#What Caused the Surge in Zcash?
Zcash experienced a remarkable surge of over 80 percent from its low point on Friday after the development team addressed a significant vulnerability in its Orchard shielded pool. They also proposed an upgrade aimed at restoring confidence in the privacy coin's circulating supply.
ZEC's price increased from roughly $250 on Friday to more than $450 by Monday morning, according to CoinGecko data. This rebound partially reversed a sharp selloff that was triggered by the announcement of a bug capable of allowing malicious actors to create counterfeit ZEC within Orchard.
As of now, the token is trading close to $450, boasting a market capitalization of approximately $7.4 billion and over $1 billion in trading volume within a 24-hour period.
#How Did Developers Respond?
Following the discovery of this vulnerability, Zcash developers and key players in its ecosystem acted swiftly. They implemented a network upgrade on June 2, which successfully patched the issue. Shielded Labs indicated that it was unlikely the vulnerability had been exploited. ZODL, another key organization, stated there was no impact on user funds, total ZEC supply, or user privacy due to the bug.
Even with this reassuring information, the incident raised concerns regarding user confidence in Zcash. The Orchard pool's shielded design, which inherently hides transaction details, protects users' privacy but also makes it difficult for them to personally verify if any counterfeit ZEC was created in the pool.
#What is the Ironwood Upgrade?
To address the trust issues stemming from this incident, Zcash developers are currently working on an upgrade known as Ironwood. This proposed enhancement is being developed by ZODL in partnership with Tachyon, Valar Group, the Zcash Foundation, and Shielded Labs.
The Ironwood upgrade plans to retain the existing Orchard protocol while fixing the recent vulnerability. It will also introduce formal verification processes and independent audits to minimize potential risks of future bugs.
Another crucial aspect of the Ironwood proposal is to close the current Orchard pool to new deposits and internal transactions. Funds will only be able to exit through a mechanism known as a turnstile. This innovative tool is designed for transferring assets between pools and will ensure users cannot withdraw more ZEC than they originally deposited. Therefore, users can confirm that the circulating supply of ZEC remains accurate without having to wait for a complete migration from Orchard.
Once the Ironwood upgrade is implemented, users operating a node will have the ability to verify the validity of the circulating supply by reviewing the balances of active pools.
ZODL aims to have the Ironwood upgrade activated by the end of July 2026, following zcashd reaching its end of support at block height 3,417,100. However, this timeline is contingent upon adequate testing, thorough reviews, and effective collaboration among wallets, node operators, exchanges, mining pools, and all relevant infrastructure providers.
