Tether launches open-source Bitcoin mining OS to challenge proprietary software

Tether has released an open-source operating system for bitcoin BTC mining, offering miners a new alternative to proprietary, vendor-controlled software as the company continues to broaden its interests in crypto infrastructure.

The stablecoin issuer said Monday it has open-sourced MiningOS, or MOS, an operating system designed to manage, monitor, and automate bitcoin mining operations across deployments ranging from small home setups to large industrial sites. Tether first previewed plans for an open-source mining operating system last year, arguing that new entrants should be able to compete in bitcoin mining without depending on expensive, closed-source management tools. Other firms like Jack Dorsey’s Block have also pushed for more open mining infrastructure.

Per Tether, MOS is built around a modular, peer-to-peer architecture that allows operators to manage mining activity without relying on centralized services.

The system is designed to coordinate hardware, energy usage, device health, and site-level infrastructure within a single operational layer, giving miners wider visibility across their operations rather than relying on fragmented software stacks.

"Mining OS is built to make Bitcoin mining infrastructure more open, modular, and accessible," said Paolo Ardoino, Tether’s CEO. He noted the system can scale from individual machines to industrial-grade sites spread across multiple geographies, without locking operators into third-party platforms.

MOS has been released under an Apache 2.0 open-source license and is designed to be hardware-agnostic, according to Tether. The company also announced a Mining SDK, the framework underpinning MOS, which it said will be released and developed further in collaboration with the open-source community in the coming months.

Beyond USDT

Tether continues to expand beyond its core stablecoin business.

The company reported more than $10 billion in net profit in 2025, driven largely by interest income on reserves, and has increasingly positioned itself across mining, payments, and infrastructure.

Tether has also rolled out new products in recent months, including a push into tokenized commodities like gold and a U.S.-focused stablecoin dubbed USAT, while Ardoino himself has downplayed direct involvement in U.S. stablecoin yield debates.
