Zcash News: NU7 Activates Early on Testnet, Block Time Falls to 25s!
Zcash News is about a date and a number. The official Zcash account says Network Upgrade 7 arrives on November 5 and cuts block time from 75 seconds to 25.
The same upgrade disables Sprout-transactions, so Sprout ZEC holders are told to move first. This crypto news today report sticks to what that one news says.
Key Takeaways
Zcash says Network Upgrade 7, dated November 5, cuts block time from 75-sec to 25-sec and disables Sprout-transactions.
Sprout ZEC should migrate to Sapling before activation, per the update.
The update gives no wallet steps, fee changes, or mainnet confirmation, and a 500-block interval falling to about 3.5 hours at 25 seconds is derived from arithmetic.
What Did Zcash Announce About NU7?
The @Zcash update names Network Upgrade 7 and the date November 5. It says the upgrade reduces block time again, from 75 seconds to 25 seconds, and disables Sprout-transactions.

The word "again" points back to the Blossom upgrade of 2019, which the update recalls first.
The latest news ends with one instruction: Sprout-ZEC should migrate to Sapling before activation.
How Fast Will Blocks Become Under NU7?
Block-time is the target gap between new blocks. The source gives three values: 150-sec before Blossom, 75-sec after it, and 25 seconds under NU7.
That is a 66.7% cut from 75-sec, and an 83.3% cut from 150 seconds (derived).
In a day, the chain targets about 576 blocks at 150-sec, 1,152 at 75 seconds and 3,456 at 25 seconds (derived). So NU7 would triple the daily block-target.
How Does NU7 Compare with Blossom?
The update uses Blossom as a precedent. In 2019 that upgrade halved block time from 150 to 75-sec and, per the source, cut the sprout-to-sapling migration interval in half. Network update 7 repeats the pattern with a larger step, from 75 to 25-sec.
Why Does Block Time Change the Sprout-Migration Interval?
The update measures the Sprout-to-Sapling pool migration interval in blocks, 500 of them. So a shorter block time shortens the interval in hours.
The Zcash News says Blossom cut that interval from 20.8 hours to 10.4 hours, and the source puts the later figure at about 10.42 hours.
What Should Sprout ZEC Holders Do?
The Zcash news says Sprout ZEC should migrate to Sapling before activation. It also says NU7 disables Sprout-transactions.
Together, those lines make the migration a deadline task, tied to November 5. The source gives no steps, wallet names, or fees for the move.
Holders should check Zcash's official guidance before acting. From October 25, the date is 11 days away (derived).
What Does the Zcash Post Leave Out?
The source does not say whether NU7 is live on any network. It gives no data on fees, confirmation times, or node needs under 25-second blocks.
It names no wallet changes and no support window for Sprout. Readers of the latest crypto news should treat a date and a block time as plans until Zcash announces activation.
Conclusion
Zcash News on NU7 is a plan with a date and two changes: faster blocks and the end of Sprout-transactions. The update gives holders one task, moving Sprout ZEC to Sapling. How smoothly that goes depends on guidance the update does not include.
