Zcash Activates Ironwood Network Upgrade July 28, Developers Issue Orchard Migration Guidance

cryptoblockchains 21 posts · 5 accounts

Zcash activates its Ironwood network upgrade on July 28, introducing a new shielded pool and a verification mechanism that guarantees total ZEC supply remains correct. Developers are advising holders to delay migrating funds from the existing Orchard pool and to plan transfer strategies carefully before initiating any movement.

Privacy safeguards form the core of the guidance, which warns that lightwallet servers can expose IP addresses linked to holdings. Nym provides a free one-month VPN trial to participants verifying a shielded wallet, while wallet vendors including Zodl have published migration instructions and recommended customers wait.
