According to BlockBeats, Offchain Labs, the developer of Arbitrum, announced the official launch of its next-generation off-chain dispute resolution protocol, Arbitrum BOLD testnet, on April 16. The BOLD protocol is a crucial step towards complete permissionless verification and a higher degree of decentralization for Arbitrum. It aims to provide interactive fraud proofs for optimistic rollup networks.

The BOLD protocol ensures the correctness of Arbitrum's status on Ethereum by allowing anyone to verify or challenge transactions withdrawn from Arbitrum to the Ethereum mainnet. It has now been 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 soon initiate a proposal to activate BOLD on Arbitrum Sepolia and conduct voting through Tally.
