Odaily News: Starknet announced the completion of a quantum-resistant signature transfer test. A wallet account using quantum-resistant signature mechanisms completed a real transfer on the Starknet mainnet, with transaction fees of approximately 6 US cents, and the transaction can be queried via a block explorer. This account is currently an experimental, unaudited version intended primarily for research and testing.StarkWare stated that this transfer was made possible by Starknet's account model design. Unlike most blockchains that fix the signature algorithm at the protocol layer, each Starknet account is a smart contract that can autonomously define which signature schemes it accepts. As a result, users can upgrade their wallets from traditional elliptic curve signatures to quantum-resistant signatures without a hard fork, without migrating assets, and without changing their addresses.StarkWare pointed out that most blockchains face quantum computing risks because both wallet signatures and the underlying verification systems rely on elliptic curve cryptography. Once large-scale quantum computers emerge, running Shor's algorithm could break the associated cryptographic systems. Currently, the Starknet ecosystem already supports a quantum-resistant signature scheme based on Falcon-512, which is part of the NIST post-quantum cryptography standardization framework. The relevant implementation has been advanced by ecosystem teams and organizations such as OpenZeppelin.
Odaily News: Ethereum Layer 2 network Taiko released a post-mortem of the June 21 security incident, stating that the attack resulted from an off-chain signature key leak and a verification process gap. The attacker exploited these to forge proofs and bypass the Prover whitelist, rather than breaking ZK cryptography or smart contracts. The attacker stole approximately $1.75 million from cross-chain bridges and Vaults, but over $11 million in assets were protected, and no user funds were lost. Taiko has fixed the vulnerability, restored the pre-attack state, and resumed operation on July 2; an OpenZeppelin audit confirmed the fixes with no high, medium, or low-risk vulnerabilities identified. The official statement also indicated that the Unzen upgrade, scheduled for August 6, will require ZK proofs for every block to further enhance network security.
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.
