Offchain Labs is thrilled to announce a groundbreaking milestone: the launch of the Arbitrum Bold testnet is now live. Powered by fraud-proof rollup systems, Arbitrum Bold is poised to revolutionize dispute resolution mechanisms for years to come. This achievement further validates the robustness of the Arbitrum blockchain, equipped with fraud-resistant features.

The innovative team at Arbitrum is passionate about developing a secure dispute resolution ecosystem. With a focus on efficiency, scalability, and safety, the technical experts at Offchain Labs have rigorously tested BOLD to ensure its resilience.

BOLD-enabled public testnets validate claims on Ethereum Sepolia, Ethereum's testnet, offering a cutting-edge dispute resolution process. Plans are underway to activate BOLD on Arbitrum Sepolia pending a proposal.

Permissionless validation is crucial for decentralization and Arbitrum's ecosystem. BOLD eliminates the need for a permission validator role, enhancing network security and flexibility. This democratization of validation contributes to decentralization and adaptability.

Tailored for the Arbitrum community, BOLD offers permissionless validation, enhanced security, pooled funding for collective challenges, and robust mathematical foundations. These features ensure participants can manage their own validator nodes and contribute to the consensus process.

In addition to network security, BOLD verifies Ethereum withdrawals, leveraging Offchain Labs' expertise in interactive protocol configuration.

Pooled funding functionality in BOLD safeguards Arbitrum against invalid claims and facilitates their resolution.

Following rigorous development procedures and formal safety assurances, BOLD undergoes a thorough audit examination by Trail of Bits, highlighting the commitment to decentralization and security enhancements.

The introduction of BOLD marks a critical step towards mainnet readiness, with significant potential for the future. A question-and-answer session featuring key team members will be held on April 18, 2024.

Undoubtedly, BOLD is pivotal in advancing permissionless verification and decentralization on Arbitrum. Offchain Labs will initiate a voting process for the activation of BOLD on Arbitrum Sepolia.
