A Bug Hid in Zcash for 4 Years. Al Found It in a Targeted Review
The timeline of $ZEC worst-case scenario that never happened:
2022 → Orchard, Zcash's most advanced privacy pool, goes live. A flaw ships with it.
2022-2026 - Audits and years of public code. Nobody spots it.
April 2026 → Shielded Labs hires security engineer Taylor Hornby to hunt for protocol bugs before attackers do.
Spring 2026 → Working with Anthropic's Al model, he finds it: a path to mint unlimited counterfeit $ZEC.
July 28, 2026 → the Ironwood upgrade (NU6.3) seals the vulnerable pool.
October 2026 → coinholders vote $1.5M to him, as part of $8M+ in retroactive grants.
From hire to fix: about three and a half months. For a bug that sat unnoticed for four years. Zooko called the governance itself the best part: coinholders funded the people who saved the network, with no company or foundation deciding alone.
I'd add one more: Zcash showed the full cycle works. Proactive hunting, disclosure, fix, payout. Most protocols have the first two steps on paper and improvise the rest.
