[USDT0 Announces Security Architecture Details: Implements 3/3 Validation Mechanism and Launches $6 Million Bug Bounty Program] Reported by Jinse Finance, on May 9, following the Kelp security incident, Tether's asset interoperability protocol USDT0 disclosed details of its security architecture. It stated that the current system utilizes a proprietary DVN (Decentralized Validation Network) with message veto rights, requiring three independent validators to achieve 3/3 consensus based on different codebases before cross-chain messages can be settled. The current validation nodes include USDT0's proprietary DVN, LayerZero, and Canary, with plans to expand to 4/4 and 5/5 validation mechanisms in the future. USDT0 also mentioned that all multi-signature transactions must undergo multiple reviews by internal teams, external security teams, and auditing institutions before signing. Relevant contracts have been audited by institutions such as Guardian and OpenZeppelin, and a $6 million bug bounty program has been launched on Immunefi.
