The Zcash Orchard pool is back. As we reported, the network had suspended all Orchard transactions while a coordinated protocol fix was deployed across miners, node operators, and infrastructure teams. That process is now closed.
The Zcash Open Development Lab confirmed the hard fork completed at 00:10 EDT on June 3. Orchard transactions are processing normally again.
Second Patch Was Needed
Getting there required more than one attempt. The first activation ran into coordination problems. A second patch followed, pushing final completion roughly two hours past the revised 23:00 EDT target ZODL had posted earlier on June 2.
ZODL explained on X that several mining pools had requested additional time to complete deployment and quality-control checks, with teams spread across multiple time zones as a key factor.
“Several mining pools requested additional time to complete deployment and quality-control procedures, particularly given the need to coordinate teams and operators across multiple time zones.”
Both consensus nodes, zcashd and zebrad, along with SDKs and supporting infrastructure, required full ecosystem-wide deployment before Orchard could come back online.
No Exploit. Funds Safe.
Seth For Privacy stated on X during the incident that the disruption was network-wide and outside the control of any wallet operator. That network-wide block is now lifted.
“Will update when that changes.”
ZODL confirmed on X there is no evidence of any exploit at any stage of this incident. Privacy was not compromised. No user funds were affected. ZEC on exchanges remained tradable throughout.
The remediation carried out in two stages marks only the second security-driven protocol upgrade in Zcash history since the network launched in 2016. Full technical disclosure is expected to follow now that the upgrade is complete.
