Base Ditches Optimism Infrastructure for Independent Tech Stack

Base, the Ethereum Layer 2 network backed by Coinbase, has made a significant move to reduce its reliance on Optimism's infrastructure. As of Tuesday, Base announced it is consolidating its codebase away from Optimism's OP Stack into a Base-operated repository.

This change aims to increase Base's hard fork schedule from three to six per year and will require node operators to migrate from Optimism releases to Base's client software to remain compatible with future network upgrades.

Base's new unified stack, designated 'base/base,' consolidates previously distributed codebase elements into a single repository built on open-source components including Reth. The transition also includes the addition of an independent signer to replace Optimism's position in the Base Security Council.

The move reduces Base's dependency on code maintained by Optimism, Flashbots, and Paradigm, which currently operate various network components across multiple repositories. Despite this change, Base will continue purchasing support from Optimism through its OP Enterprise program.
