Arbitrum, Optimism, and Base respond to Vitalik: L2s need to move towards specialization

Foresight News reported, according to Cointelegraph, that Ethereum co-founder Vitalik Buterin tweeted that the original vision of L2 as the main scaling engine is no longer applicable, and called for a shift towards specialization.

Optimism co-founder Karl Floersch responded by welcoming the construction of modular L2 stacks, but pointed out that Stage 2 is not yet ready, withdrawal windows are long, and cross-chain tools are insufficient, expressing support for native rollup precompiled contracts. Arbitrum co-founder Steven Goldfeder emphasized that scaling remains the core value of L2, noting that during periods of high activity, Arbitrum and Base process over 1000 TPS, far exceeding Ethereum, and warned that if Ethereum becomes unfriendly to rollups, institutions may turn to independent L1s.

Base lead Jesse Pollak stated that L1 scaling benefits the ecosystem, and L2 should not be just a "cheaper Ethereum." Base focuses on user onboarding and applications, account abstraction, privacy, and other specializations. StarkWare CEO Eli Ben-Sasson hinted that Starknet already meets the criteria for specialization.
