The crypto market rallied after Zcash developers swiftly patched a critical vulnerability, causing the ZEC token price to surge 10% past $615. Security researcher Taylor Hornby discovered a severe flaw in the zero-knowledge proof circuit of **Orchard**, Zcash’s advanced privacy pool. If exploited, the bug could have allowed **double-spending** within that pool. Crucially, the Zcash Foundation confirmed there is **no evidence of exploitation**, and user privacy remained entirely intact. Fixing the circuit required an emergency, two-step network upgrade: 1. **Zebra 4.5.3 (Soft Fork):** Activated at block 3,363,426 to temporarily freeze Orchard actions and block potential exploits. 2. **Zebra 5.0.0 (NU6.2 Hard Fork):** Activated at block 3,364,600 to deploy the corrected circuit and fully restore transactions. The hard fork caused temporary market confusion. Because some block explorers delayed upgrading their nodes, the blockchain briefly appeared to be halted. However, core infrastructure remained perfectly stable. All miners, exchanges, and node operators are urged to upgrade to Zebra 5.0.0 immediately to avoid running on an outdated, split chain. Rather than panicking, investors rewarded the development team's transparency and speed with a sharp double-digit price breakout. #ZcashSurges10PctAfterCriticalBugFix
