Zcash what happened?
In early June 2026, Zcash developers urgently released an update due to a critical vulnerability in Orchard, the network’s main private pool. The vulnerability was in a zero-knowledge proof scheme and theoretically allowed the creation of fake ZEC that would appear to be genuine to the network.
How dangerous is it?
Worst-case scenario:
* It was possible to create an unlimited number of ZEC inside the private pool.
* Due to privacy concerns, it is impossible to cryptographically prove whether someone exploited this vulnerability before it was fixed.
* The bug existed from approximately May 2022 to June 2026.
It was this uncertainty that scared the market more than the bug itself.
Is there evidence of exploitation?
As of today:
* The developers claim that they have not found evidence of a hack.
* No obvious inflation of the coin supply has been detected.
* But due to the architecture of the private pool, they also cannot 100% prove that this did not happen.
Why did the market react so harshly?
Because for a privacy coin, trust in mathematics is everything.
If for Bitcoin, the entire emission can be verified, then in Zcash the problem looks like this:
“Maybe no one printed anything. Or maybe they printed it. And it is impossible to prove either way.”
This is why ZEC lost tens of percent of its value after the details of the vulnerability were revealed.
My assessment
Technically:
* The vulnerability is already closed.
* The network is working.
* New transactions are protected by the corrected code.
Investment:
* The biggest problem now is not technology, but trust.
* If there is a way to prove the integrity of the coin supply, the market may gradually calm down.
* If not, this story may hang over Zcash for years as a risk of “hidden inflation.”
