About ZcashIronwood

Zcash activated the Ironwood hard fork at block 3428143. The trigger: in late May, researchers found an Orchard zk-circuit bug that could mint fake ZEC untraceably. It had existed since the pool launched in 2022, and the privacy design makes past exploitation cryptographically unprovable (no evidence found, though ZEC once fell nearly 50%). The fork shuts old-pool deposits and adds a rate-limiting turnstile so every exit clears a ledger check, making ZEC supply auditable for the first time.
