比特币量子计划假设某些算法会被破解——AI在60小时内削弱了一个

A post-quantum signature system that survived two years of expert study has been weakened by an AI model in roughly 60 hours. The result does not compromise Bitcoin, reveal anyone’s private key or demonstrate a working quantum computer. It does expose the danger of treating any new cryptographic method as a permanent answer. Anthropic’s Claude Mythos Preview helped discover a previously unknown attack against HAWK, a digital-signature scheme designed to remain secure even when powerful quantum computers become available. The attack cuts the scheme’s effective key strength approximately in half, meaning its keys would need to become much larger to preserve the intended security level. HAWK is not deployed on Bitcoin and does not protect current wallets. …
