Zcash has set the NU7 mainnet activation height at block 3,543,405, scheduled for November 5, 2026. TokenPost reported that the upgrade will reduce the target block spacing from 75 seconds to 25 seconds, effectively tripling transaction speed and improving network scalability.

The upgrade introduces new consensus rules regarding legacy Sprout pool balances, which will become unspendable once the activation occurs. Technical details indicate that while block rewards will be adjusted for more frequent intervals to maintain the current issuance schedule, the proposal also includes directing 60% of transaction fees out of circulation.
