[Nic Carter: 'Quantum Canary' Cannot Provide Adequate Warning, Bitcoin Must Immediately Begin Preparing for Post-Quantum Migration] Castle Island Ventures partner Nic Carter published a long post on the X platform, pointing out that the 'quantum computing canary warning' mechanism cannot provide BTC with sufficient buffer time. Currently, classical computers are capable of solving elliptic curve discrete logarithm problems (ECDLP) of approximately 117 to 130 bits. However, results from quantum computing below this threshold are often questioned for potential 'classical cheating' or pre-set answers, making it impossible to form an effective signal. Nic Carter believes that once quantum computers truly surpass this classical limit, they may only be months away from directly attacking Bitcoin's 256-bit secp256k1 curve. Meanwhile, Bitcoin's migration to post-quantum signatures could take several years to complete.
