Stablecoin giant Tether has officially released its open-source Bitcoin mining operating system, MiningOS (MOS), marking a significant expansion of its activities beyond stablecoins. The announcement was made via a post on X on Monday, with the company positioning the software as a modular, scalable solution designed to simplify operations and promote decentralization within the mining sector.
The core of Tether's announcement is the belief that the mining industry has been constrained by proprietary, closed systems. "The mining industry has long been limited by closed systems and proprietary tools. MiningOS changes that — introducing transparency, openness, and collaboration into the core of Bitcoin infrastructure," Tether stated on its dedicated MOS website, adding the tagline: "No black boxes. No lock-in. No Limits."
Technically, MiningOS is a self-hosted mining architecture that communicates via an integrated peer-to-peer (P2P) network, built on Holepunch P2P protocols. This design eliminates reliance on centralized services or third-party dependencies. The software has been released under the Apache 2.0 open-source license, making it free to use, modify, and build upon.
The platform includes a management interface that allows miners to adjust settings based on their scale and output requirements, supporting monitoring of hardware performance, energy usage, and site operations. Tether CEO Paolo Ardoino emphasized its flexibility, calling it a "complete operational platform that can scale from a home setup to industrial grade site, even across multiple geographies."
Tether initially revealed plans for this open-source mining OS in June 2025, stressing the need for new miners to "be able to enter the game and compete" without depending on expensive third-party vendors. The release places Tether alongside other industry players like Jack Dorsey's Block, which has also developed open-source mining software. However, Tether distinguishes MiningOS by highlighting its compatibility with a wide range of mining infrastructure, unlike some solutions designed for specific hardware.
This move is part of Tether's broader strategic pivot into Bitcoin and adjacent technologies. Throughout 2025, the company made a series of investments spanning tokenization, artificial intelligence, and decentralized finance (DeFi), while also significantly increasing its holdings of both gold and Bitcoin. Although Tether scaled back some of its own physical mining operations in late 2025 due to rising energy costs, the MiningOS initiative represents a software-focused contribution aimed at strengthening the foundational infrastructure of the Bitcoin network.
