Arbitrum, Optimism, and Base respond to Vitalik Buterin’s views on layer 2 scaling

Vitalik Buterin criticized the existing L2 scaling model, asserting its security is inadequate and urged a move towards specialization. His insights initiated a response from L2 builders who agreed the approaches must evolve beyond being cheaper alternatives, aiming for more defined roles.

As the discourse continues, Steven Goldfeder from Arbitrum reinforced that L2s remain crucial for scalability, while Jesse Pollak of Base focused on user onboarding and differentiating through features. Meanwhile, Eli Ben-Sasson from StarkWare highlighted that ZK-native L2s align with Buterin’s specialization vision.
