Symmetric encryption and hash functions with 256 bits are already quantum proof.
Post-quantum algorithms are here in few years. Some of them are already in use in critical applications.
- t_mann 4y agoImportantly, Bitcoin and Ethereum are (inadvertently) almost quantum-proof (because the addresses are hashes of the public keys), just not quite (because the public keys still get exposed during transactions). But at least the latter should be fixable (because the community is quite used to changes to the protocol anyway).
