Fortitude Mining Holdings, a digital asset mining company focused primarily on Zcash, has announced plans to go public through a merger with Nasdaq-listed healthcare technology firm HeartSciences in a deal that would create one of the few publicly traded companies centered on cryptocurrency mining outside of Bitcoin.
The companies revealed they have entered into a definitive all-stock merger agreement that is expected to close during the second half of 2026, subject to shareholder approval and other customary conditions. Following completion of the transaction, the combined company is expected to operate under the Fortitude brand and trade on the Nasdaq Capital Market under the proposed ticker symbol “TUDE,” pending exchange approval.
The deal represents a notable development for the Zcash ecosystem, which has historically received less institutional attention than larger proof-of-work networks such as Bitcoin. Fortitude, currently owned by Digital Currency Group (DCG), says it intends to position itself as a publicly traded “venture mining” company focused on identifying and scaling emerging proof-of-work opportunities.
Public Markets Gain a Rare Pure-Play Zcash Mining Exposure
Fortitude’s business differs from many publicly listed crypto mining companies, which are overwhelmingly focused on Bitcoin. The company has built its operations around Zcash, a privacy-focused cryptocurrency launched in 2016 that shares Bitcoin’s fixed 21 million coin supply model while incorporating optional privacy-preserving transaction technology.
According to the company, Fortitude began mining Zcash in 2019 and has scaled production to an annualized rate of approximately 157,000 ZEC, equivalent to roughly 366 ZEC per day as of May 31, 2026.
The company describes its model as vertically integrated, controlling infrastructure, power procurement, hardware deployment, and mining operations. It also owns and operates data center assets and long-term power agreements designed to lower production costs.

Fortitude’s leadership argues that this structure allows it to identify and capitalize on emerging proof-of-work opportunities before they become widely recognized by the market.
The company’s emphasis on Zcash reflects growing institutional interest in privacy-focused digital assets, although that segment of the cryptocurrency market remains relatively small compared to Bitcoin and Ethereum. Privacy coins have historically faced additional regulatory scrutiny in some jurisdictions due to concerns about transaction anonymity and compliance requirements.
DCG Maintains Dominant Ownership Position
One of the most significant aspects of the transaction is the ownership structure that will remain in place after the merger.
Fortitude’s sole shareholder, Digital Currency Group, is expected to own approximately 95% of the combined company on a fully diluted basis following completion of the deal. The structure effectively allows DCG to bring Fortitude to public markets while retaining overwhelming control of the business.
DCG founder and CEO Barry Silbert described Zcash as a compelling digital asset due to its combination of Bitcoin-style scarcity, proof-of-work security, and privacy features.
The merger also enables HeartSciences shareholders to maintain exposure to the combined company while allowing the healthcare business to continue pursuing development of its artificial intelligence-enabled electrocardiogram technology. Current HeartSciences CEO Andrew Simpson is expected to continue leading the healthcare division after the transaction closes.
Meanwhile, Fortitude CEO Andrea Childs is expected to lead the combined company.
Why the Deal Matters for Crypto Markets
The proposed transaction arrives amid renewed investor interest in publicly traded cryptocurrency companies, particularly those linked to mining, infrastructure, and treasury strategies.
While Bitcoin mining firms have become a recognized category on public markets, few publicly listed companies provide concentrated exposure to alternative proof-of-work networks. If completed, Fortitude could become one of the first Nasdaq-listed companies whose operations are primarily tied to Zcash mining and infrastructure.

The company also seeks to differentiate itself through what it calls a “venture mining” approach, which involves identifying promising proof-of-work ecosystems at relatively early stages and deploying capital, infrastructure, and operational expertise to build strategic positions.
However, investors should note that the transaction remains subject to regulatory approvals, Nasdaq acceptance of the proposed listing structure, and shareholder approval from HeartSciences. The merger has been announced but is not yet finalized.
Additionally, many of Fortitude’s projections and strategic objectives remain company claims rather than independently verified outcomes. The long-term success of the business will depend on cryptocurrency market conditions, mining economics, energy costs, regulatory developments, and the continued growth of the Zcash ecosystem.
A Growing Institutional Narrative Around Zcash
The announcement also reflects a broader trend in which some investors and crypto infrastructure companies are revisiting privacy-focused blockchain networks.
Recent developments across the Zcash ecosystem—including network upgrades, infrastructure expansion, wallet improvements, and growing institutional discussion around privacy-preserving financial technology—have contributed to renewed attention for the project.
While Bitcoin continues to dominate proof-of-work mining, Fortitude’s planned public debut suggests that some market participants see opportunities in alternative networks that offer distinct technological features beyond Bitcoin’s core functionality.
Whether that thesis ultimately succeeds will likely depend on the pace of adoption for privacy-enhancing blockchain technologies and the willingness of public market investors to embrace a company built around a less conventional segment of the cryptocurrency industry.
