Arbitrum DAO Proposes BoLD Protocol for Stronger Network Security

• Arbitrum DAO votes on implementing BoLD protocol for better security and efficiency.
• BoLD will enable permissionless validation on Arbitrum One, promoting decentralization.
• Arbitrum Nova will keep permissioned validation but add Infura’s validator for reliability.

The Arbitrum DAO is moving forward with a proposal to implement the Bounded Liquidity Delay (BoLD) protocol across its network, including Arbitrum One and Arbitrum Nova.

If approved, this proposal will update the current dispute resolution system with a more effective and secure protocol. The BoLD integration is anticipated in February 2025. Currently, validators have a 6.4-day window to dispute assertions about the chain’s state.

This system, while functional, is vulnerable to delay attacks, where bad actors dispute assertions to delay their confirmation. BoLD tackles this by introducing a fixed upper time bound for dispute resolution, which stops delay attacks and ensures timely assertion confirmations.

Permissionless Validation Comes to Arbitrum One

With BoLD comes a major change: permissionless validation on Arbitrum One. Now, anyone can secure the network by validating transactions a…
