Stablecoin issuer Tether has launched an open-source Bitcoin mining working system, a transfer that locations it straight into the mining infrastructure layer historically dominated by giant, vertically built-in corporations.
The software program is known as Mining OS, or MOS, and was introduced on Feb. 2 throughout the Plan 9 Discussion board in San Salvador and is being marketed as a production-ready system that may be deployed by mining operators of all sizes.
Bitcoin Mining is complicated.
Mining OS by Tether (MOS) makes it easy.
Introducing MOS — the open-source working system for actual mining infrastructure.
Modular. Scalable. Constructed for power + {hardware} + knowledge.

Tether claimed MOS could be used to regulate, observe, and automate Bitcoin mining by way of a single management layer by integrating {hardware} efficiency, power consumption, website infrastructure, and operational knowledge.
Tether’s MOS Replaces Patchwork Mining Software program With a Single System
Mining of Bitcoin often makes use of disjointed software program stacks to handle machine utilization, energy infrastructure, cooling, and logistics of the positioning.
MOS seeks to interchange that patchwork by treating every element as a coordinated “employee” inside one working system, permitting operators to see and handle their complete setup in actual time.
The corporate claimed that the system screens extra than simply hashrate but additionally screens power effectivity, gadget well being, and site-level infrastructure.
The corporate additionally famous that it has a peer-to-peer and modular structure that may be deployed on light-weight {hardware} in small deployments or on industrial websites with tons of of 1000’s of machines.
Tether characterised MOS as strong and adaptable, and never depending on the centralized third-party software program suppliers.
Tether additionally introduced a Mining Software program Growth Package, or Mining SDK, which is the bottom of MOS, that will likely be launched along with the open-source group within the close to future, alongside the working system.
Tether CEO Paolo Ardoino noticed that the transfer to open-source the mining stack was to attenuate the boundaries to entry in addition to reduce its reliance on proprietary platforms.
Bitcoin Miners Battle for Respiratory Room After 2025 Downturn
The launch comes at a tough second for the Bitcoin mining sector.
Miners skilled one of the vital extreme profitability squeezes within the trade’s historical past because the Bitcoin worth continued to expertise a downturn since 2025.
Community hashrate climbed from round 800 exahash per second at the beginning of the 12 months to a peak of roughly 1.15 zettahash per second in October, pushing mining problem to file ranges.
Bitcoin’s community hashrate has slipped under 1,000 exahash per second (EH/s) for the primary time since mid-September.#Bitcoin #Mininghttps://t.co/yF5wm7389Z

On the similar time, the post-halving block reward of three.125 BTC and declining transaction charges lowered income per unit of hash.
By late 2025, the hash worth had fallen to round $35 to $40 per petahash per second per day, whereas the typical money value for public miners was estimated close to $44.
All-in manufacturing prices, together with depreciation, had been significance greater.
Even operators with environment friendly fleets and low-cost energy had been working near breakeven, and debt ranges rose as firms financed new {hardware} and infrastructure upgrades.
Getting into early 2026, some stress has eased. Community hashrate has fallen under 1,000 EH/s for the primary time since September, dipping to 870 EH/s at factors following winter storms and lowered profitability.
Problem has adjusted downward a number of instances, and hashprice has proven modest enchancment.
Analysts have mentioned the pullback may quickly enhance margins for remaining miners, although competitors stays intense.
Towards this backdrop, Tether’s transfer into mining software program provides to its increasing footprint throughout the digital asset ecosystem.
Finest generally known as the issuer of USDT, Tether reported greater than $10 billion in internet revenue in 2025 and has expanded into tokenized gold by way of XAUT, and fee partnerships like Opera’s MiniPay pockets.
