TL;DR - Foundry Digital, operator of the world's largest Bitcoin mining pool (32% of global hashrate), is launching an institutional-grade Zcash mining pool in April 2026. The move signals that privacy coins have crossed a regulatory comfort threshold for serious U.S.-based infrastructure operators.
The Institutional Signal Behind the Hashrate
Foundry USA Pool mined roughly 4,150 BTC last month - about $290 million worth. It commands nearly a third of Bitcoin's entire network processing power. When an operator of that scale commits dedicated infrastructure to a new blockchain, it's not a side bet. It's a thesis.
The thesis: privacy coins are now institutional-grade. CEO Mike Colyer framed it explicitly. Zcash has crossed from ideological experiment into something compliance teams can underwrite. A U.S.-based, auditable, regulated mining pool for a privacy coin would have been unthinkable two years ago.
Why Zcash, Why Now
The economic case built itself over six months. Zcash's network hashrate surged 70% since September, climbing from 8.1 to 13.8 GSol/s. ZEC rallied over 670% in twelve months to trade around $215. But Foundry isn't chasing price action. They're filling a structural gap.
The current Zcash mining landscape lacks institutional-grade infrastructure. ViaBTC leads with roughly 31.7% of hashrate. F2Pool holds about 15.8%. Neither operates with the compliance framework, auditable payout methodology, or round-the-clock institutional support that public companies and regulated entities require.
Foundry's pool will have no minimum hashrate threshold and competitive fee rates. The infrastructure mirrors what made Foundry USA Pool dominant in Bitcoin - compliance-first design built for operators who answer to shareholders and regulators, not just block rewards.
Different Chains, Different Hardware
One critical technical detail: Bitcoin and Zcash use fundamentally different proof-of-work algorithms. Bitcoin runs on SHA-256. Zcash runs on Equihash. The mining hardware is not interchangeable.
This means Foundry isn't redirecting idle Bitcoin ASICs. They're deploying entirely new, dedicated infrastructure. That's a capital commitment that goes beyond opportunistic diversification.
| Bitcoin Mining | Zcash Mining | |
|---|---|---|
| Algorithm | SHA-256 | Equihash |
| Top Pool | Foundry USA (~32%) | ViaBTC (~31.7%) |
| Hardware | SHA-256 ASICs | Equihash ASICs/GPUs |
| Institutional Pool | Foundry USA (est. 2020) | Foundry ZEC (April 2026) |
| Network Hashrate Trend | Stable/growing | +70% since Sept |
The Regulatory Comfort Threshold
Foundry's move sits at the intersection of two trends. First, the broader regulatory thaw. The SEC and CFTC just signed a landmark MOU for unified crypto oversight. Kraken secured a Federal Reserve master account. ZeroHash obtained an OCC national trust bank charter. The compliance infrastructure is being built at every layer.
Second, Foundry's parent company is Digital Currency Group - the same entity behind Grayscale, CoinDesk, and Genesis. DCG doesn't deploy subsidiary capital into markets where regulatory risk remains existential. The Zcash pool is a tell. It means DCG's compliance and legal teams have concluded that privacy coin mining in the U.S. is defensible.
What to Watch Next
Three things determine whether this becomes a market-reshaping event or a footnote. First: how much hashrate migrates to Foundry's pool after April launch. If they capture 30%+ quickly, it validates institutional demand. Second: U.S. regulatory response. Privacy coin mining by a major U.S. operator will get attention from FinCEN and Treasury. Third: whether the hashrate acceleration continues. The 70% surge since September could be early innings - or it could be a local peak.
The pool launches in April 2026. Interested miners can contact zcash@foundrydigital.com.
NOT INVESTMENT ADVICE. This article discusses cryptocurrency mining operations and digital asset markets. Nothing in this piece constitutes a recommendation to mine, purchase, or hold Zcash, Bitcoin, or any other digital asset. Mining profitability depends on hardware costs, electricity rates, network difficulty, and asset prices - all of which fluctuate. Do your own research.
