Tether to Release Open-Source Bitcoin Mining OS by Year-End

Tether CEO Paolo Ardoino confirmed that by the end of the 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 ranging from small home setups to full industrial mining farms with hundreds of thousands of machines.

Ardoino stated that the new version of the OS is currently being tested. It will feature a modular, peer-to-peer IoT architecture supporting various setups, including air-cooled, immersion, and differing electrical and cooling systems.

Tether aims to reduce reliance on third-party vendors, as MOS will give miners autonomy over their infrastructure, breaking dependence on proprietary software and reducing vendor lock-in.

With the public release of its Mining OS, Tether seeks to lower the threshold for new and smaller miners, encouraging greater engagement and strengthening the decentralization of Bitcoin’s mining hash power. A more globally distributed miner base enhances Bitcoin’s resilience and security against centralization risks.

MOS is also expected to integrate with Tether’s decentralized AI platform QVAC, enabling real-time performance reporting and optimization through machine learning. Recently, Ardoino mentioned 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, 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 aimed at decentralizing block production. Tether also acquired a 70% stake in Adecoagro, a South American agricultural firm, for approximately $600 million, with the intention of integrating USDT into commodities trade, streamlining cross-border settlements, and possibly leveraging 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.
