Zcash has rolled out the Ironwood upgrade on its mainnet, delivering a key fix to ongoing concerns about verifying the ZEC supply. This update brings a new privacy pool designed to provide independent confirmation of the total coins in circulation, strengthening the network’s security posture.
What Changed with Ironwood
Activated at mainnet block 3,428,143, the Ironwood upgrade replaces the prior Orchard privacy pool with enhanced safeguards. Transfers from Orchard to Ironwood now require passing through a transition mechanism built to detect any supply anomalies and maintain strict supply integrity. This step responds to a vulnerability discovered in the Orchard pool back in May, which was patched quickly but raised questions about the reliability of verifying ZEC's supply.
Implications for Users and the Network
Users holding ZEC in the Orchard pool must migrate assets to the new Ironwood pool. Wallets supporting Ironwood will offer straightforward migration tools without needing new addresses or wallets, preserving user convenience. The upgrade also integrates formal verification techniques and independent security audits, aiming to prevent future weaknesses related to supply verification. While no evidence suggests the earlier vulnerability was exploited, Ironwood’s release provides a stronger, more transparent foundation for the coin’s privacy and supply assurance.
