Ethereum’s Layer-2 scaling solution, Arbitrum, has proposed a new dispute resolution protocol called BoLD (Bounded Liquidity Delay) to strengthen its ecosystem.
The Arbitrum team announced this proposal on January 6.
Arbitrum’s BoLD Proposal Received 99.79% Community Support
Currently, Arbitrum DAO has opened the final on-chain vote for the BoLD proposal. At the time of writing, propose has received absolute support from the Arbitrum community, with 99.79% of votes in favor.
However, less than 1 million people voted out of a total of 201.5 million. Voting will end on January 24.
The BoLD protocol aims to facilitate permissionless validation and protect against delay attacks.
“While current Arbitrum chains benefit from effective cheating proofs, BoLD introduces a number of subtle yet innovative changes that allow anyone to challenge and win disputes – all within a fixed time period,” Arbitrum said.
Furthermore, validation on Arbitrum One and Arbitrum Nova is currently limited to a small group of validators. Arbitrum DAO implemented this measure to prevent “latency attacks.
These attacks occur when malicious parties take advantage of the challenge period to repeatedly raise disputes to delay the confirmation of claims.
According to the proposal, BoLD will address this issue by resolving disputes within a fixed time frame. Currently, this is equivalent to one challenge period, approximately 6.4 days.
The protocol ensures that the maximum total time to resolve a dispute will not exceed two challenge periods: one to raise the dispute and one to resolve them.
Additionally, the BoLD includes a two-day period for the Security Council to intervene if necessary. This permissionless validation system is an important step towards Arbitrum’s goal of achieving Stage 2 Rollup status.
With BoLD, any honest party can assert and mount its assets to make accurate Layer-2 state statements and challenge malicious actors. This will lead to a more open and secure ecosystem for Arbitrum.
Currently, the protocol is being deployed on the public testnet in an alpha release. It allows developers and users to test and explore BoLD features. The team hopes that the BoLD proposal will help Arbitrum maintain its leadership role in Ethereum rollups.
