Tether released its MiningOS software as open source under the Apache 2.0 license on February 3, 2024, when CEO Paolo Ardoino announced the move on X, following its unveiling at the Plan ₿ Forum in San Salvador on February 2. The platform manages Bitcoin mining operations through a single dashboard.
Ardoino described MiningOS, or MOS, as a modular platform designed to support operations across multiple locations. The software features encrypted peer-to-peer networking and broad hardware compatibility. Operators use it to oversee Bitcoin mining infrastructure comprehensively from one interface.
MOS enables detailed monitoring of hardware performance, including metrics on processing power and uptime. It tracks energy usage across devices and facilities to provide precise consumption data. Cooling systems receive oversight for temperature control and efficiency. Site operations, such as ventilation and security, integrate into the dashboard for real-time status updates.
The modular design consists of independent components linked by a shared system. This structure permits users to customize features by selecting or modifying specific modules without affecting the core functionality. Operators tailor the platform to their exact needs, whether for specialized hardware or unique site configurations.

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
MOS operates locally on user devices, eliminating dependence on centralized servers. Peer-to-peer networking allows direct communication between machines, bypassing intermediaries. Tether states this setup enhances reliability by reducing single points of failure and bolsters privacy through encrypted data exchanges confined to the local network.
The Apache 2.0 license permits free use, modification, and distribution of the code. MOS runs on lightweight devices suitable for small-scale home mining setups with a handful of rigs. It scales to industrial deployments managing thousands of machines across distributed sites.
Tether develops a companion Mining SDK alongside MOS. This software development kit equips developers to create custom tools and extensions that integrate with the platform. Community input from the open-source contributors guides the finalization of the SDK framework.
The open-source release targets proprietary mining software providers like Hive OS and Foreman, which impose recurring subscription fees. Tether positions MOS to enable smaller operators to manage operations without ongoing costs. This levels the field against large public mining firms that dominate through economies of scale.
MOS aligns with Tether’s involvement in Bitcoin infrastructure. The company supports the network directly and finances mining projects emphasizing operational efficiency. These projects incorporate renewable energy sources to sustain long-term viability.
Tether reduced certain mining operations in late 2025 amid escalating energy costs. The MOS initiative centers on software provision rather than maintaining physical hardware assets. Tether describes the project as a commitment to decentralized infrastructure development.
By early 2026, Tether held 96,185 BTC, valued at approximately $8 billion. This reserve positioned the company among the largest corporate holders of Bitcoin worldwide.
