Zcash NU7 Upgrade Activates on Testnet with Faster Blocks
Zcash (ZEC)

cryptocurrency.com.tr reports that Zcash has activated its NU7 upgrade on the public testnet at block 4,465,026. This activation shifts the target block interval from 75 seconds down to 25 seconds. If services maintain a three-confirmation policy, the target wait time drops from 225 seconds to approximately 75 seconds.
The network is currently using valueless coins to allow developers and infrastructure operators to rehearse the upgrade. NU7 also redirects 60% of transaction fees into a future-reward reserve. Per-block rewards are cut to preserve the ZEC issuance schedule, and Sprout transactions are disabled.
This change marks a shift from the previous 75-second target to the new 25-second goal. The upgrade is currently a testnet trial rather than a mainnet change. Zcash (@zcash) confirmed the activation, highlighting the move to disable version 4 transactions.
How the market reacted
Whalio's own Binance spot order flow for ZEC, measured when this story was written up on 5 October 2026. Not the outlet's figures.
ZEC is trading at $1,352.37 with a 24-hour buy ratio of 55.1%, indicating that buyers are currently in control. However, the 1-hour buy ratio has dropped to 45.6%, and the 4-hour ratio is even lower at 38.2%, suggesting that short-term buying pressure is fading. The 24-hour volume delta is positive at $9,866,928, but the 1-hour delta is negative at -$622,575. This means that while net buying has occurred over the day, recent trades have been predominantly selling. The cumulative volume delta (CVD) for the 24-hour close is -$15,093,889, showing that more money has flowed out than in over the full day. Net buying occurred for 12 of the last 24 hours.
The latest daily buy ratio of 52.9% sits at the 82nd percentile of the last 322 days, against a median of 50.2% - stronger buying than most days.
