Zcash holders vote on its money supply as Wall Street starts buying

For most of its decade on the market, Zcash was the privacy coin that few people used for privacy. That has changed underneath the price. More than half of Zcash transactions are now shielded, up from about a fifth a year ago, zecstats data show, and the coins held in those private pools get a direct say on Monday in how the network issues its last 4.07 million ZEC.

The price is doing the shouting. ZEC was near $1,170 late Friday, up 139% in 30 days and nearly 25 times its level of a year ago, according to CoinGecko, which ranks it the 10th-largest cryptocurrency at about $19.9 billion. Grayscale’s spot Zcash ETF, which began trading on Aug. 25, explains the speed of that move. The ballot that closes at 19:00 UTC on Sept. 14 reaches further, into how fast new coins arrive for the next four years and beyond.

Put the two together and the rally reads less like a meme and more like a supply story: a new class of buyer arriving through a stock-exchange wrapper, just as existing holders vote on whether to keep Bitcoin-style halvings at all.

1. 01The move–ZEC is up 139% in 30 days to about $1,170, the 10th-largest cryptocurrency at roughly $19.9 billion.
2. 02The demand–Grayscale’s Zcash ETF passed $500 million in assets two weeks after launch, but $100 million of that came from a DCG affiliate; outside inflows were more than $70 million.
3. 03The supply–Block rewards add about 1,514 ZEC a day, so two weeks of outside ETF buying absorbed five to eight weeks of new coins.
4. 04The vote–Monday’s ballot covers replacing halvings with smooth issuance, when removed coins are reissued, retiring the Sprout pool, 25-second blocks and NU7’s timing.
5. 05The risk–ZEC trades at 3.75 times its realized price and fell 72% after last November’s peak, and EU exchanges must drop privacy coins from July 2027.

How a privacy coin picked up an ETF bid

The run has a clear starting line, and it came before the ETF. In late May, researcher Taylor Hornby of Shielded Labs found a flaw in the proof circuit of Orchard, Zcash’s main shielded pool since 2022, that could have let an attacker mint counterfeit ZEC without leaving a trace. On July 28 the network activated Ironwood, sealing about 3.66 million ZEC inside Orchard behind a turnstile that caps withdrawals at what was verifiably deposited, CoinDesk reported. ZEC closed that day at $476.

A scare like that usually drains a privacy pool. This one did not. Holders walked coins across the turnstile into Ironwood instead of out of the system, and in the third week of August the market started to reprice the chain. ZEC went from $486 on Aug. 17 to $853 on Aug. 24, a 75% gain in seven days, before a single ETF share had traded.

The fund, ZCSH, started trading on NYSE Arca on Aug. 25 as the first exchange-traded product offering spot ZEC exposure. Two weeks later its assets had passed $500 million. The fund’s Sept. 8 filing adds context the headline figure skips: $100 million of it came from DCG International Investments, described as an affiliate of both the fund and its sponsor, part of the Digital Currency Group family that owns Grayscale. Outside inflows were more than $70 million.

ZEC broke $1,000 on Sept. 4 for the first time outside the chaotic first days of trading in 2016, according to The Block, and closed at a cycle high of $1,244 on Sept. 10. It has gained about 42% since the ETF’s first day.

What the ETF absorbs, and what the chain adds

Zcash mints 1.5625 ZEC every 75-second block, the rate set by its November 2024 halving. Coinbase rewards come to about 1,514 ZEC a day on zecstats’ count, an issuance rate near 3.3% a year.

Against that, the ETF’s outside money is large. At the $830 to $1,244 range ZEC traded in over the fund’s first two weeks, $70 million buys roughly 56,000 to 84,000 coins. That is five to eight weeks of new supply taken off the market in two. The ratio explains the speed of the move better than sentiment does. It also explains why the move needs the flows to continue, because 1,514 fresh coins arrive every day whether the ETF buys or not.

Miners have followed the price rather than led it. Zcash’s hashrate now runs at 27.5 GSol/s, up 265% over the past year on zecstats’ numbers, and The Block counted the network’s solrate climbing from roughly 25 GSol/s in late August to briefly above 30 GSol/s as ZEC broke $1,000. None of that creates extra coins. The protocol issues its 1,514 a day whether one machine is running or a million are, so the effect of a hashrate surge is on the cost of producing each coin, and on how quickly the miners who produce them need to sell.

One of those miners is also a large holder. Cypherpunk Technologies bought Winklevoss Capital’s Zcash mining fleet for $33.33 million in an equity-based deal in August, a fleet it put at about 18% of network hashrate, and says it holds 323,394 ZEC, roughly 1.9% of circulating supply, with a stated target of 5%, Cointelegraph reported. That is a second bid competing with the ETF for the same thin float, and one that does not have to sell into strength.

The supply side also has less room than it used to. Of the 21 million ZEC that will ever exist, 16.93 million, or 80.6%, have already been issued. The remaining 4.07 million are what Monday’s vote is about.

Monday’s ballot is about the last 4 million coins

Two polls close together. The Zcash Foundation’s ZCAP advisory panel poll runs until 19:00 UTC on Monday, Sept. 14, and asks five questions: whether to smooth issuance or keep halvings, when coins removed from circulation start being reissued (as soon as possible, February 2027 or February 2031), when to retire the old Sprout pool, whether to shorten block times, and whether NU7 should ship without its unfinished features or wait for them.

The coin-weighted poll is the newer experiment. On a purpose-built vote chain from Valar Group, each Ironwood-shielded ZEC at the snapshot height counts as one vote, according to the design posted to the Zcash forum, with transparent holders handled through the existing process. A 1 million ZEC participation line separates a representative result from a sample. Ballots are encrypted and tallied through threshold decryption, so individual votes stay private while the totals do not.

That line decides how much Monday’s outcome binds. A million ZEC is about 5.9% of all coins in circulation and roughly a quarter of everything sitting in Ironwood, which makes it a demanding bar for a pool built to keep holdings quiet. Clear it and the result reads as an instruction from coinholders that developers can point to. Miss it and NU7’s final scope stays an engineering judgment informed by a sample, with the same five questions unresolved.

Smoothing is where the economics change. Under the draft ZIP 234 formula, each block pays a fixed fraction, 0.0000004126, of the coins not yet issued. With 4.07 million ZEC left, that works out to about 1.68 ZEC a block at the current 75-second pace, roughly 7.5% more than the 1.5625 ZEC paid now. In exchange, the next halving, due around late 2028, disappears, and so does the four-year supply shock that halving-driven assets tend to trade around, the pattern TECHi traced in its Bitcoin halving analysis.

The reissuance question matters for the same reason. ZIP 234 feeds burned or voluntarily removed coins back into the reserve, so later blocks pay them out again. Voting for “as soon as possible” starts that loop sooner, while February 2031 pushes it out by more than four years. Faster blocks, proposed at 25 seconds, would spread the same issuance across three times as many blocks without touching the 21 million cap.

The usage underneath the price

The figure that says the most about ZEC is not its price. Shielded pools hold 28.9% of all ZEC, about 4.89 million coins, up from 23.3% a year ago and 7.6% five years ago. Shielded transactions make up 52% of the roughly 12,044 recorded each day, against 21% a year ago, while total daily transactions are up 364% on the year. Ironwood alone holds 3.94 million ZEC, with about 420,000 still waiting in Orchard to cross.

That is the part an ETF cannot buy. A ZCSH share gives price exposure and shields nothing, much as Grayscale’s TAO fund cannot stake the tokens it holds. Two groups of buyers are now pulling on the same fixed pool of coins for different reasons, one for exposure and one for use, and only one of them shows up on Monday’s ballot.

Where the rally is stretched

By TECHi’s count on CoinGecko daily closes, ZEC sits 73% above its 50-day average of about $679 and 151% above its 200-day average near $468. The on-chain picture agrees. Zecstats puts the realized price, the average price at which coins last crossed a pool boundary, at $313, and spot trades at 3.75 times that, so the typical holder is sitting on a large gain.

ZEC has been here recently. It peaked at $697 on Nov. 17 last year and fell 72% to $197 by March 8. The current run is six times that low and already 69% above the November high, and it trades like a much larger asset: over the past week, daily volume averaged about 6.7% of ZEC’s market value.

The regulatory clock runs the other way. Under the EU’s Anti-Money Laundering Regulation, exchanges and custodians licensed in the bloc will be barred from handling anonymity-enhancing coins such as ZEC from July 2027, Cointelegraph reported. Self-custody and peer-to-peer transfers fall outside the rule. European exchange liquidity does not.

The longer arc runs through Tachyon

Past NU7, Zcash’s next large project is Tachyon, a new shielded pool led by co-founder Sean Bowe that uses proof-carrying data to aggregate transactions and prune the state validators have to keep. Zcash says the design accommodates full post-quantum privacy. That puts ZEC on the other side of the question TECHi raised about Bitcoin this week, where the quantum-resistance proposal is still a draft while estimates of the cost of an attack keep falling, and while the hardware race tracked in TECHi’s quantum computing stocks guide keeps moving.

Monday settles the schedule, not the price

Results should follow once polling closes at 19:00 UTC. A representative vote for smoothing would move ZEC off the halving script it has followed since launch, trading a supply catalyst in 2028 for a slow, predictable decline in issuance. A vote to keep halvings preserves the four-year pattern. Either way, the ETF keeps doing what it has done since Aug. 25: adding a buyer that wants exposure, not privacy, to a coin whose holders increasingly want both.

The durable signal is not Monday’s headline. It is whether ETF flows keep outrunning 1,514 new coins a day, and whether the shielded share keeps climbing past 28.9% once the vote is over. For how a position this volatile fits next to larger holdings, TECHi’s crypto portfolio framework is the place to start.
