Coinbase's layer-2 chain, Base, has integrated fault proofs into its main network, marking a significant step toward decentralization. This update follows the implementation of fault proofs by Optimism, the blockchain that underpins Base's technology. The introduction of fault proofs transitions Base from 'Stage 0' with full training wheels to 'Stage 1' with limited training wheels, enhancing decentralized state validation and community involvement. Key features of the fault proofs include permissionless proposals, allowing participants to validate the chain's state without relying on a central authority, and permissionless challenges, enabling users to contest fraudulent claims within a specified period. This mechanism reinforces network security by providing economic incentives to participants who identify invalid claims. Additionally, Base plans to maintain continuous challengers to uphold this security model. These advancements illustrate Base's commitment to community-driven accountability and a more decentralized framework for validating transactions and blockchain state.
