Key Highlights Tether open-sources its Mining OS at the Plan ₿ Forum, pushing Bitcoin mining toward open and decentralized infrastructure. MOS and the upcoming Mining SDK unify mining hardware, energy, and the data while enabling faster custom tool development. Open-source mining software shifts competition from access to efficiency, strengthening Bitcoin’s global mining ecosystem. Tether, the issuer of the USDT stablecoin, has open-sourced its Bitcoin Mining Operating System (MOS), in a push toward more decentralized Bitcoin mining. The company announced the move on February 2, 2026, making the software publicly available to the mining community. This update was announced at the 2026 Plan ₿ Forum in San Salvador, highlighting Tether’s expanding focus on Bitcoin infrastructure development. The announcement also marks a strategic pivot for the $120 billion plus company, aiming to break the “black box” of proprietary software that has long dominated industrial-scale mining operations. A unified “nervous system” for miners Current mining operations often resemble a patchwork of disconnected software: one for hashrate monitoring, another for electrical transformers, and a third for cooling systems. MOS seeks to replace this with a single operational layer. It’s a special computer operating system for Bitcoin mining, designed specifically to run and manage mining hardware and operations. MOS provides end-to-end visibility across mining sites—covering: Mining hardware performance Energy consumption and efficiency Device health and failures Infrastructure and site-level operations Tether ❤️ Bitcoin Tether Mining OS is now fully opensource. A complete operational platform that can scale from a home setup to industrial grade site, even across multiple geographies. Super modular, P2P encrypted networking layer. It supports a long list of miners,… https://t.co/VzXywA6IZc — Paolo Ardoino 🤖 (@paoloardoino) February 2, 2026 This flexibility removes the need for centralized third-party software and reduces dependence on proprietary mining management platforms. “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. Introducing the Mining SDK Alongside MOS, Tether unveiled the Mining SDK, the foundational framework behind the operating system. SDK stands for Software Development Kit. It is a modular toolkit for developers that makes it easier to build new mining software or tools by using ready-made building blocks instead of starting from scratch. While MOS is ready for immediate deployment, the SDK is being released as a collaborative project to be finalized with the open-source community in the coming months. The Mining SDK provides developers with: Pre-built modular components (“workers”) Simple APIs for device and infrastructure integration A UI development kit to quickly build dashboards and internal tools This allows developers and mining companies to build custom mining software without core infrastructure, dramatically lowering development time and cost. Shifting the competitive landscape The move reflects a broader shift in Bitcoin mining, where competition is increasingly being defined by operational efficiency rather than access to proprietary technology. By open-sourcing its mining software stack, Tether aims to lower entry barriers for new miners, enable customization without vendor lock-in, reduce centralization in mining infrastructure software, and strengthen the long-term resilience of the Bitcoin network. Ardoino shared that the goal is to make Bitcoin mining more open, accessible, and competitive; a goal that “ultimately strengthens the resilience of the Bitcoin network.” Also Read: Tether Posts $10B Profit as U.S. Treasury Holdings Hit Record $141B
