A number of layer-2 builders responded after Ethereum co-founder Vitalik Buterin mentioned the unique imaginative and prescient of L2s as the first scaling engine “not is sensible,” calling for a shift towards specialization.
In a Wednesday publish, Buterin argued that many L2s have failed to completely inherit Ethereum’s safety because of continued reliance on multisig bridges, whereas the bottom layer is more and more able to dealing with extra throughput by way of gas-limit will increase and future native rollups.
The feedback prompted responses from Ethereum layer 2s, who broadly agreed that rollups should evolve past being cheaper variations of Ethereum however diverged on whether or not scaling ought to stay central to their function.
The Ethereum ecosystem is grappling with a shifting roadmap that goals to make the bottom layer extra succesful, whereas L2s reposition themselves as specialised environments serving distinct technical wants.
Ethereum L2 builders settle for shift, differ on scaling’s function
Karl Floersch, a co-founder of the Optimism Basis, mentioned in an X publish that he welcomed the problem of constructing a modular L2 stack that helps “the complete spectrum of decentralization.”
He additionally acknowledged that main hurdles exist. These embody lengthy withdrawal home windows, the dearth of production-ready Stage 2 proofs and inadequate tooling for cross-chain apps.
“Stage 2 isn’t production-ready,” Floersch wrote, including that current proofs usually are not but safe sufficient to help main bridges. He additionally supported native Ethereum precompile for rollups, an idea that Buterin not too long ago emphasised as a technique to make trustless verification extra accessible.
Steven Goldfeder, the co-founder of Arbitrum developer Offchain Labs, took a extra forceful stance in a prolonged X thread. He argued that whereas the rollup mannequin has developed, scaling stays a core worth of L2s.
Goldfeder mentioned Arbitrum was not constructed as a “service to Ethereum,” however as a result of Ethereum offers a high-security, low-cost settlement layer that makes large-scale rollups viable.
He additionally pushed again on the concept that a scaled Ethereum mainnet might change the throughput at the moment dealt with by L2 networks. Goldfeder cited intervals of excessive exercise when Arbitrum and Base processed over 1,000 transactions per second, whereas Ethereum dealt with fewer.
He warned that if Ethereum was perceived to be hostile to rollups, establishments may launch unbiased layer-1 chains slightly than deploy on Ethereum.

Base frames differentiation, Starknet hints alignment
Jesse Pollak, head of Base, mentioned in an X publish that Ethereum’s L1 scaling was “a win for the complete ecosystem.” He agreed that L2s can not simply be “Ethereum however cheaper.”
Pollak mentioned Base has centered on onboarding customers and builders whereas working towards Stage 2 decentralization, including that differentiation by purposes, account abstraction and privateness options align with the route Buterin outlined.
StarkWare CEO Eli Ben-Sasson, whose firm develops the non-EVM Starknet rollup, supplied a short however pointed response on X, writing: “Say Starknet with out saying Starknet.”
Ben-Sasson’s remark hinted that some ZK-native L2s see themselves as already becoming the specialised function Buterin described.
