Zcash has confirmed a firm activation date for its Ironwood network upgrade, with the overhaul set to go live on July 28 at approximately 8AM EST. The upgrade, formally designated NU6.3, will activate at block height 3428143 and closes the chapter on a critical vulnerability discovered in May in the network’s primary private transaction pool.
Announced in June, the Ironwood upgrade shuts down the existing Orchard shielded pool, blocks any new transactions from entering it, and establishes a replacement private pool. The key wrinkle: every ZEC leaving Orchard must pass through an accounting checkpoint before it can enter the new pool. That checkpoint mechanism could yield forensic evidence about whether the so-called ‘infinity’ bug was ever exploited to mint counterfeit ZEC tokens.
