Zcash activated NU7 early Friday, introducing a mechanism that removes 60% of transaction fees from circulation to fund future block rewards. The network sustainability mechanism will begin reissuing these funds in 2031, while maintaining the existing halving schedule and the 21 million ZEC supply cap. The Zcash Foundation said NU7 reduces the target block interval from 75 seconds to 25 seconds. Separately, holders and community groups will vote this month on the share of the development fund allocated to the Zcash Community Grants program, with voting scheduled for November 16–30.
