Quantum computing
A large enough quantum computer would break the signatures that protect every coin whose public key is visible on the chain. The list has discussed it since 2011; since 2024 the threads are about concrete post-quantum proposals, BIP 360 among them, and about what to do with coins that nobody can move.
71 threads and 710 messages, 2 Mar 2012 to 24 Sep 2026.
