Zcash Founder Warns Orchard Bug Could Have Created Undetectable Counterfeit ZEC
A critical security vulnerability in Zcash's Orchard privacy circuit was discovered on May 29, 2026, that could have enabled unlimited counterfeit ZEC generation without cryptographic detection. The flaw, found using AI analysis, allowed false elliptic curve multiplication inputs to pass verification, and due to Orchard's privacy design, there is no way to determine if the bug was exploited before patching.
