Stablecoin issuer Tether has released MiningOS (MOS), an open-source Bitcoin mining operating system designed to simplify and scale mining while encouraging decentralization. Announced on X, Tether describes MOS as a modular, scalable stack suitable for hobbyists through to large institutional sites, with a self-hosted architecture that communicates over an integrated peer-to-peer network.
Tether says MOS brings transparency and interoperability to an industry long dominated by closed systems and proprietary tools, summing its approach as “No black boxes. No lock-in. No Limits.” The platform includes a user-friendly interface to adjust settings by scale and output, and CEO Paolo Ardoino called it “a complete operational platform that can scale from a home setup to industrial grade site, even across multiple geographies.”
Built on Holepunch P2P protocols, MiningOS is open source under the Apache 2.0 License — free to use, modify, and extend — and emphasizes no centralized services, no backdoors, and no third-party dependencies. Tether positions MOS as broadly compatible with a wide range of mining infrastructure, in contrast to other open-source efforts like Block’s stack, which is optimized for that firm’s specific hardware.
Tether first announced plans for an open-source mining OS in June, noting the importance of lowering barriers for new miners so they can compete without relying on expensive third-party vendors. The MOS launch forms part of Tether’s broader expansion beyond stablecoins: in 2025 the company made several investments across tokenization, artificial intelligence, and decentralized finance, and increased its holdings of gold and Bitcoin.
