Zcash completes Ironwood upgrade plan, expected to activate in July.

According to Mars Finance, Zcash developers have completed the consensus rule changes for the Ironwood upgrade and plan to activate it in July. This upgrade will introduce a new privacy transaction pool based on the Orchard protocol to replace the old Orchard pool, and will ensure that the circulating supply of ZEC remains constrained through mechanism adjustments. According to the developers' plan, Ironwood will introduce a "flag" mechanism between the old and new Orchard pools, restricting the old pool from accepting new transactions while allowing change to be generated, thus serving as a privacy protection measure. After the upgrade is activated, the old Orchard pool will be prohibited from accepting new deposits, and wallets will route new transactions to the new pool. The developers stated that this design, combined with the existing turnstile mechanism, is used to ensure that the circulating supply of ZEC is not infinitely minted and allows users to migrate funds to the new pool to reduce potential risks.
