$ZEC has a detail here worth noticing.
Zcash's NU7 Upgrade Goes Live, Recycling 60% of Fees to Fund Future Block Rewards - Decrypt In brief Zcash's NU7 upgrade went live early Friday, activating a mechanism that removes 60% of transaction fees from circulation to fund future block rewards. Zcash's NU7 network upgrade went live at block 3,543,405 early Friday, activating the Network Sustainability Mechanism (NSM), a change designed to help pay for the privacy coin's security as its block rewards shrink. The NSM tackles a problem Zcash inherited from Bitcoin : whether, as block subsidies decline with each halving, transaction fees alone will be enough to pay miners to secure the network. Under the mechanism , 60% of transaction fees will be removed from circulation and gradually reissued through future block rewards, while preserving the 21 million ZEC supply cap. "It should be difficult to change the protocol, and the process should resist capture by any single organization, group, or influential individual." The upgrade arrives as Zcash's community debates the future of Zcash Community Grants (ZCG) and its share of the Dev Fund, the slice of block rewards that pays for development.
