Zcash holders delivered near-unanimous backing for the network's next major upgrade, NU7, with roughly 2.4 million ZEC of about 3.6 million eligible participating in a privacy-preserving governance vote. Of those, 99.9% backed cutting block times from 75 seconds to 25, and 98.9% voted to preserve Zcash's bitcoin-style halving schedule rather than moving to a more gradual new-coin issuance model. The ballot ran only through Ironwood, Zcash's newest shielded transaction pool, so individual holder balances stayed hidden even as weighted votes were tallied.
Why it matters
The turnout was a structural jump from Zcash's earlier NU7 sentiment poll in February, which drew just 7.25% of circulating ZEC and exposed sharp disagreements between coinholders and the Community Advisory Panel. This round replaced that system to give shielded balances much stronger privacy guarantees, with ballots encrypted and split into 16 pieces before counting so validators could add the result without reconstructing who voted what.
That setup removed the usual chill on whale participation. In a normal token vote, a wallet casting 500,000 votes effectively tells the world it controls 500,000 tokens and which side it backed. Zcash's system counted that economic weight without publishing the holder's balance or choice.
Market impact
Cutting block times from 75 to 25 seconds triples throughput and pushes Zcash confirmation latency closer to retail card-network speeds. The vote also locked in a 96.6% mandate to delay reissuing ZEC collected through the Network Sustainability Mechanism until February 2031, letting removed supply accumulate while halvings continue cutting new issuance. Separately, new Zcash software has cut proof-generation times on mobile from over three seconds to under 200 milliseconds in tests, with Zakura and Project Tachyon targeting much higher private-transaction throughput. About 99.3% of voters wanted NU7 shipped as soon as possible, with any unbuilt features dropped by a Sept. 30 readiness deadline rather than waiting on the full approved slate.
Frequently asked questions
-
What did Zcash holders actually vote on?
Holders voted on the scope of NU7, Zcash's next major network upgrade. The ballot covered block times, the halving schedule, NSM fee reissuance timing, and the shipping deadline.
-
How many ZEC participated in the vote?
About 2.4 million ZEC voted out of roughly 3.6 million eligible at the snapshot, a turnout of around two-thirds. The 1 million ZEC organizer-set threshold was cleared easily.
-
How does Zcash's shielded voting keep balances private?
Only ZEC in Ironwood, Zcash's shielded transaction pool, could vote. Ballots were encrypted and split into 16 pieces before counting, so validators could tally results without reconstructing who voted what.
-
Why is cutting block times from 75 to 25 seconds significant?
Shorter block intervals mean users see transactions confirmed roughly three times faster, putting Zcash closer to retail card-network confirmation latency. The 99.9% mandate gives NU7 developers a clean runway to ship.
-
What did the vote decide about Zcash's halving schedule?
98.9% of voters backed preserving Zcash's bitcoin-style halvings over a more gradual new-coin issuance model. Halvings cut miner rewards in half at fixed intervals, removing supply on a known schedule.
