A new, unified stack for Base Chain

Base is moving its foundational software to a unified, Base-operated stack called base/base, after which node operators will need to follow releases from that repository instead of Optimism's. The company says the change aims to speed up innovation, scaling and security, with a target of six smaller hard forks per year, double the current three. Base states it remains a Stage 1 Decentralized Rollup and is adding an independent signer to the Base Security Council in place of Optimism. Node operators must migrate to the Base client in the coming months to stay compatible with future hard forks, while all RPCs, including those in the optimism namespace, will remain supported.
