Tether, best known as the issuer of the USDT stablecoin, has released an open-source operating system designed for Bitcoin mining, marking another step in the company’s expansion beyond stablecoins and into core crypto infrastructure.
Announced on Monday, the new platform is called MiningOS, or MOS. It is built to help miners manage, monitor, and automate Bitcoin mining operations at different scales, from individual machines running at home to large, industrial mining facilities spread across multiple locations.
By making the software open source, Tether is positioning MOS as an alternative to proprietary mining management systems that often tie operators to specific vendors and closed platforms.
An open alternative to proprietary mining software
Tether first signaled its interest in open-source mining software last year, arguing that Bitcoin mining should not require expensive, closed-source tools that can limit competition. The company’s move aligns with a broader push within the industry to make mining infrastructure more transparent and accessible. Other players, including Block, the payments firm led by Jack Dorsey, have publicly supported similar efforts.
According to Tether, MOS is designed around a modular, peer-to-peer architecture. This approach allows miners to operate without relying on centralized services, which can become single points of failure or control.
Instead of juggling multiple tools for hardware management, energy monitoring, and performance tracking, MOS aims to bring these functions together into a single operational layer. The system is built to coordinate mining hardware, energy usage, device health, and site-level infrastructure, giving operators a clearer view of their entire setup.
Built to scale and remain flexible
Paolo Ardoino, Tether’s CEO, said the goal behind MOS is to make Bitcoin mining infrastructure “more open, modular, and accessible.” He emphasized that the operating system can scale from a single mining rig to industrial-grade sites operating across different regions, without forcing miners into third-party platforms.
Tether says MOS is hardware-agnostic, meaning it is not restricted to specific manufacturers or equipment. This flexibility could appeal to miners looking to diversify hardware or avoid long-term dependencies on certain vendors.
The software has been released under the Apache 2.0 open-source license, a widely used framework that allows developers to use, modify, and distribute the code with relatively few restrictions. Alongside MOS, Tether also announced a Mining Software Development Kit (SDK), which serves as the underlying framework for the operating system.
The company plans to release and further develop the SDK in collaboration with the open-source community in the coming months, suggesting that external developers will play a role in shaping the platform’s future.
Part of a broader expansion beyond USDT
The launch of MOS fits into a wider strategy as Tether continues to diversify its business. While USDT remains the world’s most widely used stablecoin, the company has been steadily expanding into mining, payments, and infrastructure-related projects.
Tether reported more than $10 billion in net profit in 2025, driven largely by interest income earned on its reserves. That financial strength has given the company room to invest in new products and areas of the crypto ecosystem.
In recent months, Tether has also moved into tokenized commodities, including gold-backed digital assets, and introduced a U.S.-focused stablecoin known as USAT. At the same time, Ardoino has publicly downplayed Tether’s direct involvement in ongoing debates around yield-bearing stablecoins in the United States.
What this means for Bitcoin mining
By releasing MOS as open-source software, Tether is adding another option for miners who want more control over their operations and fewer dependencies on closed systems. Whether MOS gains widespread adoption will depend on how well it performs in real-world environments and how actively the developer community engages with the project.
Still, the move highlights a growing interest among large crypto firms in supporting open infrastructure, particularly in areas as critical as Bitcoin mining.
