- Developers patched the Orchard pool flaw within days through coordinated emergency network upgrades.
- The Ironwood plan would create a new privacy pool and block new coin creation in the old Orchard pool.
- Node operators would be able to verify the total ZEC supply without relying on developer assurances.
- ZEC traded near $437 on Monday but remained down roughly 22% over the past week.
Zcash recovered about 45% from last week’s low near $300 after developers introduced a plan to address a disclosed flaw. The token traded around $437 on Monday, yet it still showed a weekly decline of nearly 22%. The rebound followed emergency fixes and a formal proposal called Ironwood that aims to confirm the integrity of the coin supply.
Zcash Rebounds After Emergency Patch and Proposal
ZEC fell sharply after Shielded Labs disclosed a counterfeiting bug in the Orchard privacy pool. The flaw has existed since 2022 and could have enabled unlimited fake ZEC creation without detection. Developers moved quickly and released emergency upgrades within days to close the vulnerability.
Shielded Labs worked with the Zcash Foundation and the Zcash Open Development Lab on the fix. They coordinated the rollout with mining pools ViaBTC and Foundry to secure network support. On June 6, the groups proposed that Ironwood strengthen verification of the total supply.
Ironwood would create a new privacy pool that uses repaired code and blocks new coin creation in Orchard. Once activated, node operators could total balances across pools and confirm the correct ZEC supply. Users would not need to rely on statements from developers or wait for funds to migrate.
The plan could also expose any prior abuse of the flaw. As coins leave the old pool, counterfeit tokens would surface or remain stranded and destroyed. Shielded Labs said it believes exploitation was unlikely based on current reviews.
Investor Chamath Palihapitiya addressed the proposal in his newsletter. He wrote that Ironwood would let anyone running a node “verify the supply is clean.” Developers have not set a firm activation date and said testing and coordination could extend timelines.
Network Upgrade Aims to Secure ZEC Supply Integrity
The Orchard pool hides transaction details through opt-in privacy features. The disclosed bug threatened that design by allowing potential counterfeit issuance inside the shielded environment. After disclosure, the token price dropped quickly and erased recent gains.
ZEC reached about $300 on Friday before rebounding to near $437 by Monday. The recovery reflected market response to the patch and upgrade plan. Despite the bounce, the token remained down roughly 22% over seven days.
The Ironwood framework would prevent new activity in the compromised Orchard pool. It would also introduce a separate pool that runs only the corrected code. This structure would allow transparent confirmation of the total circulating supply across pools.
Developers stated that anyone running Zcash software could audit balances independently. They emphasized that the system would not require trust in centralized verification. The teams continue to build and test the upgrade before setting an activation schedule.
