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

Ledger CTO believes that Bitcoin will be the least of our problems if asymmetric cryptography falls. Ledger CTO Charles Guillemet has rebuffed fears that AI could break Bitcoin’s cryptography in the coming months. He said there is no sign of an imminent breakthrough that could break the Elliptic Curve Digital Signature Algorithm (ECDSA), the cryptographic system used to secure Bitcoin transactions. Is Fear Overblown? Guillemet went on to explain that if asymmetric cryptography were broken, “Bitcoin will be the least of our problems.” Internet security, banking systems, secure communications, and critical infrastructure could all face serious problems. While he admitted that recent mathematical advances are impressive, the exec said they do not represent a practical breakthrough against ECDSA. “And if your logic is that nothing can be trusted until it’s proven unbreakable, congratulations. By that standard, nothing is safe, including hashes.” Guillemet urged people to follow cryptography research and take potential risks seriously. But he warned against treating theoretical progress as a sign that a cryptographic crisis is just months away. The comments come after Ethereum Foundatio...
