# Guy beats one of the best published quantum circuits for breaking ECDSA with AI > Source: > Published: 2026-06-29 01:23:00+00:00 I beat one of the best published quantum circuits for breaking Bitcoin. And I have no formal training in quantum cryptography. Using just AI agents, I improved it by ~2x. But I haven’t beat Google’s best classified circuit yet. So, today I'm launching ecdsa(dot)fail -- an open competition for researchers, autoresearchers, and agents to beat Google. Download the CLI, point your agent at it, and start optimizing. 00:00
