Arbitrum BOLD Testnet Launched by Offchain Labs

Offchain Labs, the company behind the development of the Arbitrum ecosystem, has announced the launch of Arbitrum BOLD on testnet. This new feature, known as the Bounded Liquidity Delay (BOLD), serves as a dispute protocol with interactive fraud proofs specifically designed for optimistic rollups within the Arbitrum network. Here are the key highlights of Arbitrum BOLD:

BOLD Overview

Dispute protocol with interactive fraud proofs for optimistic rollups
Allows users to run a validator node and participate in the network’s consensus process
Defends against delay attacks by bad actors disrupting data flow

According to Offchain Labs, “BOLD ensures a fixed upper-bound on the confirmation of Arbitrum states on Ethereum, empowering a single party to defend claims against multiple adversaries without engaging in individual confrontations with each of them.”

Reasoning Behind the Development of BOLD

Offchain Labs explained the rationale behind introducing BOLD, emphasizing the following points:

Validation Challenges

Current validation processes on Arbitrum One and Nova are permissioned due to vulnerability to denial-of-service attacks
Malicious validators can disrupt the confirmation of assertions, leading to delays in fund withdrawals from L2 to L1

The company’s new protocol, BOLD, offers a novel validation approach that imposes a fixed 7-day delay on confirmations without succumbing to delay attacks, thereby enabling permissionless validation on Arbitrum chains. This advancement significantly enhances the decentralization of the network.

Hot Take: The Future of Arbitrum with BOLD

Offchain Labs’ introduction of Arbitrum BOLD on testnet marks a significant milestone in the evolution of the Arbitrum ecosystem. With enhanced security measures and permissionless validation capabilities, BOLD is poised to revolutionize the way users interact with the network. Stay tuned for further updates on the progress of Arbitrum BOLD and its impact on decentralized finance (DeFi) applications.
