Arbitrum DAO has opened a vote on upgrades to the Arbitrum One and Nova L2 networks that would activate the BoLD dispute-resolution protocol.
LIVE: Proposal to activate Arbitrum BoLD is up for a final vote.
BoLD is a new dispute resolution protocol enabling permissionless validation.
If approved, anyone can participate in validation and defend against malicious claims to an Arbitrum chain’s state.…

The AIP also proposes adding ConsenSys’s infrastructure project Infura to Nova’s validator whitelist.
Integrating BoLD is intended to improve security by imposing a fixed window for resolving disputes over Arbitrum’s state. This protects against delay attacks that can disrupt the network.
The protocol removes the need for a permissioned validator set and ensures any “honest party” can prevail over attackers.
Currently, Arbitrum chains rely on a permissioned set of validators to prevent delay attacks.
With BoLD enforcing a fixed time limit on dispute resolution, delay risks are mitigated, making permissionless validation possible. pic.twitter.com/8AsWUC9xS7

Developers added that activating BoLD would also strengthen censorship resistance for L3 networks built on the Orbit stack.
Voting ends on January 24. At the time of writing, 100% of participating voters back the AIP.
In April, Offchain Labs, the firm behind Arbitrum, развернула BoLD on a testnet.
