Zebra is an independent, consensus-compatible Zcash full-node implementation written in Rust and developed by the Zcash Foundation. It has undergone third-party audits (NCC Group in 2023; Least Authority for the NU6 and NU6.1 upgrades) and has had several 2026 vulnerabilities disclosed and patched, including remote denial-of-service and consensus-divergence bugs. In the June 2026 Orchard circuit bug response, Zebra releases 4.5.3 and 5.0.0 delivered the temporary Orchard shutdown and the NU6.2 fix; reporting states there was no evidence of exploitation.
