Base to Build Independent Stack, Reducing Optimism Reliance
Coinbase's Layer-2 network, Base, has announced a strategic shift to a unified, Base-operated software architecture, moving away from the Optimism OP Stack. This pivot is intended to give Base more autonomy over its upgrade schedule and protocol features. The move, which consolidates the stack into a new `base/base` repository, signals evolving competition among L2s and prompted brief turbulence in the OP token market.
- A key financial motivation for the split is that Base will no longer share a portion of its sequencer revenue with the Optimism treasury, retaining that income within its own ecosystem. This decision concludes a three-year technical and economic relationship. - The OP token experienced a significant price drop of over 20% in the 24 hours following the announcement, hitting a new all-time low of around $0.14. This decline extended a longer-term downtrend, with the token down approximately 97% from its all-time high. - Base plans to double its upgrade frequency from roughly three to six hard forks per year. This is intended to accelerate innovation and more quickly implement features like zero-knowledge proofs and enhanced data availability layers. - The new architecture, consolidated into a single `base/base` repository, aims to reduce dependency on external teams like Flashbots and Paradigm, who previously managed critical components. This is designed to lessen coordination overhead and simplify the development process. - Despite the move, Base will continue to collaborate with Optimism as a client of OP Enterprise for mission-critical support during the transition. Jing Wang, CEO of OP Labs, stated that the new "Unified Base Stack" still shares 99% of its code with the OP Stack. - Node operators will be required to migrate to a new, dedicated Base client to remain compatible with future hard forks, including the upcoming Base V1. - To enhance decentralization, the Base Security Council is adding a new independent signer to replace the position previously held by Optimism. - This pivot is seen by some as a blow to Optimism's "Superchain" thesis, which envisions a network of interoperable chains built on the OP Stack. Base was the largest chain in the ecosystem, often contributing over 90% of the Superchain-generated revenue that went to the Optimism Collective.
