Core Viewpoint - Base, the largest chain in the OP Stack Superchain, is transitioning to an independent codebase, moving away from Optimism's technology, which has significant implications for its economic future and operational control [2][6]. Group 1: Company Developments - Base announced it will consolidate its sequencer, proofs, and core infrastructure into a single Base-managed repository, moving away from reliance on Optimism's tech stack [2][3]. - The new stack will replace Optimism's optimistic proofs with Base-specific TEE/ZK proofs, and Optimism will be removed from the Base Security Council [3]. - Base has historically generated over 90% of the Superchain's total revenue, indicating its critical role in the ecosystem [6]. Group 2: User Impact - There will be no disruption for end users during this transition, although node operators will need to migrate to the new base/base releases [4]. - The mission of Base remains focused on creating a secure, low-cost, developer-friendly environment for building on-chain applications [5]. Group 3: Market Position - Base currently holds a total value locked (TVL) of $3.85 billion and is the dominant Layer 2 by activity, which positions it favorably for future growth and control over its economic destiny [8].
