Zcash activates Ironwood mainnet upgrade, halts new inflows to Orchard
Zcash has activated the Ironwood upgrade on its mainnet and halted new inflows into the existing private pool, Orchard. Zcash Open Development Lab said the upgrade went live at block height 3,428,143. Orchard is shifting effectively to a withdrawals-focused state, with remaining funds required to pass through a “turnstile” structure to move to Ironwood. The upgrade also targets an Orchard vulnerability reported in late May, with no confirmed signs of exploitation.
