Zcash Seals $1.7 Billion Shielded Pool After Ironwood Upgrade: Orchard Bug Reported, Not Officially Confirmed

CoinDesk has reported that Zcash activated its Ironwood upgrade, sealing the Orchard shielded pool which held approximately 3.66 million ZEC, valued at about $1.7 billion. The upgrade was prompted by the discovery of a previously undisclosed bug in Orchard’s proof circuit, which could have enabled the creation of counterfeit ZEC without onchain traces. The Ironwood upgrade introduces a turnstile mechanism that restricts withdrawals to the amount verifiably deposited, aiming to prevent any unaccounted coins from leaving the pool. These developments are not officially confirmed and remain based on media reporting.
