Zcash Ironwood Upgrade Locked In for July 28 After Orchard Pool Bug
Zcash's Ironwood upgrade is set for July 28, addressing an 'infinity' bug in the Orchard pool. The upgrade will replace the pool and require funds to pass through an accounting checkpoint, potentially exposing counterfeit ZEC. ZEC's price dropped 50% post-bug disclosure but has since partially recovered to $492.61. The circulating supply reached 16,806,723 tokens, 80% of its 21 million hard cap.
