Arbitrum DAO Votes on BoLD Protocol to Enhance Ecosystem Security
The Arbitrum DAO is voting on the AIP proposal to implement the Bounded Liquidity Delay (BoLD) protocol across Arbitrum One and Arbitrum Nova, with a rollout planned for February 2025.
Key points about BoLD:
- Introduces interactive fraud proofs for optimistic rollups.
- Proven effective on the Arbitrum testnet since April 2024.
- Enhances network security against malicious attacks through a permissionless dispute resolution system.
- Disputes focus on deterministic L2 state execution rather than individual validators.
- Resolution period set at 13 days plus a two-day grace period.
The proposal aims to address the “State Validation” risk in L2Beat’s analysis and facilitate Arbitrum's evolution into a Stage 2 rollup. Community support is strong, with current votes indicating unanimous approval.
BoLD will be available as an upgrade for all Orbit chains, promoting wider adoption of its fraud-proofing mechanism, transitioning from a permissioned to a permissionless model.
Arbitrum stated that "BoLD will eventually replace the current, permissioned fraud-proof mechanism." The protocol is audited and tested, positioning Arbitrum for improved scalability and security.
