AI, ECDSA, and Bitcoin’s Endgame? Ledger CTO Pushes Back Against Cryptographic Apocalypse Predictions

Ledger CTO Charles Guillemet pushed back on claims that AI poses an imminent threat to Bitcoin’s ECDSA cryptography, arguing that AI does not by itself make deriving private keys from public keys practical. The main risk would come from sufficiently powerful quantum computers, which could break the relevant cryptography—not from today’s AI systems. Bitcoin’s security is therefore not facing an immediate AI-driven endgame, though advances in computing keep long-term cryptographic migration on the agenda.
