Zcash Discovers Critical Security Flaw in Orchard Pool
- Vulnerability Discovery: Independent security researcher Taylor Hornby identified a critical flaw in Zcash's Orchard pool on May 29, which could have allowed attackers to mint unlimited counterfeit ZEC undetected, highlighting potential risks since the network's launch in May 2022.
- Flaw Details: The issue was a soundness bug in the Orchard zero-knowledge proof circuit, meaning the network could accept transactions it should reject; Hornby successfully wrote an exploit using Anthropic's Opus 4 model and a custom AI tool.
- Emergency Response: The Zcash Foundation coordinated an emergency response with the Zcash Open Development Lab, initiating private coordination with miners and exchanges on May 31, and successfully activating a soft fork on June 2 to temporarily disable Orchard actions while preparing corrective code.
- Future Plans: The NU6.2 hard fork activated on June 3, fixing the vulnerability and re-enabling Orchard, but due to its privacy-oriented nature, it is cryptographically impossible to prove whether the flaw was exploited prior to the patch; future plans include deploying a new shielded pool to ensure the authenticity of ZEC supply.
