Zcash NU7 upgrade recycles 60% of fees to fund future block rewards

Zcash activated its NU7 upgrade, which introduces a Network Sustainability Mechanism that recycles 60% of transaction fees to help fund future block rewards. The mechanism will reissue removed ZEC starting in 2031 while staying within the 21 million supply cap. The change is a structural tweak to Zcash's long-term incentive model, and the community is still debating its development fund, so the price impact is likely limited but worth watching for ZEC holders.
