optimism

📅 February 18 - United States | The Layer 2 ecosystem is undergoing a significant shift: Base, the network incubated by Coinbase and the largest chain within the OP Stack Superchain, announced that it will cease relying on Optimism and migrate to a “unified solution” operated by the Base team itself.

📖The transition will not abolish transparency: the protocol will remain public and openly specified, and third parties are encouraged to implement alternative clients compatible with the specifications.
In the short term, Base will maintain compatibility with the OP Stack specification, but there will be concrete operational changes: node operators will need to migrate to a new Base client to continue participating in future hard forks.
The ecosystem's security is also being adjusted: Base replaces Optimism on its security council and adds an additional "independent signatory".
The technical roadmap already announces a Base V1 hard fork that will introduce Fusaka support and replace optimistic tests with Base-specific tests based on TEE/ZK proofs; In addition, there are at least two more hard forks planned to further reduce dependence on Optimism, with Base V3 scheduled around Ethereum's next Glamsterdam upgrade.
In short, it's a gradual but determined transition to a stack optimized for Base's specific needs: lower complexity, greater maintenance control, and direct adaptation to use cases like sequencing and low latency.

Topic Opinion:
I see this decision by Base as a logical step towards the professionalization of Layer 2: reducing external dependencies and optimizing the stack for real-world production use cases makes both technical and commercial sense.
💬 Do you think Base will gain more speed and control by moving away from the OP Stack?
