The numbers are stark, and they tell a story I’m still trying to process as someone who’s been building L2 infrastructure for six years.
Base now controls 46.58% of all Layer 2 DeFi TVL with $4.63 billion locked in the protocol. That’s nearly half the entire L2 ecosystem. Add Arbitrum’s 30.86%, and you’re looking at 77% of the L2 market controlled by just two networks. The top three—Base, Arbitrum, and Optimism—process nearly 90% of all Layer 2 transactions, with Base alone handling over 60%.
Even more telling: Base captured 62% of total L2 revenue year-to-date in 2025 ($75.4M out of $120.7M total). Meanwhile, 40+ other rollups are fighting over the remaining scraps, and most saw their TVL stagnate or decline once incentive programs faded.
The Distribution Advantage
Here’s what I keep coming back to: Coinbase had 9.3 million monthly active trading users in Q3 2025. Base didn’t need to bootstrap a user base from scratch or run unsustainable liquidity mining programs. Every Coinbase user became a potential Base user through seamless UI integration, verified wallet infrastructure, and fiat on-ramps that competitors simply cannot replicate.
Other L2s are stuck in a painful loop: attract users with incentives → users farm rewards → incentives end → users leave → TVL collapses. Base bypassed this entirely through direct access to an already-onboarded user base.
The Technology Question
This is where it gets uncomfortable for me as an engineer. Many of the L2s that failed to gain traction had equal or superior technology. Better proof systems, lower latency, more innovative approaches to sequencing, novel solutions to MEV. The OP Stack that Base runs on is solid, but it’s not categorically better than zkSync’s zkEVM architecture or StarkNet’s Cairo-based proving system.
The market didn’t select for the best technology. It selected for the best distribution.
Did Rollups Scale Ethereum?
When Vitalik outlined the rollup-centric roadmap, the vision was elegant: anyone can deploy a rollup, innovation happens permissionlessly, Ethereum scales through a thousand flowers blooming. And technically, that happened. We have 50+ rollups in production. Deploying a rollup has never been easier.
But permissionless deployment didn’t lead to decentralized usage. Instead, we got a power-law distribution where one company’s rollup—backed by one company’s 100 million user distribution channel—captured nearly half the market.
From a pure scaling perspective, yes, Ethereum can now process far more transactions than the base layer alone. Base is genuinely settling massive transaction volume to Ethereum mainnet.
But from a decentralization perspective, did we just recreate the centralization problem we were trying to solve? If 77% of L2 activity runs through two entities, and one of those entities controls 46% alone, what exactly did we decentralize?
What Keeps Me Up at Night
I’ve spent the last three years building rollup infrastructure. I believed the story: build better technology, and users will come. Optimize proving systems, reduce latency, improve UX, lower fees. We did all that. And Base still won.
Not because Base built meaningfully better tech. Because Coinbase had distribution, and distribution beats technology every single time in crypto infrastructure markets.
The uncomfortable question I can’t shake: Should we have seen this coming?
Look at every other crypto infrastructure market:
- Exchanges: Binance, Coinbase, Kraken dominate despite dozens of technically competent competitors
- Wallets: MetaMask captured majority share through early Firefox/Chrome distribution
- Nodes/RPC: Infura and Alchemy control massive market share despite being centralized services
Infrastructure markets in crypto follow the same power-law dynamics as traditional tech: a few winners capture most of the value, distribution and network effects matter more than marginal technical improvements, and late entrants need 10x better solutions just to survive.
We assumed rollups would be different. They’re not.
The Path Forward
I’m genuinely conflicted about what this means for Ethereum’s roadmap. On one hand, rollups did scale Ethereum—we’re processing millions of transactions per day that would be impossible on L1. On the other hand, we created a new centralization vector that concentrates activity around whichever entities control user acquisition.
A few questions I’m wrestling with:
For the Ethereum Foundation: Should there have been more focus on distribution and user acquisition alongside technical research? Did we optimize for permissionless deployment but ignore permissionless adoption?
For other L2 teams: Is there a path to competing with Base’s distribution advantage, or should the focus shift to becoming specialized chains for specific use cases rather than general-purpose competitors?
For the broader ecosystem: Does chain abstraction or shared sequencing change this dynamic, or do we just end up with Base controlling the sequencing layer too?
For all of us: If we accept that distribution beats technology in infrastructure markets, what does that mean for crypto’s decentralization goals?
I don’t have answers. Just uncomfortable questions from an engineer who spent years believing that building better tech would be enough.
What do you think—did we scale Ethereum, or did we just prove that even with permissionless tech, centralized distribution wins every time?
