[Zcash Completes Ironwood Upgrade Plan, Expected to Activate in July] BlockBeats News, June 9, Zcash developers have completed the consensus rule changes for the Ironwood upgrade and plan to activate the upgrade in July. This upgrade will introduce a new privacy transaction pool based on the Orchard protocol to replace the old Orchard pool and ensure constraints on ZEC circulating supply through mechanism adjustments. According to the developers' plan, Ironwood will implement a 'flag bit' mechanism between the new and old Orchard pools to restrict the old pool from receiving new transactions while allowing the generation of change, serving as a privacy protection measure. After the upgrade is activated, the old Orchard pool will be prohibited from receiving new deposits, and wallets will route new transactions to the new pool. Developers stated that this design, combined with the existing turnstile mechanism, aims to ensure that ZEC circulating supply cannot be minted infinitely and allows users to migrate funds to the new pool to reduce potential risks.
