According to Wu, Zcash founder Zooko shared a post introducing the Ironwood network upgrade. This upgrade is expected to activate on July 28, sealing off the Orchard privacy pool that carries potential risks of counterfeit ZEC and enabling a new, fixed privacy pool. Previously, researchers discovered a critical vulnerability in the Orchard circuit that could potentially lead to counterfeit ZEC, but the official statement suggests it’s unlikely the vulnerability has been exploited. https://(wublock123.com)/news/zcash-activates-ironwood-upgrade-jul-28-fix-zec-counterfeit-vulnerability-64882
