AI agents cut resources to break ECDSA signatures by 90%, beating Google's estimate
IgorCarron · x · 2026-11-11
Eli Ben-Sasson highlights the underreported ECDSA/fail challenge: participants used AI agents to reduce the resource cost of the Shor's algorithm operation needed to break quantum-vulnerable ECDSA signatures (used by Bitcoin, Ethereum and more) by over 90% — in just a few months, and 70% better than Google's own estimate.
Igor Carron shares it with a terse "And they fall...". The takeaway: AI is accelerating the efficiency of quantum attacks and could bring Q-Day closer, a warning for ECDSA-dependent systems.
