Ethereum L2 teams push back as Vitalik Buterin questions rollups' scaling-first mission

Ethereum co-founder Vitalik Buterin argued on Wednesday that layer-2 networks should not remain focused solely on scaling, noting security gaps and upgrades on the main chain. Leaders from Arbitrum, Base and StarkWare responded with differing views, with Arbitrum defending scaling as central while Base and StarkWare highlighted their moves toward more specialized roles. The debate underscores shifting expectations for L2 rollups as Ethereum's base layer gains higher gas limits and potential native rollup support.
