Zcash Orchard Soundness Bug Analysis | BlockSec Weekly
During the week of June 1, 2026, a critical soundness vulnerability was publicly disclosed in Zcash's Orchard shielded pool circuit, caused by a missing equality constraint in the halo2 ECC scalar multiplication gadget that could have enabled undetectable counterfeiting of ZEC within the Orchard pool through double-spending. The vulnerability, which existed for over four years since Orchard's activation in May 2022, was discovered by an AI-assisted security audit and patched through an emergency network upgrade (NU6.2). This single-event report covers the technical root cause (under-constrained ZK circuit relation), the AI-assisted discovery by researcher Taylor Hornby using Anthropic's Opus 4.8 model, the emergency response timeline, and the broader implications for the ZKP ecosystem.
