BlockBeats News, June 9th, Zcash developers have completed the consensus rule change 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 will adjust the mechanism to ensure that the ZEC circulating supply remains constrained.

According to the developers' plan, Ironwood will introduce a "flagging" mechanism between the new and old Orchard pools to restrict the old pool from receiving new transactions while allowing for change outputs to be generated as a privacy 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, is used to ensure that the ZEC circulating supply will not be infinitely minted and allows users to migrate funds to the new pool to reduce potential risks.
