Tether to start open-sourcing its Bitcoin mining OS

Stablecoin issuer Tether plans to open-source its Bitcoin Mining Operating System, allowing companies of all sizes to access and operate mining infrastructure independently, without relying on proprietary third-party software. 

The announcement was made by Tether (USDT) CEO Paolo Ardoino, who described the initiative as a push to “make mining great again.”

Tether’s MOS is built with a scalable, peer-to-peer IoT architecture that can adapt from small setups using Raspberry Pi boards to large mining sites managing hundreds of thousands of machines. 

It already supports a wide array of mining hardware vendors, air-cooled and immersion containers, and electrical components such as thermostats.

By open-sourcing the platform, Tether aims to reduce barriers to entry for new and smaller mining firms. Ardoino said this could help decentralize the Bitcoin (BTC) network by enabling more participants to contribute to mining, thereby enhancing security and reducing the concentration of power held by publicly listed mining giants.

“New Bitcoin mining companies will be able to enter the game and compete to keep the network safe,” Ardoino said on X. “MOS will create an even playing field.”

Custom plugins

A key feature of the open-source MOS is its modular plugin system. Developers will be able to create and share custom plugins tailored to specific hardware or site needs, fostering a collaborative development environment. 

Tether also envisions integrating MOS with its internal data platform QVAC and artificial intelligence tools for performance optimization based on mining data.

The open-sourcing could prove especially impactful for small-to-mid-sized enterprises producing their own energy, such as solar or hydro-powered businesses, who may now find it easier to participate in Bitcoin mining using surplus electricity.

Tether is preparing the MOS release for Q4 2025, including documentation and user guides. The move signals a broader shift in the mining industry toward open access and decentralized control of infrastructure.
