The Zcash network has successfully implemented its Network Upgrade 7 (NU7) on the mainnet. This upgrade introduces several significant technical changes, most notably reducing the target block time from approximately 75 seconds to 25 seconds. It also implements the Network Sustainability Mechanism (NSM), which redirects 60% of transaction fees into a reserve to fund future mining rewards starting in 2031, while maintaining the total supply cap of 21 million ZEC.
