Zcash Completes Ironwood Upgrade with Consensus Rule Changes, Expected to Activate in July

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 on top of the Orchard protocol to replace the old Orchard pool and will adjust the mechanism to ensure the ZEC circulating supply remains constrained.

According to the developers' plan, Ironwood will introduce a "flagging" mechanism between the new and old Orchard pools, restricting the old pool from receiving new transactions while allowing for change outputs, serving as a privacy measure. After the upgrade is activated, the old Orchard pool will be prohibited from receiving new inputs, 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.
