Zcash founder Zooko introduced the Ironwood network upgrade

Zooko, founder of Zcash, wrote about the upgrade of the Ironwood network. The upgrade, which is expected to activate on 28 July, will contain Orchard's privacy pool, which has a potential risk of forgery of ZEC, and will activate the restored new privacy pool. Earlier, researchers had discovered that the Orchard circuit had a critical loophole that could lead to the forgery of the ZEC, but the official view was that it was unlikely that the loophole had been exploited。
