Zcash is cutting block times. What changes for users and miners?

Zcash’s NU7 upgrade will cut the target time between blocks from 75 seconds to 25, giving deposits a chance to confirm sooner while leaving exchanges to decide when to credit them. The upgrade also changes what miners earn from transactions, with 40% of fees going to miners and the remaining 60% set aside for future rewards. Summary NU7 takes effect at block 3,543,405, so the switch depends on when miners reach that height. Target block spacing falls from 75 seconds to 25, but exchanges can change how many confirmations they require before crediting deposits. The subsidy per block falls by about 67%, keeping scheduled daily issuance steady as the network produces blocks three times as often. Miners keep 40% of transaction fees, with the remaining 60% set aside for reissuance scheduled to begin at block 8,939,664. Zcash retains its 21 million ZEC supply cap, while funds left in the legacy Sprout pool become unspendable after activation. Zcash has scheduled its NU7 upgrade for block 3,543,405, when the network will cut its target time between blocks from 75 seconds to 25 and start setting aside most transaction fees for future mining rewards.
