Zcash Activates NU7 on Testnet, Cutting Target Block Times to 25 Seconds

Zcash’s NU7 upgrade activated on the network’s public testnet at block 4,465,026 on October 4, 2026, moving the planned protocol changes into a live pre-mainnet environment. The upgrade’s most visible change is a reduction in target block spacing from 75 seconds to 25 seconds, intended to cut the average wait for a first confirmation by threefold. The public-testnet deployment is a rehearsal rather than a mainnet launch. Developers plan to assess its performance before making a final decision on whether to proceed with a proposed November activation.
