Svmuu News: Zcash core developer Sean Bowe posted on X stating that the block height for the Zcash Ironwood mainnet activation has been determined and marked. All major organizations have committed to activating the NU6.3 upgrade at block height 3,428,143, which is expected to occur at 8:00 p.m. Beijing Time on July 28. This upgrade stems from a previous vulnerability in the Orchard pool, which could have allowed attackers to mint unlimited amounts of counterfeit ZEC. Due to the Orchard pool’s privacy features, the team was unable to determine whether any counterfeit ZEC had been minted before the vulnerability was patched.
