Tether Open-Sources Bitcoin Mining Operating System MOS at Plan ₿ Forum

2 February, 2026—Tether, a leading company in the digital assets industry, has announced the open-sourcing of Mining OS (MOS), an operating system designed to manage, monitor, and automate Bitcoin mining operations at scale. The announcement was made at the 2026 Plan ₿ Forum in San Salvador.

MOS provides end-to-end visibility across mining sites, integrating hardware, energy, infrastructure, and operational data into a single unified system. This development aims to streamline Bitcoin mining operations, which typically rely on a complex mix of machines, power systems, containers, and physical infrastructure.

The system is designed to coordinate these components by treating each as a controllable worker within one operational layer. It monitors not only hashrate but also energy usage, device health, and site-level infrastructure. This holistic approach allows operators to manage mining environments more effectively, avoiding fragmented software stacks.

Scalable and Modular Design

MOS is built to be scalable, resilient, and modular, featuring a peer-to-peer architecture that supports deployments ranging from small installations to large industrial sites. It can run on lightweight hardware for small-scale operations or scale to manage hundreds of thousands of mining devices across full-site deployments.

Alongside MOS, Tether introduced the Mining SDK, the framework on which MOS is built. 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 for building and deploying dashboards and internal tools quickly.

Open-Source Initiative

Paolo Ardoino, CEO of Tether, stated, “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.”

By open-sourcing the mining software stack, Tether aims to enable new mining companies to enter the ecosystem, customize their operations, and compete on more equal footing, which could strengthen 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. More information can be found here.

Why This Matters: Impact, Industry Trends & Expert Insights

Tether has open-sourced its Mining OS (MOS) and Mining SDK, aiming to streamline and democratize Bitcoin mining operations by providing a scalable, modular, and open-source platform.

Recent industry reports indicate a shift towards enhanced efficiency and cloud integration in open-source Bitcoin mining software. This aligns with Tether’s initiative to open-source MOS, which aims to provide transparency and accessibility in Bitcoin mining operations.

As per insights from a report by Investing.com, modular mining systems enhance Bitcoin network resilience by enabling scalable operations and reducing downtime. This supports Tether’s goal of fostering a more resilient and accessible Bitcoin mining ecosystem through its open-source platform.
