Tether Launches Open-Source Bitcoin Mining Operating System

Tether has open-sourced a new operating system for bitcoin mining, unveiling MiningOS (MOS) as part of a broader push to reduce the industry’s reliance on proprietary, vendor-controlled software.

The stablecoin issuer announced Monday that MOS, a modular and scalable operating system designed to manage, monitor, and automate bitcoin mining operations, is now available as open-source software under the Apache 2.0 license. 

The system was officially unveiled at the 2026 Plan ₿ Forum in San Salvador.

According to Tether, MOS is built to coordinate the complex mix of hardware, power systems, containers, and physical infrastructure that underpin modern bitcoin mining. 

Rather than relying on fragmented software stacks, the operating system treats every component of a mining site as a controllable “worker” within a single operational layer, providing operators with unified visibility across hashrate, energy usage, device health, and site-level infrastructure.

The company said MOS uses a self-hosted, peer-to-peer architecture based on Holepunch protocols, allowing miners to manage operations without relying on centralized services or third-party platforms. 

The system is designed to scale from small home installations running on lightweight hardware to industrial-grade deployments managing hundreds of thousands of machines across multiple locations.

“Mining OS is built to make Bitcoin mining infrastructure more open, modular, and accessible,” said Tether CEO Paolo Ardoino. “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.”

Tether’s Mining SDK announcement

Alongside MOS, Tether also announced the Mining SDK, the framework on which the operating system is built. The Mining SDK is expected to be finalized and released in collaboration with the open-source community in the coming months.

The toolkit is designed to allow developers to build mining software and internal tools without recreating device integrations or operational primitives from scratch, offering ready-made workers, APIs, and UI components.

Tether said the goal of open-sourcing its mining stack is to lower barriers to entry for new miners and remove the “black box” nature of many existing mining setups, where hardware and monitoring tools are tightly coupled to proprietary platforms.

The release places Tether alongside other crypto firms pushing open-source mining infrastructure, including Jack Dorsey’s Block, which has previously backed efforts to decentralize mining tooling and hardware access.

MOS marks another step in Tether’s expansion beyond its core stablecoin business. The company has increasingly positioned itself across mining, payments, and infrastructure, reporting more than $10 billion in net profit in 2025, driven largely by interest income on its reserves.
