Zcash's NU7 Vote Could End the Halving for Good

Highlights

Zcash's NU7 coinholder vote closes September 14 at 19:00 UTC
The central question: replace scheduled halvings with a smooth issuance curve under draft ZIP 234
A second ballot item would cut Zcash's block interval from 75 seconds to 25 seconds
ZEC trades near $1,093, its highest level since 2018, now the 10th-largest crypto by market cap

Zcash has run on the same monetary script as Bitcoin since launch: block rewards that get cut in half on a fixed schedule, with the next one due around late 2028. This week, the people who actually hold ZEC get to vote on tearing that script up.

The NU7 network upgrade vote closes September 14 at 19:00 UTC, and its headline question is whether to replace periodic halvings with a smooth issuance curve. Under the draft proposal, known as ZIP 234, miners would instead receive a fixed fraction — 0.0000004126 — of the remaining unissued coin supply in every block, which works out to roughly 1.68 ZEC per block at current supply versus the 1.5625 ZEC paid today. Practically, that means a small increase in near-term issuance now in exchange for erasing the sudden 50% supply-growth cut that a halving otherwise delivers overnight. Voters can also choose to keep the existing halving schedule while reissuing coins that would otherwise be permanently removed from circulation, or reject the smoothing proposal entirely and leave NU7's issuance mechanics untouched.

Nothing on the ballot changes Zcash's hard cap on total supply — that number stays fixed regardless of the outcome. What's actually being decided is the shape of the curve on the way there: a jagged one with periodic 50% cuts, or a smoother one that avoids the reward cliff miners and the broader market have had to absorb at every halving to date.

The vote isn't limited to that single question. Four other items share the ballot: when coins removed from circulation under the old schedule should start being reissued, if smoothing passes (options range from immediately to as late as February 2031); when to retire the long-dormant Sprout shielded pool; whether to cut Zcash's block interval from 75 seconds to 25 seconds, a change that would make blocks arrive roughly three times more often; and whether NU7 should ship on schedule even if some planned features aren't finished in time, or wait for full completion. Only holders of shielded, spendable ZEC sitting in the newer Ironwood pool are eligible, and eligibility is fixed to a snapshot at block height 3,459,350 — a design that rewards holders who were already using Zcash's privacy features rather than opening the vote to anyone who acquires ZEC after the fact.

Even a clean pass doesn't flip a switch immediately. CryptoSlate reported that the vote is advisory rather than binding at the protocol level — developers still have to write, test and ship the corresponding code before any of it takes effect on mainnet, meaning the practical rollout could stretch well beyond this week's deadline regardless of how the vote lands.

The timing lines up with a broader run for ZEC. Privacy coins have been the standout sector of 2026, up 213% and outpacing every other corner of the market, and Zcash has been the poster child of that move. Grayscale's repeated amendments to its Zcash ETF filing have added a steady drip of institutional-interest headlines on top of the rally, and ZEC's climb toward $1,093 marks a fresh high last seen in 2018, pushing it into the top ten cryptocurrencies by market cap. Short sellers betting against the move have already booked tens of millions in losses as the rally has repeatedly outrun their positions.

Whichever way the vote breaks, it puts Zcash in a position few privacy coins have faced: a real market capitalization, genuine institutional attention, and a live decision about its own monetary policy playing out in public, one wallet balance at a time.

FAQ

Does the NU7 vote change how many ZEC will ever exist?
No. The total supply cap is unchanged either way — the vote only decides the pace and shape of issuance leading up to that cap, not the cap itself.

Who is allowed to vote on NU7?
Only holders of shielded, spendable ZEC in the Ironwood pool as of a fixed snapshot at block height 3,459,350 can participate, which excludes ZEC held in transparent addresses or acquired after that snapshot.

Is the outcome of the vote automatically enforced?
No. The vote is advisory. If smoothing or the other proposals pass, developers still need to write, test and deploy the corresponding code before it takes effect on the network.

Would smoothing eliminate the halving scheduled for 2028?
Yes, if adopted, ZIP 234's smooth issuance curve replaces the periodic halving model entirely, including the one otherwise due around late 2028.
