Arbitrum, Optimism and Base weigh in after Vitalik questions L2 scaling model
Base’s Jesse Pollak says L2s can’t be “Ethereum but cheaper” as builders respond to Vitalik Buterin’s call for specialization.
Several layer-2 builders responded after Ethereum co-founder Vitalik Buterin said the original vision of L2s as the primary scaling engine “no longer makes sense,” calling for a shift toward specialization.
In a Wednesday post, Buterin argued that many L2s have failed to fully inherit Ethereum’s security due to continued reliance on multisig bridges, while the base layer is increasingly capable of handling more throughput via gas-limit increases and future native rollups.
The comments prompted responses from Ethereum layer 2s, who broadly agreed that rollups must evolve beyond being cheaper versions of Ethereum but diverged on whether scaling should remain central to their role.
