Tether’s Mining OS Set to Go Open Source by End-of-Year, Confirms Paolo Ardoino

Tether CEO Paolo Ardoino confirmed that by the end-of-year (EOY), the company will release the Bitcoin Mining OS (MOS) under an open‑source license. This operating system is designed to operate at scales, from small home setups to full industrial mining farms with hundreds of thousands of machines.

Ardoino said that the new version of the OS is currently being tested. It was stated that MOS will feature a modular, peer‑to‑peer IoT architecture supporting a variety of setups, such as air‑cooled, immersion, and different electrical and cooling systems.

Tether’s goal is to reduce the reliance on third‑party vendors, as MOS will give miners autonomy over their infrastructure, breaking dependence on proprietary software providers and reducing vendor lock‑in.

With the public release of its Mining OS, Tether seeks to lower the threshold for new and smaller miners, which should encourage greater engagement and strengthen the decentralization of Bitcoin’s mining hash power. Plus, a more globally distributed miner base makes Bitcoin more resilient and secure against centralization risks.

MOS is expected to integrate with Tether’s decentralized AI platform QVAC, enabling real‑time performance reporting and optimization via machine learning. Not long ago, Ardoino said that by the end of 2025, Tether could become the largest Bitcoin miner in the world, surpassing public mining companies.

Beyond Mining OS

Effective September 1, 2025, Tether will halt USDT redemptions and freeze remaining balances on Algorand, EOS, Omni, Kusama, and Bitcoin Cash SLP. These are deemed ‘legacy’ chains with dwindling usage and low liquidity.

The platform is refocusing on networks with strong developer activity and scalability, primarily Ethereum, Tron, and select Layer‑2s.

A few months ago, Tether partnered with the Ocean mining pool to allocate hash power explicitly aimed at decentralizing block production. Additionally, Tether recently acquired a 70% stake in Adecoagro, a South American agricultural firm, for approximately $600 million. The intention is to integrate USDT into commodities trade, streamline cross-border settlements, and possibly leverage renewable energy for Bitcoin mining.

Speaking of USDT, it remains the dominant global stablecoin, representing over 60% of the market, with a market cap exceeding $160 billion and daily trading volume often above $150 billion.
