Woofun AI reports that the Zcash network has locked in July 28 as the activation date for the Ironwood upgrade, a critical patch designed to neutralize the 'infinity' bug identified within the Orchard private transaction pool. This definitive timeline was established by Zcash core developer Sean Bowe, who confirmed the commitment of major organizations to the NU6.3 protocol change, effectively overriding earlier suggestions from Shielded Labs to delay the rollout due to preparation concerns for ecosystem participants. The upgrade serves as the primary technical response to the vulnerability discovered in May, ensuring the integrity of the privacy-focused blockchain’s main private transaction mechanisms.

Structurally, the Ironwood update functions by closing the current Orchard pool and establishing a new private pool, thereby halting all new activity in the compromised environment. Funds migrating from the old pool to the new one must traverse a strict accounting checkpoint, a mechanism intended to generate forensic evidence regarding the existence of counterfeit Zcash (ZEC) tokens. As noted by Shielded Labs in June, this migration forces a hypothetical counterfeiter into a binary dilemma: attempt to move illicit funds and risk immediate exposure, or abandon them and forfeit future liquidity. The activation is scheduled for block height 3428143, occurring at approximately 8AM EST on July 28, which represents a one-week postponement from the initial target of July 21.

Market sentiment reflects the volatility surrounding the security incident, with ZEC prices plummeting 50% from $602.68 to $299.25 immediately following the bug disclosure on June 3.

However, the asset has since staged a partial recovery, trading at $492.61 at the time of writing. Per Woofun AI, the network also achieved a significant supply milestone this week, with more than 80% of the maximum 21 million ZEC cap now in circulation. Data from ruZCASH posted on Monday confirms that the total supply has reached 16,806,723 ZEC, highlighting the maturity of the monetary policy despite recent technical turbulence.

The confirmed activation marks a decisive step toward stabilizing the Zcash ecosystem, balancing the urgent need for security fixes with the operational readiness of exchanges, mining pools, and wallets. By enforcing the accounting checkpoint, the network aims to permanently resolve the Orchard vulnerability while providing transparency on potential exploitation. This coordinated effort underscores the resilience of the development team in managing high-stakes protocol upgrades under market pressure.
