following the Kelp security incident, Tether's asset interoperability protocol USDT0 has disclosed details of its protocol security architecture. It stated that the system currently utilizes a proprietary DVN (Decentralized Verification Network) with message veto authority, and requires 3 independent validators, operating on different codebases, to reach a 3/3 consensus before cross-chain messages can be settled. The current verification nodes include the USDT0 proprietary DVN, LayerZero, and Canary, with future plans to expand to 4/4 and 5/5 verification mechanisms.USDT0 also stated that all multi-signature transactions must undergo multiple reviews by internal teams, external security teams, and auditing firms before signatures are submitted. The relevant contracts have been audited by firms such as Guardian and OpenZeppelin, and a $6 million bug bounty program has been launched on Immunefi.
BitMEX Research published an article proposing an alternative soft fork to BIP-361, suggesting that dormant bitcoins vulnerable to quantum attacks be frozen only upon confirmed existence of a quantum computer capable of stealing bitcoins. The proposal introduces a “canary fund” mechanism: a special bitcoin address whose private key is unknown but theoretically crackable by a sufficiently powerful quantum computer; users may donate BTC to this address as a bounty. If funds are spent from this address, it signals confirmed quantum threat and automatically triggers the freezing mechanism. BitMEX Research states that this proposal serves as a less contentious alternative to the more controversial BIP-361.
