Zcash has activated Network Upgrade 7, which reduces block times from 75 to 25 seconds and will help fuel a long-term security reserve. However, the move also froze about $16 million worth of ZEC that will remain inaccessible in an outdated shielded pool. Zcash has officially completed its latest network upgrade, Network Upgrade 7 (NU7), activating at block 3,543,405 . The major milestone introduces a shift to 25-second block target times alongside the mainnet deployment of the Network Sustainability Mechanism (NSM), designed to address long-term tokenomics and security as block subsidies decline. With NU7, Zcash transitions block target times from 75 seconds to 25 seconds. To keep total daily ZEC issuance consistent with the existing schedule, the block reward has been proportionally adjusted to 0.52083333 ZEC per block.
