A Bitcoin Security Consortium report says about 7.1 million BTC are exposed to a potential quantum threat, with risks concentrated in ECDSA signatures and a nine-minute attack window cited in the report's headline. According to PANews, quantum computing advances remain gradual, and no cryptographically relevant quantum computer exists yet. Proposed responses include migrating addresses, adopting the post-quantum signature scheme SHRINCS, and reaching consensus on P2PK tokens.
