L2 projects push back on Vitalik Buterin's call for redefinition

Major Layer 2 projects are pushing back against comments from Ethereum (ETH) founder Vitalik Buterin suggesting a redefinition of their role in the ecosystem, Cointelegraph reported. Buterin had argued that many L2s depend on security-vulnerable multi-signature bridges while the Ethereum mainnet is simultaneously boosting its own processing capabilities. He asserted that L2s must provide unique value beyond simply serving as a scaling solution. - Karl Floersch, founder of Optimism (OP): While building L2 stacks is welcome, there are practical obstacles such as a lack of tools for cross-chain applications. - Steven Goldfeder, founder of Offchain Labs, the developer of Arbitrum (ARB): The core value of L2s is scalability, and it would be difficult for the ETH mainnet to replace the traffic they handle. - Jesse Pollak, core developer at Base: L2s should not simply be cheaper versions of ETH and must introduce differentiated features like account abstraction.
