Base, Coinbase's Ethereum Layer 2 network, is moving away from Optimism's OP Stack infrastructure to develop its own independent codebase. This represents a significant strategic shift for one of the largest L2 networks toward greater technical autonomy.
Coinbase is abandoning Optimism's OP Stack for its Base layer-2 network, choosing to bring technical development in-house for faster shipping capabilities. This decision represents a significant setback to Optimism's vision of creating an interconnected Superchain ecosystem.
Optimism has partnered with Succinct to implement zero-knowledge validity proofs that will enable instant withdrawals from the Layer 2 network. These ZK proofs will become the canonical standard across the entire OP Stack, significantly improving user experience by eliminating withdrawal delays.
