Summary
Zcash founder Zooko Wilcox said a security audit by Anthropic's Claude Mythos artificial intelligence model found no serious vulnerabilities in the privacy-preserving cryptocurrency's protocol. Requested by Shielded Labs, a Swiss-based non-profit supporting the development of Zcash, the AI security audit did not find “any more serious bugs” in the Zcash protocol, according to a Saturday X post by Wilcox. On June 3, Zcash developers temporarily suspended Orchard transactions after discovering a vulnerability in the shielded pool. The issue stemmed from a four-year-old forgery bug in the Orchard shielded pool that was discovered by security researcher Taylor Hornby with the help of Anthropic's Claude Opus 4.8 model.
