Zcash developers propose Ironwood, a network upgrade designed to restore trustless verification of ZEC supply after the Orchard vulnerability exposed risks around undetectable counterfeiting

Block 3,363,426 was the emergency line: Orchard actions were rejected on June 2, NU6.2 re-enabled the corrected circuit on June 3, and Ironwood would make the old pool a quarantined liability bucket. If counterfeit Orchard notes exist, the turnstile migration should either trap them or create public evidence; if they do not, each clean exit shrinks the unresolved overhang. ZEC trades less like a privacy coin until that clears, because exchanges and wrappers price NAV uncertainty harder than patched-code assurances.
