Zcash just dropped over 50% in 48 hours. Here is what actually happened. On May 29, security researcher Taylor Hornby found a critical bug in Zcash's Orchard zero-knowledge proof circuit while auditing for Shielded Labs. The flaw would have allowed a bad actor to mint fake ZEC inside the shielded pool with zero on-chain signature, completely undetectable. What makes this terrifying for a privacy coin? If this had been exploited before discovery, there would be no way to prove it ever happened. No on-chain trace. No evidence. This was not a typical smart contract bug. This was a foundational cryptographic failure in the very component meant to make Zcash trustworthy. The vulnerability existed from Orchard's activation in May 2022 until the emergency patch on June 1, 2026. Four years. Here is what actually happened and what did not. No exploit occurred. No funds were stolen. Zcash's turnstile accounting mechanism confirms zero unauthorized value was created during the entire bug window. The flaw existed. Nobody found it earlier. Nobody used it. That distinction matters. But markets do not wait. ZEC peaked at $624 on June 4, riding the privacy narrative that built all year. Then the disclosure hit. Price crashed 57% to $264 in 24 hours. Arthur Hayes, who had publicly championed Zcash as the new gold for privacy, exited his position. Community backlash was immediate. Current price: $359. Still down nearly 43% from the peak in four days. The situation now. The emergency Zebra upgrade deployed June 1, patch effective immediately. Shielded Labs proposed a full network upgrade to formally prove supply integrity beyond the emergency patch. The Winklevoss twins backed the math-based security fix. EU ban rumors circulated, but Zcash's policy lead confirmed ZEC is not banned under MiCA. Grayscale's spot ZEC ETF application remains active on NYSE Arca. Paradigm, a16z, and Coinbase Ventures backed ZODL, the new ECC entity, in January 2026. The hard question. Bug patch...
