AI overview

Zcash developers confirmed the NU7 upgrade will activate on November 5, tripling payment speed by compressing block time from 75 to 25 seconds. The upgrade permanently removes the Sprout privacy system, rendering any remaining Sprout funds unspendable. It also removes 60% of fees from each block, with a plan to return these fees to miners starting February 2031 while preserving the existing halving schedule every 50 years.
