Guy beats one of the best published quantum circuits for breaking ECDSA with AI

A person claims to have used AI to beat one of the best published quantum circuits for breaking ECDSA, a cryptographic algorithm used in Bitcoin and other systems.

Background

- ECDSA (Elliptic Curve Digital Signature Algorithm) is a cryptographic system widely used to secure Bitcoin, Ethereum, and many other blockchains. Breaking it would let an attacker forge signatures and steal funds. - The "best published quantum circuits" are the most efficient known algorithms that a future quantum computer could run to break ECDSA — previously considered a distant threat. - This tweet claims someone used AI to design a new quantum circuit that outperforms those known human-designed circuits, potentially bringing quantum attacks on crypto closer to reality. - The account @bbuddha_xyz posts about AI-meets-crypto research; the claim is unverified and from a single tweet, not a peer-reviewed paper.
