Stablecoin issuer Tether is set to open-source its Bitcoin Mining Operating System (MOS) to enable mining companies of all sizes to run and manage mining infrastructure without relying on third-party software, CEO Paolo Ardoino said Monday.
Designed to efficiently manage and scale Bitcoin mining operations, Tether’s MOS integrates all key components of a mining site into a peer-to-peer, serverless network, allowing seamless communications between devices.
According to Ardoino, the mining software platform features a peer-to-peer IoT architecture that can operate at different scales, from small Raspberry PI setups to large facilities managing hundreds of thousands of miners.
Ardoino expects the decision to open-source the MOS will help level the “playing field” between small and large mining operators. In other words, small and mid-sized players will be given the tools to compete with industry giants.
Tether’s CEO also sees the move as a way to strengthen network decentralization and security, as more participants can join the network and keep it safe.
“A horde of new Bitcoin mining companies will be able to enter the game and compete to keep the network safe. No need anymore for any 3rd party hosting software,” said Ardoino in a Monday statement on X. “MOS will create an even playing field, reducing the gap between publicly listed companies and smaller players.”
Ardoino added that future developments could include integration with AI tools to enhance production and performance analysis using the data generated by the Mining OS.
The team is currently working on documentation, user guides, and preparing repositories for community access, with the release targeted for Q4 2025, as noted by Ardoino.
In recent years, Tether has expanded beyond its stablecoin business to include artificial intelligence, Bitcoin mining, and education.
By mid-2025, Tether had invested around $2 billion in Bitcoin mining and energy-related businesses, Ardoino announced during his remarks at the 2025 Bitcoin Conference in Las Vegas.
“We invested 2 billion in energy production, and Bitcoin mining actually is a bit more than that,” said Ardoino. “Something that we have been very shy to say, but I think that it’s very realistic that by the end of the year, Tether will be the biggest Bitcoin miner in the world, even including all the public companies.”
