Zcash plans to launch the NU7 mainnet upgrade on November 5, reducing the block time to 25 seconds.

The Zcash development team plans to activate the NU7 mainnet upgrade on November 5, 2026. The testnet is expected to launch on October 6, and the mainnet upgrade activation height will be finalized on October 20 based on testnet performance. NU7 proposes to reduce the target block interval from 75 seconds to 25 seconds, disable V4 transactions, and integrate the Network Sustainability Mechanism (NSM), while retaining the existing halving schedule. In the ZEC holder vote, 98.9% supported retaining the halving mechanism, and 99.9% of votes weighted by ZEC holdings supported shortening the block interval.
