Zcash Proposes 'Ironwood' Upgrade in Response to Counterfeiting Vulnerability

In response to a recently uncovered counterfeiting vulnerability within the Orchard pool of Zcash (ZEC), a new network upgrade named 'Ironwood' has been proposed by Shielded Labs and associated entities. This upgrade aims to facilitate independent verification of the cryptocurrency's circulating supply, addressing critical security concerns. The proposed Ironwood upgrade introduces a turnstile mechanism, which is designed to enhance transparency and security by verifying the integrity of shielded transactions. The implementation of this upgrade is scheduled for the end of July, marking a significant step towards bolstering the robustness of the Zcash network against potential threats.
