Wu says that, according to the Base engineering team blog, Base will integrate the key components running the network into a proprietary unified codebase, and node operators will need to follow Base's release versions rather than directly following Optimism's versions. The official said this move will increase the upgrade frequency from three times a year to six times, and in subsequent hard forks, promote the upgrade from optimistic proofs to TEE/ZK proofs, while maintaining Stage 1 Rollup status and adding independent signers to the Base Security Committee.
