On February 2, Tether introduced MiningOS (MOS) at the Plan 9 Forum in San Salvador. MiningOS is an open-source Bitcoin mining operating system engineered for operators of all sizes. It is designed to unify various aspects of bitcoin mining, such as hardware performance, energy consumption, site infrastructure, and operational data, into a single control layer. This integration facilitates a more seamless operation for different mining setups, ranging from lightweight hardware implementations to vast industrial installations.
MiningOS (MOS) is built with a peer-to-peer and modular architecture. This architecture allows flexible deployment across a wide range of mining operations. MOS is marketed as a production-ready system deployable on lightweight hardware as well as on industrial sites that can manage hundreds of thousands of machines. The project is presented for mining operators of all sizes.
MOS can control, observe, and automate Bitcoin mining through a single control layer. That control layer integrates hardware performance, energy consumption, site infrastructure, and operational data. The system is described as treating each component as a coordinated “worker” within one operating system, allowing operators to see and manage their entire setup in real time. MOS’s modular, peer-to-peer design is compatible with both small-scale and large-scale deployments while operating through the unified control layer.
The Bitcoin network hashrate rose from about 800 EH/s at the start of 2025 to around 1.15 ZH/s in October. Bitcoin mining difficulty reached record levels during that period. The network hashrate then fell below 1,000 EH/s in early 2026, reaching about 870 EH/s at points.
The post‑halving block reward is 3.125 BTC. Transaction fees declined. Hashprice was around $35–$40 per PH/s per day in late 2025. The average cash cost for public miners was around $44.
Tether reported more than $10 billion in net profit in 2025 total and expanded into XAUT and the MiniPay wallet. The Mining SDK will be released together with the open‑source community alongside MOS.
Tether launched MiningOS (MOS) on February 2 at the Plan 9 Forum in San Salvador as an open‑source Bitcoin mining operating system designed for mining operators of all sizes. MOS integrates hardware performance, energy consumption, site infrastructure, and operational data into a single control layer that can control, observe, and automate Bitcoin mining in real time. Tether presented MOS as a production‑ready system and said the decision to open‑source the mining stack was intended to minimize barriers to entry and lessen reliance on proprietary or centralized third‑party software providers.
