A critical vulnerability was discovered in Zcash’s Orchard pool that, in theory, could have enabled the undetected creation of fake $ZEC . Based on currently available information, the bug had reportedly existed since 2022 and was only patched in June 2026.
What makes this especially serious is not just the vulnerability itself, but the fact that, because of Zcash’s privacy architecture, it may be impossible to prove whether it was ever exploited in the past.
The market reacted immediately: ZEC sold off sharply, liquidations followed, and reports surfaced that Arthur Hayes had fully exited his ZEC position.
At the same time, the community split into two camps:
some see this as a real stress test of the network’s resilience;
others see it as a direct challenge to the idea of private issuance without a full, transparent audit.
The core issue is simple:
the market isn’t just reacting to the existence of a bug — it’s reacting to the inability to prove that the bug was never used.
And that may be far more damaging than any ordinary daily price drop.
