Zcash sets July 28 date for Ironwood upgrade replacing Orchard pool
The Ironwood activation is scheduled for height 3428143, and an accounting checkpoint in the new setup could help determine whether any counterfeit Zcash were created via the Orchard bug.
Zcash has set a July 28 mainnet activation for its Ironwood network upgrade, which will replace the privacy-focused blockchain’s Orchard private transaction pool after a bug discovered in May, Cointelegraph reported.
Cointelegraph said Ironwood will close the current Orchard pool, block new activity in it, and route any funds leaving Orchard through an accounting checkpoint before entering Ironwood, a process intended to produce evidence on whether any counterfeit Zcash tokens were created through the Orchard bug.
The upgrade date is one week later than an earlier July 21 target, with Zcash core developer Sean Bowe saying Ironwood activation has been tagged for NU6.3 at block height 3428143, approximately July 28 at 8AM EST.
Cointelegraph added that ZEC fell 50% to $299.25 after the Orchard bug disclosure on June 3, later partially recovering to around $492.61, and noted Zcash has now issued more than 80% of its maximum 21 million ZEC supply.
