Zcash Plans to Activate NU7 Mainnet Upgrade on November 5, Reducing Block Time to 25 Seconds

By: cointelegraph.com|2026/09/18 04:59:23

The Zcash development team plans to activate the NU7 mainnet upgrade on November 5, with relevant organizations and engineering teams reaching an agreement. This upgrade will be activated on the testnet on October 6. The team will evaluate the performance of the NU7 testnet on October 20 before finalizing the mainnet upgrade and activation block height. The upgrade aims to shorten the target block interval from 75 seconds to 25 seconds, deprecate version 4 transactions, and integrate a network sustainability mechanism. The chosen mechanism will retain the Zcash halving cycle, with previously removed supply being reintroduced starting February 20231. NU7 does not introduce new transaction formats, having limited impact on wallets, but full nodes, indexers, and block explorers may require adjustments.
