Base moves beyond OP Stack as it rebuilds its core stack

Base, Coinbase’s Ethereum layer-2 network, announced it is moving away from the Optimism Stack to develop its own unified Base stack infrastructure. This strategic shift aims to streamline development, decrease dependence on external codebases, and enable more frequent upgrades, targeting up to six hard forks annually, compared to about three previously. Base, which launched in August 2023 using Optimism's framework, has become a major scaling solution. While users require no immediate action, node operators must migrate to the Base client before future hard forks, though current RPCs will remain supported. Future roadmap plans include transitioning from optimistic proofs to TEE and ZK proofs, aligning with Ethereum L1 upgrades, and introducing new transaction types and fee model refinements.
