Zcash has finalized its Ironwood upgrade plan, aiming for activation in July.

CoinFeed reported on June 9th that, according to The Block, Zcash developers have reached a consensus on rule changes for the upcoming Ironwood upgrade, aiming for activation in July. This upgrade stems from a previous Orchard pool vulnerability—a vulnerability that could allow attackers to mint an unlimited number of counterfeit ZECs. Due to the privacy nature of Orchard pools, the team could not determine whether counterfeit ZECs had been minted before the vulnerability was patched. The Ironwood upgrade will take two core measures: first, introducing a new privacy pool using the Orchard protocol, with the old pool being phased out; second, adding a control flag to the zero-knowledge proof circuit, which, when enabled, disables the ability to transfer funds to other users within the pool while retaining change functionality. After the upgrade is activated, this flag will be enabled for the old Orchard pool, and transfers initiated by users to old pool addresses will be automatically redirected to the new pool.
