have long promised to become the world's most accurate forecasting mechanism, but infrastructure limitations have kept them from reaching full potential. Somnia's 2026 roadmap targets this gap with a bold vision: transform prediction markets from a handful of high-profile events to a "market of markets" where anyone can create hyper-granular, niche prediction markets around virtually any event.

The technical requirements for this vision reveal why existing platforms struggle:

High-Frequency Updates: Sports betting needs second-by-second odds adjustments as games unfold. Esports wagering requires real-time tracking of in-game events. Traditional blockchains can't deliver these updates without prohibitive costs or centralization compromises.

Granular Market Creation: Instead of betting on "who wins the match," imagine wagering on specific performance metrics—which player scores the next goal, which driver completes the fastest lap, or whether a streamer hits a particular viewer milestone in the next hour. Creating and settling thousands of micro-markets requires infrastructure that can handle massive state updates efficiently.

Instant Settlement: When conditions are met, markets should settle immediately without manual intervention or delayed oracle confirmations. This requires native blockchain support for automated condition checking and execution.

Somnia Data Streams solves each challenge:

Applications can subscribe to structured event streams that track real-world occurrences and onchain state simultaneously. When a subscribed event occurs—a goal scored, a lap completed, a threshold crossed—the Data Stream pushes the update instantly. Smart contracts react automatically, updating odds, settling bets, or triggering insurance payouts without human intervention.

The "market of markets" concept extends beyond finance. Gaming studios can track in-game achievements onchain, rewarding players instantly when specific milestones are reached. DeFi protocols can adjust positions in real-time based on market conditions. Insurance products can execute the moment triggering events are verified.

What makes this particularly compelling is the cost structure: sub-cent transaction fees mean creating micro-markets becomes economically viable. A streamer could offer prediction markets on every stream milestone without worrying about gas fees consuming the prize pool. Tournament organizers could run thousands of concurrent betting markets across every match detail.

Somnia is pursuing partnerships and infrastructure development to make this vision operational throughout 2026, positioning itself as the backbone for next-generation prediction market platforms that make traditional sportsbooks look primitive by comparison.

Gaming and Metaverse Infrastructure: Building the Virtual Society

While many blockchains pivot away from gaming narratives when speculative interest wanes, Somnia remains laser-focused on solving the technical challenges that have kept gaming and metaverse applications largely off-chain. The project continues to believe that games will be one of the primary drivers of mainstream blockchain adoption—but only if the infrastructure can actually support the unique demands of large-scale virtual worlds.

The numbers tell the story of why this matters:

Traditional blockchain games compromise constantly. They put critical gameplay elements off-chain because onchain execution is too expensive or too slow. They limit player counts because state synchronization breaks down at scale. They simplify mechanics because complex interactions consume prohibitive gas fees.

Somnia's architecture eliminates these compromises. With 1M+ TPS capacity and sub-second finality, developers can build fully onchain games where:

  • Every Player Action Executes Onchain: No hybrid architectures where combat happens off-chain but loot appears onchain. All game logic, all player interactions, all state updates—everything runs on the blockchain with cryptographic guarantees.

  • Massive Concurrent User Counts: Virtual worlds can support thousands of simultaneous players in shared environments without performance degradation. The MultiStream consensus handles parallel transaction streams from different game regions simultaneously.

  • Complex Real-Time Mechanics: Physics simulations, AI-driven NPCs, dynamic environments—game mechanics that were previously impossible onchain become feasible when transaction costs drop to fractions of a cent and latency measures in milliseconds.

  • Interoperable Game Economies: Items, characters, and progression can move seamlessly between different games and experiences because they're all operating on the same high-performance infrastructure.

The Virtual Society Foundation—the independent organization initiated by Improbable that now stewards Somnia's development—envisions blockchain as the connective tissue linking disparate metaverse experiences into a unified digital economy. Instead of walled-garden virtual worlds owned by individual corporations, Somnia's omnichain protocols enable open, interoperable virtual spaces where value and identity travel with users.

This vision receives substantial backing: the Somnia ecosystem benefits from up to $270 million in combined capital from Improbable, M², and the Virtual Society Foundation, with support from leading crypto investors including a16z, SoftBank, Mirana, SIG, Digital Currency Group, and CMT Digital.

AI Integration: The Third Pillar of Somnia's 2026 Strategy

While Data Streams and prediction markets capture attention, Somnia's 2026 roadmap includes a third strategic element that could prove equally transformative: AI-powered infrastructure for autonomous blockchain agents.

The convergence of AI and blockchain faces a fundamental challenge: AI agents need real-time data access and rapid execution environments to operate effectively, but most blockchains deliver neither. Agents that could theoretically optimize DeFi strategies, manage game economies, or coordinate complex market-making operations get bottlenecked by infrastructure limitations.

Somnia's architecture addresses these limitations directly:

Real-Time Data for AI Decision-Making: Data Streams provide AI agents with instant blockchain state updates, eliminating the lag between onchain events and agent awareness. An AI managing a DeFi position can react to market movements in real-time rather than waiting for periodic oracle updates or polling cycles.

Cost-Effective Agent Execution: Sub-cent transaction fees make it economically viable for AI agents to execute frequent small transactions. Strategies that require dozens or hundreds of micro-adjustments become practical when each action costs fractions of a penny rather than dollars.

Deterministic Low-Latency Operations: IceDB's nanosecond-level deterministic reads ensure AI agents can query state and execute actions with predictable timing—critical for applications where fairness and precision matter.

The reactive capabilities native to Somnia's architecture align particularly well with how modern AI systems operate. Instead of AI agents constantly polling for state changes (expensive and inefficient), they can subscribe to relevant data streams and activate only when specific conditions trigger—event-driven architecture that mirrors best practices in AI system design.

As the blockchain industry moves toward autonomous agent economies in 2026, infrastructure that supports high-frequency AI operations at minimal cost could become a decisive competitive advantage. Somnia is positioning itself to be that infrastructure.

The Ecosystem Taking Shape

Technical capabilities mean little without developers building on them. Somnia's 2026 roadmap emphasizes ecosystem development alongside infrastructure deployment, with several early indicators suggesting traction:

Developer Tooling: Full EVM compatibility means Ethereum developers can port existing contracts and applications to Somnia without rewriting code. The familiar development environment lowers adoption barriers while the performance advantages provide immediate incentive to migrate or deploy multi-chain.

Partnership Strategy: Rather than competing directly with every application vertical, Somnia is pursuing partnerships with specialized platforms in gaming, prediction markets, and DeFi. The goal is positioning Somnia as infrastructure that enables applications to scale beyond what competing chains can support.

Capital Allocation: With $270M in ecosystem funding, Somnia can provide grants, investments, and technical support to promising projects. This capital positions the ecosystem to attract ambitious developers willing to push blockchain capabilities to new limits.

The combination of technical readiness and financial resources creates conditions for rapid ecosystem expansion once mainnet launches and Data Streams reach full production capability.

Challenges and Competitive Landscape

Somnia's ambitious roadmap faces several challenges that will determine whether the technology achieves its transformative potential:

Decentralization Questions: Extreme performance often requires centralization trade-offs. While Somnia maintains EVM compatibility and claims blockchain security properties, the MultiStream consensus mechanism is relatively novel. How the network balances performance with genuine decentralization will face scrutiny as adoption grows.

Network Effect Competition: Ethereum L2s like Base, Arbitrum, and Optimism already capture 90% of L2 transaction volume. Solana has demonstrated high-performance blockchain capabilities with established ecosystem traction. Somnia must convince developers that moving to a newer platform justifies abandoning existing network effects and liquidity.

Data Streams Adoption Curve: Subscription-based reactive blockchain data represents a paradigm shift in how developers build applications. Even if technically superior, adoption requires developer education, tooling maturation, and compelling reference implementations that demonstrate advantages over familiar architectures.

Gaming Skepticism: Multiple blockchain platforms have promised to revolutionize gaming, yet most crypto games struggle with retention and engagement. Somnia must deliver not just infrastructure but actual compelling gaming experiences that prove onchain gaming can compete with traditional titles.

Market Timing: Launching ambitious infrastructure during periods of reduced crypto market enthusiasm tests whether product-market fit exists beyond speculative frenzies. If Somnia can attract serious builders and users in a down market, it validates the value proposition.

What This Means for Blockchain Infrastructure in 2026

Somnia's roadmap represents more than one platform's technical evolution—it signals where blockchain infrastructure competition is heading as the industry matures.

The days of raw TPS numbers as primary differentiators are ending. Somnia achieves 1M+ TPS not as a marketing stunt but as the foundation for enabling application categories that couldn't exist on slower infrastructure. Performance becomes table stakes for the next generation of blockchain platforms.

More importantly, Somnia's Data Streams initiative points toward a future where blockchains compete on developer experience and application enablement rather than just protocol-level metrics. The platform that makes it easiest to build responsive, user-friendly applications will attract developers regardless of whether it offers the absolute highest theoretical throughput.

The "market of markets" vision for prediction markets illustrates how blockchain's next wave focuses on specific use case dominance rather than general-purpose platform status. Instead of trying to be everything to everyone, successful platforms will identify verticals where their unique capabilities provide decisive advantages, then dominate those niches.

AI integration emerging as a strategic priority across Somnia's roadmap reflects broader industry recognition that autonomous agents will become major blockchain users. Infrastructure designed for human-initiated transactions may not optimally serve AI-driven economies. Platforms that architect specifically for agent operations could capture this emerging market segment.

The Bottom Line

Somnia's 2026 roadmap tackles blockchain's most persistent challenges with technology that pushes beyond incremental improvements to architectural reimagination. Whether the platform succeeds in delivering on its ambitious vision depends on execution across multiple fronts: technical deployment of Data Streams infrastructure, ecosystem development to attract compelling applications, and user education to drive adoption of new blockchain interaction paradigms.

For developers building real-time blockchain applications, Somnia offers capabilities unavailable elsewhere—true reactive infrastructure combined with performance that enables fully onchain experiences. For prediction market platforms and gaming studios, the technical specifications align precisely with requirements that existing infrastructure can't meet.

The coming months will reveal whether Somnia's technology can transition from impressive testnet metrics to production deployments that actually unlock new application categories. If Data Streams and reactive infrastructure deliver on their promise, we may look back at 2026 as the year blockchain infrastructure finally caught up to the applications developers have always wanted to build.
