Zcash Activates NU7 Upgrade on Nov 5, 2026: What It Means for ZEC Holders

The Zcash network is set to activate the NU7 upgrade on November 5, 2026. This upgrade involves a hard fork, which means that older software will no longer be compatible with the new rules.

NU7 consists of three components: the target block spacing drops from 75 seconds to 25 seconds, version 4 transactions are switched off, and the Network Sustainability Mechanism is added. However, according to Zcash core developer Sean Bowe, this upgrade brings no new transaction formats, and the changes are not meant to affect wallets in any material way.

The only people who need to take action are those who run infrastructure themselves, such as full nodes, indexers, or block explorers. The rest of the ZEC holders do not need to move their coins, swap them, or pull them off an exchange.
