Key Takeaways:
Base, the Coinbase-incubated Ethereum Layer 2 network holding around $12 billion in total value locked, will overhaul its security model to adopt zero-knowledge proofs for chain finality. The upgrade, announced May 4, represents a major architectural shift for one of the largest L2 ecosystems.
"Expanding Base with ZK proofs is a meaningful step to deepen the network’s security and resiliency," Wilson Cussak, Head of Base Chain, said in a statement. "As the network has grown, so has the need to keep strengthening the infrastructure that users and developers rely on every day."
The network will integrate the SP1 zero-knowledge virtual machine (zkVM) from Succinct Labs to generate proofs, replacing the multi-day challenge window tied to its current optimistic rollup design. This change introduces cryptographic finality, cutting the path to one-day settlement for withdrawals and providing a trust-minimized mechanism for moving capital back to Ethereum's mainnet.
The pivot makes Base the largest single Ethereum operator to use ZK proofs for finality and aligns the network with Ethereum co-founder Vitalik Buterin's long-term vision. Buterin has described ZK-EVMs as Ethereum's block validation "endgame," expecting them to become the dominant proving method between 2027 and 2030. The upgrade comes as Base continues to attract significant projects, including the recent migration of privacy-focused blockchain Horizen ($ZEN) to the L2 network in Q1 2026.
