February 2, 2026 – Tether, the largest digital asset company, today announced the open sourcing of its Mining OS (MOS), an operating system designed to manage, monitor, and automate Bitcoin mining operations at scale. MOS provides end-to-end visibility across the mine site, integrating hardware, energy, infrastructure, and operational data into a single integrated system. The open sourcing of MOS was officially announced at the 2026 Plan ₿ Forum in San Salvador.
Bitcoin mining operations rely on a complex combination of machines, power systems, containers, and physical infrastructure. MOS is built to coordinate these moving parts by treating all components as controllable workers within a single operational layer. The system monitors not only hashrate, but also energy usage, device health, and site-level infrastructure, allowing operators to manage their mining environments holistically rather than through a fragmented software stack.
MOS is designed to be scalable, resilient, and modular with a peer-to-peer architecture that supports deployment from small facilities to large industrial sites. This operating system can run on lightweight hardware for small-scale operations or scale to monitor and manage hundreds of thousands of mining devices across site-wide deployments.
Alongside MOS, Tether also announced the Mining SDK, the framework on which MOS is built. This will be completed 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 having to recreate device integration or operation primitives from scratch. It includes ready-to-use workers, a simple API, and a UI development kit to quickly build and deploy dashboards and internal tools.
“MOS, the mining OS, is built to make Bitcoin mining infrastructure more open, modular, and accessible. Whether you are a small operation running a few machines or a full-scale industrial site, the same operating system can scale without relying on centrally managed third-party software,” he said. Paolo Ardoino, CEO of Tether. “Open sourcing our mining software stack will allow new mining companies to enter the ecosystem, customize their operations, and compete on a more level playing field, ultimately making the Bitcoin network more resilient.”
While MOS is available as a production-ready operating system for mining operators, the Mining SDK is presented as open source software to foster collaboration and ecosystem development.
