Cypherpunk Adds Zcash Mining Fleet in $33.33M Winklevoss Deal, Names Kevin Zhang Head of Mining

4 min readPublished 19 Aug 2026

Cypherpunk Technologies, the Nasdaq-listed company trading as CYPH, says it has built the world’s largest Zcash mining fleet and put industry veteran Kevin Zhang in charge of running it. The announcement, made August 18, 2026, was covered separately by Crypto Briefing and Decrypt — and each outlet came away with a different half of the story.

Both outlets agree on the headline mechanics: Cypherpunk launched a unit called Cypherpunk Mining, funded through a $33.33 million equity-based transaction with Winklevoss Capital, the investment arm founded by Cameron and Tyler Winklevoss. The fleet is already live, running a US-based Equihash hashrate of 4.2 GSol/s, which the company says represents roughly 18% of the entire Zcash network, according to both Crypto Briefing and Decrypt.

What only one outlet has

Crypto Briefing is the only source for Zhang’s résumé: he posts under the handle @SinoCrypto and previously served as SVP of Mining Strategy at Foundry, one of Bitcoin’s largest mining pool operators, and as Head of Asia at Nakamoto Holdings. Crypto Briefing also reports that Cypherpunk was formerly Leap Therapeutics, a biotech company focused on cancer therapy, which rebranded to Cypherpunk Technologies in November 2025 while keeping the cancer pipeline running as a subsidiary. Since the rebrand, Crypto Briefing reports, the company has put $5 million into Zcash Open Development Labs, an ecosystem group supporting Zcash protocol development. Crypto Briefing also cites the company’s claim that its ZEC treasury was built at average prices between $200 and $300-plus per coin, and that Zcash mining is more profitable per megawatt than either Bitcoin mining or AI colocation.

Decrypt, by contrast, has the deal’s structure and the treasury math that Crypto Briefing does not mention. Decrypt reports that Cypherpunk financed the acquisition without cash, instead issuing a pre-funded warrant covering roughly 43.3 million shares priced at $0.77 apiece, to pay for new Z15 Pro mining machines and their hosting agreements. Decrypt also reports that Cypherpunk already ranks as the largest corporate holder of ZEC, with about 323,394 coins — roughly 1.92% of circulating supply — and that the company is aiming to reach 5%. With approximately 43,800 ZEC minted to miners each month, Decrypt reports the company’s argument that mining lets it acquire coins below market price, accelerating that target.

Only Decrypt carries direct comment from the Winklevoss side. Cameron Winklevoss posted on X after the announcement:

“Zcash hashrate has been concentrated in a small number of miners, pools, and ASIC makers—almost all of it outside the United States,” … “Cypherpunk is changing that. Our fleet is deployed across U.S. facilities, owned outright, with zero debt and power costs locked in low.”

Decrypt also reports that Chief Investment Officer Will McEvoy described mining as the next stage of the company’s privacy-focused strategy, with the ZEC produced intended to fund further growth, additional coin purchases, and privacy-technology investments.

Where the reporting agrees, and where it doesn’t

On the core facts — the launch date, the $33.33 million Winklevoss Capital deal, the 4.2 GSol/s hashrate figure, the 18% network-share claim, and Zhang’s appointment as Head of Mining following his time at Foundry — Crypto Briefing and Decrypt line up. Neither outlet disputes the other’s numbers where they overlap.

The disagreement is one of coverage, not conflict: Crypto Briefing has the personnel and corporate-history context (Zhang’s career, the biotech rebrand, the ZODL investment), while Decrypt has the deal architecture and treasury figures (the warrant structure, the 323,394-ZEC holding, the 5% target). Read alone, either article gives an incomplete picture of how the deal was actually financed or why Cypherpunk exists in its current form.

One detail from Decrypt stands apart and is not addressed by Crypto Briefing at all: Decrypt reports that Cypherpunk’s stock plunged nearly 40% at one point amid an episode it links to “Zcash privacy” — but the available text of Decrypt’s report cuts off before describing what actually happened, so the nature of that episode and how it was resolved are not established by the evidence. Decrypt also notes that ZEC rallied even as Bitcoin slipped in late 2025, and that Zcash creator Zooko Wilcox joined the effort at the tail end of that year — context that gives the mining launch a backdrop of volatility neither outlet fully unpacks.

What remains unverified

Cypherpunk’s central claims — that it operates the world’s largest Zcash mining fleet and controls roughly 18% of the network’s hashrate — come from the company’s own announcement and are relayed, not independently confirmed, by either Crypto Briefing or Decrypt. Neither outlet cites third-party network data, a mining pool disclosure, or an analyst assessment to test the figure. The same applies to Cypherpunk’s assertion that Zcash mining beats Bitcoin mining and AI colocation on a per-megawatt basis; that comparison is the company’s framing, repeated by Crypto Briefing, not an outside analysis.

Also unresolved: what exactly caused the stock’s earlier roughly 40% decline, which Decrypt links to a Zcash-privacy-related episode without specifying further, and the timeline for Cypherpunk reaching its stated goal of holding 5% of circulating ZEC supply.

Why it matters

A Nasdaq-listed company that started as a cancer-therapeutics biotech is now running what it calls the largest Zcash mining operation in the world, backed by one of crypto’s most recognizable investor names. If the hashrate and treasury figures hold up under scrutiny, it gives public-market investors a rare direct route to Zcash mining exposure. For now, that scrutiny hasn’t happened in the reporting available: both outlets are working from the company’s own disclosure, and the story of how the deal was actually structured — the warrant, the share count, the treasury targets — only fully emerges when their two accounts are read together.
