9-Minute Attack Window, 7.1 Million BTC Exposed: How Bitcoin Can Save Itself Under Quantum Threats
The report believes that the progress in quantum computing is real but only incremental, and there are currently no quantum computers related to cryptography. The exposure of Bitcoin is limited to ECDSA: address reuse and static attacks on P2PK, as well as in-transit attacks with a window of about 10 minutes in the memory pool. Approximately 7.1 million BTC public keys have been exposed, of which about three-quarters are on reused addresses, which can reduce risk through migration; about 1.8 million are considered lost. Current work includes stopping address reuse, advancing SHRINCS post-quantum signatures, and reaching a consensus on the disposal of P2PK coins.
