This means that as long as funds have never been transferred from a p2pkh address, the public key is not known and the private key cannot be derived using a quantum computer.
Some address types are already quantum-resistant. Of course the addresses that are just public keys (not hashed public keys) are vulnerable.

- jcuenod 6y agoThanks; this looks on point.
- cozzyd 6y agoThat's half of what that article (which is excellent!) says. Presumably those unused addresses are lost and would lead to some devaluation but not that much. The harder to understand half is that if a quantum computer can break the public key before the transaction is verified (which takes some time, by design) then that's also game over, although it's not clear if that's possible or not.
