Celestia's Competitive Edge in Data Availability: A Deep Dive
When Ethereum L2s paid $3.83 per megabyte to post data using blobs, Eclipse was paying Celestia $0.07 for the same megabyte. That's not a typo—55 times cheaper, enabling Eclipse to post over 83 GB of data without bankrupting its treasury. This cost differential isn't a temporary market anomaly. It's the structural advantage of purpose-built infrastructure.
Celestia has now processed over 160 GB of rollup data, generates daily blob fees that have grown 10x since late 2024, and commands roughly 50% market share in the data availability sector. The question isn't whether modular data availability works—it's whether Celestia can maintain its lead as EigenDA, Avail, and Ethereum's native blobs compete for the same rollup customers.
Understanding Blob Economics: The Foundation
Before analyzing Celestia's numbers, it's worth understanding what makes data availability economically distinct from other blockchain services.
What Rollups Actually Pay For
When a rollup processes transactions, it produces state changes that need to be verifiable. Rather than trust the rollup operator, users can verify by re-executing transactions against the original data. This requires that transaction data remains available—not forever, but long enough for challenges and verification.
Traditional rollups posted this data directly to Ethereum calldata, paying premium prices for permanent storage on the world's most secure ledger. But most rollup data only needs availability for a challenge window (typically 7-14 days), not eternity. This mismatch created the opening for specialized data availability layers.
Celestia's PayForBlob Model
Celestia's fee model is straightforward: rollups pay per blob based on size and current gas prices. Unlike execution layers where computation costs dominate, data availability is fundamentally about bandwidth and storage—resources that scale more predictably with hardware improvements.
The economics create a flywheel: lower DA costs enable more rollups, more rollups generate more fee revenue, and increased usage justifies infrastructure investment for even greater capacity. Celestia's current throughput of approximately 1.33 MB/s (8 MB blocks every 6 seconds) represents early-stage capacity with a clear path to 100x improvement.
The 160 GB Reality: Who's Using Celestia
The aggregate numbers tell a story of rapid adoption. Over 160 GB of data has been published to Celestia since mainnet launch, with daily data volume averaging around 2.5 GB. But the composition of this data reveals more interesting patterns.
Eclipse: The Volume Leader
Eclipse—a Layer 2 combining Solana's virtual machine with Ethereum settlement—has published over 83 GB of data to Celestia, more than half of all network volume. Eclipse uses Celestia for data availability while settling to Ethereum, demonstrating the modular architecture in practice.
The volume isn't surprising given Eclipse's design choices. Solana Virtual Machine execution generates more data than EVM equivalents, and Eclipse's focus on high-throughput applications (gaming, DeFi, social) means transaction volumes that would be cost-prohibitive on Ethereum DA.
The Enterprise Cohort
Beyond Eclipse, the rollup ecosystem includes:
- Manta Pacific: Over 7 GB posted, an OP Stack rollup focused on ZK applications with Universal Circuits technology
- Plume Network: RWA-specialized L2 using Celestia for tokenized asset transaction data
- Derive: On-chain options and structured products trading
- Aevo: Decentralized derivatives exchange processing high-frequency trading data
- Orderly Network: Cross-chain orderbook infrastructure
Twenty-six rollups now build on Celestia, with major frameworks—Arbitrum Orbit, OP Stack, Polygon CDK—all offering Celestia as a DA option. Rollups-as-a-Service platforms like Conduit and Caldera have made Celestia integration a standard offering.
Fee Revenue Growth
At the end of 2024, Celestia generated approximately $225 per day in blob fees. That number has grown nearly 10x, reflecting both increased usage and the network's ability to capture value as demand rises. The fee market remains early-stage—capacity utilization is low relative to tested limits—but the growth trajectory validates the economic model.
Cost Comparison: Celestia vs. The Competition
Data availability has become a competitive market. Understanding the cost structures helps explain rollup decisions.
Celestia vs. Ethereum Blobs
Ethereum's EIP-4844 (Dencun upgrade) introduced blob transactions, reducing DA costs by 90%+ compared to calldata. But Celestia remains significantly cheaper:
| Metric | Ethereum Blobs | Celestia |
|---|---|---|
| Cost per MB | ~$3.83 | ~$0.07 |
| Cost advantage | Baseline | 55x cheaper |
| Capacity | Limited blob space | 8 MB blocks (scaling to 1 GB) |
For high-volume rollups like Eclipse, this difference is existential. At Ethereum blob prices, Eclipse's 83 GB of data would have cost over $300,000. On Celestia, it cost approximately $6,000.
Celestia vs. EigenDA
EigenDA offers a different value proposition: Ethereum-aligned security through restaking, with claimed throughput of 100 MB/s. The tradeoffs:
| Aspect | Celestia | EigenDA |
|---|---|---|
| Security model | Independent validator set | Ethereum restaking |
| Throughput | 1.33 MB/s (8 MB blocks) | 100 MB/s claimed |
| Architecture | Blockchain-based | Data Availability Committee |
| Decentralization | Public verification | Trust assumptions |
EigenDA's DAC architecture enables higher throughput but introduces trust assumptions that fully blockchain-based solutions avoid. For teams deeply embedded in Ethereum's ecosystem, EigenDA's restaking integration may outweigh Celestia's independence.
Celestia vs. Avail
Avail positions as the most flexible option for multichain applications:
| Aspect | Celestia | Avail |
|---|---|---|
| Cost per MB | Higher | Lower |
| Economic security | Higher | Lower |
| Mainnet capacity | 8 MB blocks | 4 MB blocks |
| Test capacity | 128 MB proven | 128 MB proven |
Avail's lower costs come with lower economic security—a reasonable tradeoff for applications where the marginal cost savings matter more than maximum security guarantees.
The Scaling Roadmap: From 1 MB/s to 1 GB/s
Celestia's current capacity—approximately 1.33 MB/s—is intentionally conservative. The network has demonstrated dramatically higher throughput in controlled testing, providing a clear upgrade path.
Mammoth Testing Results
In October 2024, the Mammoth Mini devnet achieved 88 MB blocks with 3-second block times, delivering approximately 27 MB/s throughput—over 20x current mainnet capacity.
In April 2025, the mamo-1 testnet pushed further: 128 MB blocks with 6-second block times, achieving 21.33 MB/s sustained throughput. This represented 16x current mainnet capacity while incorporating new propagation algorithms like Vacuum! designed for efficient large-block data movement.
Mainnet Upgrade Progress
The scaling is happening incrementally:
- Ginger Upgrade (December 2024): Reduced block times from 12 seconds to 6 seconds
- 8 MB Block Increase (January 2025): Doubled block size via on-chain governance
- Matcha Upgrade (January 2026): Enabled 128 MB blocks through improved propagation mechanics, reducing node storage requirements by 77%
- Lotus Upgrade (July 2025): V4 mainnet release with further TIA holder improvements
The roadmap targets gigabyte-scale blocks by 2030, representing a 1,000x increase from current capacity. Whether market demand grows to justify this capacity remains uncertain, but the technical path is clear.
TIA Tokenomics: How Value Accrues
Understanding Celestia's economics requires understanding TIA's role in the system.
Token Utility
TIA serves three functions:
- Blob fees: Rollups pay TIA for data availability
- Staking: Validators stake TIA to secure the network and earn rewards
- Governance: Token holders vote on network parameters and upgrades
The fee mechanism creates direct linkage between network usage and token demand. As blob submissions increase, TIA is purchased and spent, creating buy pressure proportional to network utility.
Supply Dynamics
TIA launched with 1 billion genesis tokens. Initial inflation was set at 8% annually, decreasing over time toward 1.5% terminal inflation.
The January 2026 Matcha upgrade introduced Proof-of-Governance (PoG), slashing annual token issuance from 5% to 0.25%. This structural change:
- Reduces sell pressure from inflation
- Aligns rewards with governance participation
- Strengthens value capture as network usage grows
Additionally, the Celestia Foundation announced a $62.5 million TIA buyback program in 2025, further reducing circulating supply.
Validator Economics
Effective January 2026, maximum validator commission increased from 10% to 20%. This addresses validators' rising operational expenses—particularly as block sizes grow—while maintaining competitive staking yields.
The Competitive Moat: First-Mover or Sustainable Advantage?
Celestia's 50% DA market share and 160+ GB of posted data represent clear traction. But moats in infrastructure can erode quickly.
Advantages
Framework Integration: Every major rollup framework—Arbitrum Orbit, OP Stack, Polygon CDK—supports Celestia as a DA option. This integration creates switching costs and reduces friction for new rollups.
Proven Scale: The 128 MB block testing provides confidence in future capacity that competitors haven't demonstrated at the same level.
Economic Alignment: The Proof-of-Governance tokenomics and buyback programs create stronger value capture than alternative models.
Challenges
EigenDA's Ethereum Alignment: For teams prioritizing Ethereum-native security, EigenDA's restaking model may be more attractive despite architectural trade-offs.
Avail's Cost Advantage: For cost-sensitive applications, Avail's lower fees may outweigh security differences.
Ethereum's Native Improvement: If Ethereum expands blob capacity significantly (as proposed in various roadmap discussions), the cost differential shrinks.
The Ecosystem Lock-in Question
Celestia's real moat may be ecosystem lock-in. Eclipse's 83+ GB of data creates path dependency—migrating to a different DA layer would require significant infrastructure changes. As more rollups accumulate history on Celestia, switching costs increase.
What the Data Tells Us
Celestia's blob economics validate the modular thesis: specialized infrastructure for data availability can be dramatically cheaper than general-purpose L1 solutions. The 55x cost advantage over Ethereum blobs isn't magic—it's the result of purpose-built architecture optimized for a specific function.
The 160+ GB of posted data proves market demand exists. The 10x growth in fee revenue demonstrates value capture. The scaling roadmap provides confidence in future capacity.
For rollup developers, the calculus is straightforward: Celestia offers the best-tested, most integrated DA solution with a clear path to gigabyte-scale capacity. EigenDA makes sense for Ethereum-native projects willing to accept DAC trust assumptions. Avail serves multichain applications prioritizing flexibility over maximum security.
The data availability market has room for multiple winners serving different segments. But Celestia's combination of proven scale, deep integrations, and improving tokenomics positions it well for the coming wave of rollup expansion.
