A number of layer-2 builders responded after Ethereum co-founder Vitalik Buterin stated 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 attributable to 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, stated in an X publish that he welcomed the problem of constructing a modular L2 stack that helps “the total spectrum of decentralization.”
He additionally acknowledged that main hurdles exist. These embrace 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 present proofs will not be but safe sufficient to assist main bridges. He additionally supported native Ethereum precompile for rollups, an idea that Buterin lately emphasised as a solution 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 stated Arbitrum was not constructed as a “service to Ethereum,” however as a result of Ethereum gives a high-security, low-cost settlement layer that makes large-scale rollups viable.
He additionally pushed again on the concept a scaled Ethereum mainnet may change the throughput at the moment dealt with by L2 networks. Goldfeder cited durations 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 would possibly launch impartial layer-1 chains somewhat than deploy on Ethereum.

Base frames differentiation, Starknet hints alignment
Jesse Pollak, head of Base, stated in an X publish that Ethereum’s L1 scaling was “a win for your complete ecosystem.” He agreed that L2s can’t simply be “Ethereum however cheaper.”
Pollak stated Base has targeted on onboarding customers and builders whereas working towards Stage 2 decentralization, including that differentiation via 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.
