The NU7 upgrade is set for block 3,543,405, expected around Nov. 5, and would cut block times to 25 seconds from 75. It would also route 60% of transaction fees into a reserve and retire the old Sprout pool. ZEC rose about 11% over 24 hours, mostly during U.S. trading on Tuesday.
The headline feature of Zcash's next upgrade is speed. The features with more bearing on holders are a change in where transaction fees go and the retirement of the network's oldest shielded pool.
Zcash developers have agreed to activate the NU7 network upgrade at block 3,543,405, which is expected to arrive around Nov. 5. The target block is listed on a public dashboard run by Zakura. The proposal setting the height has been approved but still has to be merged into the protocol specification and shipped in node software before it is final. NU7 has been running on Zcash's test network since early October.
ZEC rose about 11% over 24 hours, most of it during U.S. and European trading hours on Tuesday, from about $1,130 early that morning to about $1,267 by 5 p.m. Eastern. It was roughly flat through the Asian session and stood at $1,269.10 at about 4:46 a.m. Eastern on Wednesday, giving it a market value of about $20.9 billion.
What changes
The upgrade would cut Zcash's block time to 25 seconds from 75, so transactions confirm three times as fast. It would also send 60% of transaction fees to a reserve, known as the Network Sustainability Mechanism, that is expected to begin paying out around February 2031.
NU7 also retires Sprout, Zcash's original shielded pool. Funds still held there when the upgrade activates become unspendable, which makes the activation date a deadline for anyone with coins left in it.
The fee change bears more on how the token captures value. Faster blocks improve the experience for users. Redirecting fees into a reserve changes the flow of income in the network, though with payouts not expected to start for about four years, the effect is long-dated.
Where the price stands
ZEC has had a large run this year. At $1,269, it is about 86% above its 200-day average of about $682 and roughly in line with its 50-day average of about $1,262. It is also about 25% below its high of $1,693, set on Sept. 26.
That leaves the upgrade news landing on a token trading at nearly twice its 200-day average, and one that has been consolidating near its 50-day level.
Market implications
One reading is that NU7 is a fundamental improvement. Faster payments and a fee reserve make the network more useful and change how value accrues, supporting demand.
A second reading is that the upgrade is a trigger for a crowded trade rather than its driver. Momentum has carried ZEC this year, and dated catalysts often draw buyers who leave once the event passes.
A third reading is that regulation caps the upside. Privacy features can limit listings on regulated exchanges and institutional access.
What to watch
The merge of the activation height into the specification; node software releases; the share of nodes upgraded ahead of the target block; any delay to the Nov. 5 estimate; and exchange support for the upgrade. A software release on schedule would turn the estimated date into a firm one.
