Zcash Speeds Up Testnet

Key Summary

Zcash has activated its NU7 network upgrade on the public testnet at block height 4,465,026, marking the first live environment where the protocol overhaul can be exercised. The upgrade, which ships through Zebra 7.0.0-rc.0, aims to reduce block times from 75 seconds to 25 seconds, introduce a fee-recycling system, and retire a shielded transaction format. The Network Sustainability Mechanism directs 60% of transaction fees toward supporting the network's longevity. A mainnet decision is scheduled for October 20, 2026, with a target activation date of November 5, 2026.
