Build on Bitcoin upgrades to ZK fraud proofs, aiming to climb L2Beat’s decentralization rankings and unlock Ethereum-level DeFi on Bitcoin.
Layer-2 blockchain network Build on Bitcoin (BOB) has rolled out a major technical upgrade that brings it closer to getting a fully decentralized mark on L2Beat, a platform that ranks the maturity and decentralization of layer-2 networks.
BOB, which aims to bring Ethereum-style decentralized finance (DeFi) capabilities to Bitcoin, has implemented zero-knowledge (ZK) fraud proofs within an optimistic rollup framework.
This means that BOB is using an optimistic rollup structure but replaces the traditional and slow fraud-checking process with faster ZK fraud proofs — a shift that allows transaction disputes to be resolved in minutes using cryptographic proofs.
