After losing almost 60% of its value, ZEC—the native token of the privacy-focused network Zcash—is showing signs of recovery. Over the past few days the coin has climbed back above $400, retracing losses from the $300 range as confidence begins to return.
The price rebound coincides with the Zcash team announcing an upgrade that addresses an integrity flaw in the network. The Ironwood Upgrade, planned for late July, will enable independent verification of the circulating ZEC supply and prevent the creation of counterfeit coins.
Zcash’s Ironwood Upgrade Scheduled for July
The Ironwood upgrade became necessary following a series of events that began when Zcash researcher Taylor Hornby disclosed a vulnerability affecting the network’s most recent shielded pool, Orchard. Hornby identified a potential counterfeiting flaw in Orchard, prompting the development team to deploy a two-stage fix that was applied by June 2.
In the ensuing debate within the crypto community, developers acknowledged that it was impossible to determine whether the vulnerability had been exploited before the patch. They said bad actors could potentially have minted counterfeit ZEC, increasing the circulating supply, but there was no mechanism to audit and confirm the supply at that time. That gap is what Ironwood aims to close.
When activated in late July, Ironwood will implement a turnstile mechanism designed to protect users from any hypothetical counterfeit coins. The upgrade will transition ZEC activity from the Orchard pool to a new Ironwood pool, allowing node operators to audit the total supply independently—removing the need to rely solely on developer assurances.
Although Ironwood uses the same underlying Orchard protocol, it will start with a fresh pool. Wallets will stop sending and receiving transactions on the old Orchard pool; instead, transactions will be routed through the new Ironwood pool. These changes are intended to be seamless for end users.
ZEC Recovers, Rallies Above $470
One of the most important effects of the Ironwood upgrade is the added confidence it should bring to the Zcash community by providing a verifiable supply audit. That assurance could reduce the risk of large sell-offs that drove the token sharply lower last weekend.
Shortly after news of the Orchard vulnerability became public, BitMEX co-founder Arthur Hayes reportedly sold his entire ZEC position. His exit amplified selling pressure, helping push the price down from around $578 to near $255 as fear and uncertainty spread.
With developers deploying fixes and planning Ironwood to enhance supply integrity, ZEC has rebounded strongly. Over the past week the token has gained more than 56%, and at the time of writing it was trading above $470 according to CoinMarketCap data.
