TechFlow reports on January 10, according to The Block, the Arbitrum DAO has initiated voting on an Arbitrum Improvement Proposal (AIP) to upgrade both Arbitrum One and Nova chains to the Bounded Liquidity Delay (BoLD) protocol. The protocol has been running on testnet since April 2024, and if approved, it will be implemented on both mainnet chains in February 2025.
The BoLD protocol aims to enhance the security of withdrawals from Arbitrum to the Ethereum mainnet by introducing a fixed time window—approximately 13 days plus a 2-day grace period—for resolving disputes over chain state. This mechanism shifts validation rights from a whitelist-based system to a fully open model, allowing anyone to participate in securing network validation and effectively reducing the risk of malicious delay attacks.
