Arbitrum Launches BOLD Testnet for Next-Generation Fraud Proof Protocol

According to BlockBeats, on April 16, 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 at work for optimistic rollup networks, and is a key step for Arbitrum to move towards fully permissionless verification and a higher degree of decentralization. The BOLD protocol ensures the correctness of Arbitrum's state on Ethereum by allowing anyone to verify or challenge transactions withdrawn from Arbitrum to the Ethereum mainnet. It is now deployed on the public testnet, and validators can experience the operation of this cutting-edge protocol by submitting assertions to the Sepolia testnet. It is expected that Offchain Labs will initiate a proposal to activate BOLD on Arbitrum Sepolia and vote through Tally soon.
