Coinspeaker Arbitrum DAO Votes on BoLD Protocol to Boost Security: Key Changes Ahead
The Arbitrum DAO has opened voting on a proposal that could redefine the security landscape for its ecosystem. The improvement proposal, known as AIP, seeks to implement the Bounded Liquidity Delay (BoLD) protocol across Arbitrum One and Arbitrum Nova. If approved, the transition is set to roll out in February 2025.
BoLD has already proven itself on the Arbitrum testnet, where it has been live since April 2024. This protocol introduces interactive fraud proofs for optimistic rollups, a step forward in securing Arbitrum chains. By offering a permissionless and time-bound dispute resolution system, BoLD strengthens the network’s resilience against malicious attacks.
BoLD’s Core Mechanism and Validator Role
Currently, bonded validators play a critical role in Arbitrum’s structure. They post claims about the state of Arbitrum chains to the Ethereum mainnet, challenge invalid claims, and confirm valid ones through dispute resolution. BoLD enhances this system by allowing anyone to participate in the process.
With BoLD, disputes will focus on the deterministic execution of the L2 state rather than individual validators. The time-bound resolution period, set at 13 days plus a two-day grace period, ensures disputes are handled efficiently while reducing risks from delay attacks.
The proposed changes align with Arbitrum’s broader goal of becoming a Stage 2 rollup. The move addresses the “State Validation” wedge in L2Beat’s risk analysis, marking a significant step toward creating a more robust and efficient rollup ecosystem.
Community Support and Implementation Timeline
Community support for BoLD has been overwhelmingly positive, with the ongoing on-chain vote showing unanimous approval at the time of writing. The proposal promises not just security but also a leap toward decentralization by replacing the current allow-listed validator system with a permissionless model.
The implementation of BoLD will also be available as an upgrade for all Orbit chains. This opens the door for other networks in the ecosystem to adopt the protocol and benefit from its innovative approach to fraud proofing.
“BoLD will eventually replace the current, permissioned fraud-proof mechanism that powers Arbitrum chains today,” said Arbitrum.
Audited and tested for effectiveness, BoLD represents a well-calculated move for Arbitrum. By offering a secure, efficient, and inclusive framework, it sets the stage for a new era in blockchain scalability and security.
