Zcash activates NU7 upgrade on testnet ahead of November rollout

Zcash NU7 upgrade blockchain testnet activation block time

Zcash has activated its NU7 network upgrade on its testnet, marking a critical step toward a planned mainnet rollout. The upgrade was confirmed to be live at block 4,465,026 on October 4.

A primary feature of the NU7 upgrade is the reduction of target block spacing from 75 seconds to 25 seconds, which is intended to improve transaction speeds and user experience. The upgrade also introduces a Network Sustainability Mechanism; according to ZIP 235, 60% of transaction fees per block will be directed to a reserve fund to support future block rewards, while miners retain 40%.

Users holding ZEC in the legacy Sprout shielded pool must move their funds before the mainnet activation, as the upgrade will disable version 4 transactions. Failure to move these funds could render them unspendable.

Zcash developers are scheduled to review testnet performance and make a final decision regarding mainnet activation on October 20. The current target for the mainnet launch is November 5.
