Bitcoin currently verifies digital transaction signatures using the classical cryptographic algorithms ECDSA and Schnorr, which existing non-quantum computers are unable to reverse-engineer

Coinbase recommended that post-quantum Bitcoin software evaluations prioritize implementations that avoid timing leaks, run reliably across platforms, and remain secure if random-number generators fail
