  "account": "On August 6th, 2026, the blockchain platform Sui announced the adoption of two post-quantum signature schemes to enhance quantum readiness. The company explained that conventional public keys are exposed permanently upon account transactions, making them vulnerable to quantum attacks like Shor's algorithm. To mitigate this risk, Sui is employing ML-DSA-65 for everyday transactions and SLH-DSA-SHA2-128s for smart contract vaults. Both signature schemes follow NIST's standardized post-quantum algorithms and are designed to coexist without undermining each other. Sui's cryptographic agility allows for seamless integration of new algorithms without disrupting the network's fundamentals. The company emphasizes that users retain their recovery phrase and address while transitioning to the new security measures. The rollout timeline includes native ML-DSA-65 accounts reaching Testnet by year-end and Mainnet authentication by Q1 2027. Independent audits are ongoing, and further optimization is planned to address the increased transaction size resulting from post-quantum signatures.",
