Tether Launches Open-Source Bitcoin MiningOS to Challenge Proprietary Mining Software

Tether launched MiningOS (MOS) on February 3, 2026, an open-source operating system for Bitcoin mining aimed at reducing reliance on closed, vendor-controlled platforms. The stablecoin issuer positions MOS as a transparent, modular alternative that scales from hobbyist rigs to industrial operations. Built on Holepunch peer-to-peer protocols and released under the Apache 2.0 license, MOS uses a self-hosted architecture to eliminate centralized dependencies. Operators can manage hardware and adjust settings via a companion platform tailored to their scale and output needs. Tether CEO Paolo Ardoino described it as a “complete operational platform” enabling global deployment without lock-in. The move aligns Tether with other open-source mining initiatives, including those by Block, and follows its initial announcement of the project in June 2025.
