Bitcoin miners get an open-source alternative as Tether launches MiningOS

Tether has released an open-source operating system for bitcoin mining, pitching it as a way to make running mining infrastructure simpler while reducing reliance on closed, vendor-controlled software.

The stablecoin issuer said on Monday that it has rolled out MiningOS (MOS), describing it as a modular, scalable mining operating system designed for anyone from hobbyist miners to large institutions.

The stack is intended to remove the “black box” nature of many mining setups, where hardware and monitoring tools are tightly tied to proprietary platforms.

“MiningOS changes that — introducing transparency, openness, and collaboration into the core of Bitcoin infrastructure,” Tether said on the project’s website, adding that the system is built with “no lock-in.”

According to Tether, MOS uses a self-hosted architecture and communicates with connected devices through an integrated peer-to-peer network, allowing operators to manage mining activity without relying on centralized services. The company said miners can adjust settings through a companion platform depending on the scale of their operation and output requirements.

CEO Paolo Ardoino called MOS a “complete operational platform” that can scale from a home setup to an “industrial grade” site spread across multiple geographies.

Tether first previewed plans for an open-source mining OS in June last year, arguing that new miners should be able to compete without having to depend on expensive third-party vendors for software and management tools.

The release places Tether alongside other crypto firms that have pushed open-source mining infrastructure, including Jack Dorsey’s Block.

MOS is released under the Apache 2.0 license and built on Holepunch peer-to-peer protocols, with the aim of keeping the stack free of third-party dependencies.
