2 February, 2026 – Tether, the largest company in the digital assets industry, today announced the open-sourcing of Mining OS (MOS), an operating system designed to manage, monitor, and automate Bitcoin mining operations at scale. MOS provides end-to-end visibility across mining sites, bringing hardware, energy, infrastructure, and operational data into a single unified system. The open-sourcing of MOS was officially unveiled at the 2026 Plan ₿ Forum in San Salvador.
Bitcoin mining operations rely on a complex mix of machines, power systems, containers, and physical infrastructure. MOS is built to coordinate these moving parts by treating every component as a controllable worker within one operational layer. The system monitors not only hashrate, but also energy usage, device health, and site-level infrastructure, enabling operators to manage mining environments holistically rather than through fragmented software stacks.
MOS is designed to be scalable, resilient, and modular, with a peer-to-peer architecture that supports deployments ranging from small installations to large industrial sites. The operating system can run on lightweight hardware for small-scale operations or scale to monitor and manage hundreds of thousands of mining devices across full-site deployments.
Alongside MOS, Tether also announced Mining SDK, the framework on which MOS is built, that will be finalized and released in collaboration with the open-source community in the coming months. The Mining SDK is a modular toolkit that allows developers to build mining software without recreating device integrations or operational primitives from scratch. It includes ready-to-use workers, simple APIs, and a UI development kit that enables dashboards and internal tools to be built and deployed quickly.
“Mining OS, MOS, is built to make Bitcoin mining infrastructure more open, modular, and accessible. Whether it’s a small operator running a handful of machines or a full-scale industrial site, the same operating system can scale without reliance on centralized, third-party software,” said Paolo Ardoino, CEO of Tether. “By open-sourcing our mining software stack, we’re enabling new mining companies to enter the ecosystem, customize their operations, and compete on more equal footing, which ultimately strengthens the resilience of the Bitcoin network.”
MOS is available as a production-ready operating system for mining operators, while the Mining SDK is announced as open-source software to encourage collaboration and ecosystem development.
