Zcash will activate its Ironwood network upgrade on July 28 to replace the vulnerable Orchard shielded pool after a security flaw was found that could have allowed counterfeit ZEC creation. The upgrade introduces an accounting checkpoint for funds leaving Orchard, helping detect any fake coins if the bug was exploited. Despite a sharp price drop after the flaw's disclosure, ZEC has partially recovered, and over 80% of its maximum supply has been issued. The upgrade confirms Zcash's ongoing efforts to secure its privacy-focused transactions and maintain network integrity.
