Tether Launches Open‑Source MiningOS to Challenge Bitcoin Mining Giants
Stablecoin issuer Tether has launched an open-source Bitcoin mining working system, a transfer that locations it immediately into the mining infrastructure layer historically dominated by massive, vertically built-in companies.
The software program known as Mining OS, or MOS, and was announced on Feb. 2 through the Plan 9 Forum in San Salvador and is being marketed as a production-ready system that may be deployed by mining operators of all sizes.
Tether claimed MOS could be used to management, 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 With a Single System
Mining of Bitcoin normally makes use of disjointed software program stacks to handle machine utilization, energy infrastructure, cooling, and logistics of the location.
MOS seeks to substitute that patchwork by treating every part as a coordinated “employee” inside one working system, permitting operators to see and handle their total setup in actual time.
The firm claimed that the system screens extra than simply hashrate but in addition screens power effectivity, system well being, and site-level infrastructure.
The firm 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 a whole bunch 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 announced a Mining Software Development Kit, or Mining SDK, which is the bottom of MOS, that shall be launched along with the open-source neighborhood 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 decrease the limitations to entry in addition to reduce its reliance on proprietary platforms.
Bitcoin Miners Struggle for Breathing Room After 2025 Downturn
The launch comes at a tough second for the Bitcoin mining sector.
Miners skilled some of the extreme profitability squeezes within the business’s historical past because the Bitcoin value continued to expertise a downturn since 2025.
Network hashrate climbed from around 800 exahash per second initially of the 12 months to a peak of roughly 1.15 zettahash per second in October, pushing mining issue to report ranges.
At the identical time, the post-halving block reward of three.125 BTC and declining transaction charges diminished income per unit of hash.
By late 2025, the hash value had fallen to round $35 to $40 per petahash per second per day, whereas the common money value for public miners was estimated close to $44.
All-in manufacturing prices, together with depreciation, have been significance larger.
Even operators with efficient fleets and low-cost power have been working shut to breakeven, and debt ranges rose as corporations financed new {hardware} and infrastructure upgrades.
Entering early 2026, some stress has eased. Network hashrate has fallen below 1,000 EH/s for the primary time since September, dipping to 870 EH/s at factors following winter storms and diminished profitability.

Difficulty has adjusted downward a number of occasions, and hashprice has proven modest enchancment.
Analysts have mentioned the pullback might quickly enhance margins for remaining miners, although competitors stays intense.
Against this backdrop, Tether’s transfer into mining software program provides to its increasing footprint throughout the digital asset ecosystem.
Best often called the issuer of USDT, Tether reported more than $10 billion in net profit in 2025 and has expanded into tokenized gold by way of XAUT, and cost partnerships like Opera’s MiniPay pockets.

Bitcoin Mining is advanced.
Mining OS by Tether (MOS) makes it easy.
Bitcoin’s community hashrate has slipped under 1,000 exahash per second (EH/s) for the primary time since mid-September.
