Stablecoin issuer Tether has released its long-anticipated open-source Bitcoin mining software, aiming to lower entry barriers and reduce reliance on proprietary mining systems.
Announced Monday via X, the new software, MiningOS (MOS), is designed as a modular, scalable operating system that can support everyone from home miners to large institutional operations.

According to Tether, the launch is part of a broader effort to inject transparency and openness into Bitcoin’s mining infrastructure, which has traditionally been dominated by closed, vendor-locked platforms.
MiningOS is built for scale, flexibility, and peer-to-peer control
MiningOS operates as a self-hosted mining architecture that connects devices through an integrated peer-to-peer network, allowing miners to manage operations without centralized intermediaries.
The platform includes a configurable interface that lets miners adjust settings based on their size, output goals, and geographic spread. Tether CEO Paolo Ardoino described MiningOS as a “complete operational platform” capable of scaling from small home setups to industrial-grade mining facilities across multiple locations.
Tether first revealed plans for an open-source mining operating system in June 2025, emphasizing the need for new miners to compete without being dependent on costly third-party vendors.
Part of Tether’s broader push beyond stablecoins
With MiningOS, Tether joins other crypto heavyweights such as Jack Dorsey’s Block in releasing open-source Bitcoin mining software. However, unlike Block’s stack, which is tailored specifically to its own hardware, Tether says MiningOS is compatible with a wide range of existing mining infrastructure.
The software is released under the Apache 2.0 license, allowing unrestricted use, modification, and derivative works. It is built on Holepunch peer-to-peer protocols, which Tether says eliminates centralized services, backdoors, and third-party dependencies.
The launch also reflects Tether’s expanding footprint beyond stablecoins. Throughout 2025, the company increased investments across tokenization, artificial intelligence, and decentralized finance, while continuing to accumulate Bitcoin and gold as part of its reserves strategy.
