Zcash activates NU7 with 25-second block targets
The Block reports that Zcash’s NU7 upgrade is live on mainnet. Under the NU7 specification, the target interval between blocks changes from 75 seconds to 25; this is a protocol target, not a guarantee of a particular transaction speed. The upgrade also invalidates version 4 transactions, the only format that can carry Sprout transfers, so funds still in the legacy Sprout pool are unspendable under the new rules. Cointelegraph estimates their value at about $15 million and says a future network upgrade could potentially restore access, but no such remedy is confirmed. Decrypt reports that NU7 activates the Network Sustainability Mechanism, under which ZEC removed from circulation is to be reissued beginning in 2031 within the 21 million supply cap. The specification says the upgrade does not raise that cap.
