Zcash Recovers as Network Prepares for Integrity-Boosting Upgrade
Zcash (ZEC), the native cryptocurrency of the privacy-focused Zcash network, is showing signs of recovery after a significant price drop. The digital asset has surged back above $400 in recent days, rebounding from a low in the $300 range.
This price resurgence coincides with the Zcash team’s announcement of a forthcoming upgrade designed to address a critical integrity flaw within the network. The Ironwood Upgrade, slated for late July, aims to empower users with the ability to independently verify the circulating supply of ZEC, thereby preventing the creation of counterfeit coins.
The necessity for the Ironwood upgrade emerged following a series of events initiated by Zcash researcher Taylor Hornby. Hornby identified a vulnerability within the network’s most recent shielded transaction system, known as Orchard. This counterfeiting vulnerability in Orchard prompted the Zcash team to implement a two-stage upgrade, which was completed by June 2.
Amidst considerable concern from the cryptocurrency community, developers acknowledged that it was impossible to definitively determine whether the vulnerability had been exploited by malicious actors prior to the fix. They indicated that it was plausible that bad actors could have minted fraudulent ZEC coins using the bug, thereby inflating the circulating supply. However, without a method to audit the total ZEC supply, confirming the absence of such counterfeiting was not possible. This uncertainty underscored the need for the Ironwood upgrade.
Upon its activation in late July, the Ironwood upgrade will introduce a “turnstile” mechanism intended to safeguard Zcash users against the potential threat of counterfeit coins. This upgrade will also signify the migration of ZEC from the existing Orchard pool to the new Ironwood pool. This transition will enable node operators to audit the total supply without relying on the developers.
Crucially, the Ironwood pool will utilize the same Orchard protocol but will commence with a clean slate. Users will no longer be able to send or receive payments on the old Orchard pool; all funds will be redirected to the new Ironwood pool. These operational changes are designed to be seamless for end-users.
A significant benefit of the Ironwood upgrade is its potential to reassure the Zcash community that no counterfeiting occurred before the Orchard bug was rectified. This assurance is expected to mitigate further sell-offs that could lead to substantial price declines, similar to the drop witnessed recently.
The news of the Zcash bug had a swift impact, with BitMEX co-founder Arthur Hayes reportedly selling his entire ZEC holdings shortly after the vulnerability became public. Hayes’ divestment intensified selling pressure on the asset, fueled by widespread fear, uncertainty, and doubt, which sent the coin plummeting from approximately $578 to near $255.
As developers continue their work to resolve the underlying issue, ZEC has experienced a notable rebound, gaining over 56% this week. At the time of reporting, the asset was trading above $470, according to data from CoinMarketCap.
