Who Is Zooko Wilcox, the Zcash Founder Whose Coin Closed at $1,628

Zooko Wilcox is the Zcash founder who ran the Electric Coin Company from 2015 to December 2023, and ZEC closed at $1,628.33 on Phemex on 22 September 2026. He's Chief Product Officer at Shielded Labs, a Swiss Zcash support group, and a strategic advisor to Nasdaq-listed Cypherpunk Technologies.

The precedent is a founder who stepped out of the chief executive's chair years before his coin's highest close in our record. He handed that company to Josh Swihart on 18 December 2023. Ten days later, ZEC's first bar in our 1,000-day Phemex record closed at $31.95. The 22 September close is the highest in that record, 46.60% above the 15 September close of $1,110.71.

Zooko Wilcox at a Glance

Who Is Zooko Wilcox and What Does He Do at Shielded Labs?

Zooko Wilcox is listed as Chief Product Officer on the Shielded Labs team page, which we loaded on 23 September 2026. Shielded Labs describes itself as an independent, donation-funded Zcash support organization based in Switzerland. Its own site says it's the first group in the Zcash ecosystem that has never received direct or indirect funding from the Development Fund or block rewards. Its stated mission is to build "unstoppable private money" through projects aimed at the sustainability and security of the Zcash network.

That funding line matters if you follow how Zcash pays for its own development, because a donor-funded group answers to its donors. The team page listed nine people on 23 September 2026, and the Cypherpunk release of 9 December 2025 already called him "current Chief Product Officer of Shielded Labs."

For the coin itself, our guide to what Zcash is and how ZEC works covers the coin's privacy design and its 21 million supply cap.

How the Zcash Founder Built ECC and Handed It Over

The Electric Coin Company formed in 2015, when it still went by the name the Zcash Company, and Zooko ran it from day one. ECC's board wrote on 18 December 2023 that "Under his leadership, ECC launched Zcash in 2016." The same post claims ECC delivered the first real-world application of zero-knowledge proofs, which let one party prove a statement is true without revealing anything else about it. It also lists the Sapling upgrade and the Halo proving system among ECC's highlights. Sapling, in the board's telling, made shielded transactions possible from a mobile wallet for the first time. Halo is described as a proving system that allows recursion without a trusted setup, and the post says it made trustless private payments on phones possible.

That post is also the handover notice. Josh Swihart, who had been ECC's senior vice president of growth, returned as chief executive. The board gave him responsibility for "all strategic and tactical decisions." Zooko stayed on as a director of the Bootstrap Project, ECC's parent, and the board said he would first take some time off.

The board seat is a fact as at 18 December 2023 only, and we found no primary that dates it past that post. What happened at ECC after the handover is covered in our profile of his successor Josh Swihart.

The Cryptography Behind Zooko Wilcox-O'Hearn

The BLAKE2 hash function's own site lists him as Zooko Wilcox-O'Hearn, the longer form of his name, among its four designers. The page introduces him as "one of the designers of the Tahoe-LAFS secure distributed storage system," a file store that uses fast hashing to check large amounts of data.

BLAKE2 grew out of BLAKE, a finalist in the SHA-3 competition, and its site says it hashes faster than MD5 while staying at least as secure as SHA-3. Its successor went further. The official BLAKE3 repository lists Zooko among its four designers alongside Jack O'Connor, Samuel Neves and Jean-Philippe Aumasson. The same page states that the Electric Coin Company sponsored the work.

One of his earliest ideas is a short essay on names that are decentralized, secure and human-meaningful, first archived in a version dated 12 October 2001. He revised it under its current title in a version dated 22 September 2003, and that title ends with the verdict "Choose Two." You can have any two of those properties in one naming system and never all three. The essay drew enough citations that he added a note in January 2006 pointing readers to newer work. That note still called the page important "for historical reasons." We read both versions through archive captures from October 2001 and December 2011, because the zooko.com domain sends visitors to a for-sale page.

The math that later carried Zcash's private payments is a different family of cryptography, and our explainer on how a zero-knowledge proof works covers it from the ground up.

What Zooko Wilcox Does for Cypherpunk Technologies

On 9 December 2025, Cypherpunk Technologies announced that Zooko had joined as a strategic advisor in a PR Newswire release. The company, formerly Leap Therapeutics, trades on Nasdaq as CYPH and runs a treasury strategy built on buying ZEC. The same release says the company still develops cancer therapies alongside that treasury, and it puts the private placement behind the switch at $58.88 million.

His quote in that release calls user-controlled privacy "a fundamental building block of a healthy and stable society." If you follow the stock, our page on Cypherpunk's Zcash holdings lays out what the company holds and who else sits on its advisory bench.

What the Zcash Price Record Shows on Phemex

ZECUSDT closed at $1,628.33 on 22 September 2026, up 10.72% from the 21 September close of $1,470.61. The previous highest close in the record was $1,558.90 on 18 September 2026, so the anchor bar beat it by 4.45%. Turnover on the bar came to $6,857,912. The record runs 1,000 daily bars from 28 December 2023, while the contract itself listed in December 2022. That makes $1,628.33 the highest Zcash price in the bars we hold, and never an all-time high.

Its lowest close in the same record was $18.26 on 5 July 2024.

The dates line up with his roles without explaining the move. ZEC closed at $404.93 on 8 December 2025, the last full bar before the Cypherpunk release, and the 22 September close sits 302.1% above it. We found no primary source that ties any part of that rise to him, and none is claimed here.

If you want exposure to that move, ZEC futures are the route, since the ZECUSDT contract is listed on Phemex with leverage of up to 50x. The founder has spent almost three years outside the chief executive's chair, and the six highest closes in the record all landed in September 2026.
