The Arbitrum next-generation off-chain dispute resolution protocol BOLD testnet is now live

ChainCatcher news, Arbitrum developer Offchain Labs announced the official launch of its next-generation off-chain dispute resolution protocol Arbitrum BOLD testnet. BOLD aims to provide interactive fraud proofs in operation for optimistic rollup networks, marking a key step for Arbitrum towards fully permissionless verification and a higher degree of decentralization.

It is reported that the BOLD protocol ensures the correctness of Arbitrum's state on Ethereum by allowing anyone to verify or challenge transactions brought back from Arbitrum to the Ethereum mainnet. It is now deployed on a public testnet, where validators can experience the operation of this cutting-edge protocol by submitting assertions to the Sepolia testnet. Offchain Labs is expected to propose activating BOLD on Arbitrum Sepolia soon, with voting conducted via Tally.
