A single Nasdaq company now runs about 18% of all Zcash hashrate. Cypherpunk Technologies switched on 4.2 GSol/s of mining power this week, funded by a $33.33 million equity deal with Winklevoss Capital, and called it the largest ZEC mining fleet in the world. The pitch was decentralization, though the shape of the deal points the other way.
Cameron Winklevoss framed the move as a fix. Zcash hashrate, he said, had been "concentrated in a small number of miners, pools, and ASIC makers, almost all of it outside the United States." Cypherpunk's answer to that concentration is a US operation that, on day one, holds a bigger slice of the network than most of the miners it was meant to balance out.
18% of the hashrate, 1.92% of the coins, and a goal of 5%
The mining fleet is only half of it. Cypherpunk already holds 323,394 ZEC, roughly 1.92% of circulating supply and worth around $182 million with ZEC trading near $563. The company has said it wants 5% of the supply. So one firm is now the network's largest miner and a large holder that is still buying.
| What Cypherpunk controls | Figure | Share of the network |
|---|---|---|
| Mining hashrate | 4.2 GSol/s | about 18% |
| ZEC treasury | 323,394 ZEC | 1.92% of circulating supply |
| Stated supply goal | 5% of ZEC | still accumulating |
| Equity funding | $33.33 million | Winklevoss Capital |
That vertical grip matters more on a small chain than a large one. Zcash pays miners around 1,440 ZEC a day. Eighteen percent of that flow is a steady stream of fresh coins landing in the treasury of a company that is also trying to corner the float. news.bitcoin.com put it plainly: a single corporate operator can become influential on a relatively small proof-of-work network.
Concentration on this scale is not new to crypto. On Solana, one provider was recently found holding 27% of all staked SOL, above the chain's own safety cap. You can read that case here. What sets Cypherpunk apart is that its concentration spans two layers at once, mining and supply, and it is being sold as the cure.
Governance was already the pressure point
Zcash spent the summer arguing about issuance, and its NU7 vote, which needed a million ZEC to pass, cleared that bar earlier this month and changed how the chain handles its funding. The privacy side has its own open question: the shielded pool holds 3.5 million ZEC that have gone quiet, sealed off from easy movement. Into that mix walks a Nasdaq-listed treasury with a mining rig and a goal of owning a twentieth of everything.
Kevin Zhang, hired to run the mining arm, compared the opening to bitcoin mining in 2016. That comparison cuts both ways. Early bitcoin mining was cheap and open too, and it ended with a handful of pools deciding a lot. For now, Cypherpunk's stock trades close to ZEC. The number to watch next is whether its Zcash hashrate share climbs past 18%.
