New Bitcoin quantum proposal offers Satoshi Nakamoto a way to prove control without moving BTC

Venture fund Paradigm has introduced a novel design aimed at addressing potential future vulnerabilities to Bitcoin's cryptographic security from quantum computing. This proposal would enable Bitcoin holders, including figures like Satoshi Nakamoto, to privately timestamp proof that they control specific keys, particularly those associated with older addresses that might become susceptible to quantum attacks. The objective is to establish a 'rescue path,' allowing proof of ownership without needing to move BTC, should the Bitcoin protocol eventually require the sunsetting or migration of these legacy addresses due to advancements in quantum technology. This initiative seeks to preemptively safeguard against future quantum threats to Bitcoin's long-term security and address control.
