New Modular Operating System Designed to Boost Mining Accessibility and Network Decentralization

Tether, the company behind the world’s largest stablecoin USDT, plans to open-source its Bitcoin mining operating system (MOS) by the fourth quarter of 2025, according to CEO Paolo Ardoino. The initiative aims to enable a broader range of participants to enter the Bitcoin mining industry without depending on expensive third-party software and vendors.

The announcement marks another strategic step by Tether to promote greater decentralization and infrastructure accessibility within the Bitcoin ecosystem.

MOS: Peer-to-Peer Design for Scalable Mining

In a June 10 post on X (formerly Twitter), Ardoino described the forthcoming Bitcoin Mining OS (MOS) as modular, scalable, and built around a peer-to-peer Internet of Things (IoT) architecture. The system is designed to support a variety of existing mining setups, including containers and power distribution systems, making it compatible with a wide range of infrastructure models.

“A horde of new Bitcoin mining companies will be able to enter the game and compete to keep the network safe,” Ardoino stated, underscoring the project’s goal of lowering entry barriers and reinforcing Bitcoin’s decentralized security model.

The open-source nature of MOS is expected to reduce startup costs and allow smaller mining operators to build, customize, and maintain their operations with more autonomy.

Part of Broader Push to Decentralize Bitcoin Mining

Tether’s mining ambitions extend beyond software. In April 2025, the company partnered with Ocean, a Bitcoin mining pool focused on decentralized block building, by contributing its current and future hashrate to the protocol.

That partnership — and now the MOS initiative — reflect Tether’s broader effort to reinvigorate decentralization across the Bitcoin mining sector, which has come under criticism in recent years for growing centralization around a handful of large mining firms.

“We’re not just supporting Bitcoin — we’re helping shape its future infrastructure,” Ardoino said.

Large Miners Still Hold the Advantage, but Diversification is Rising

Tether’s move comes at a time when Bitcoin mining is undergoing a period of rapid evolution. Large-scale mining firms continue to benefit from their economies of scale, including low-cost electricity contracts, access to capital, and greater hashing power. However, even these companies are diversifying their revenue streams to stay profitable, especially in the wake of the 2024 Bitcoin halving that slashed block rewards in half.

Some firms have pivoted toward Bitcoin treasury strategies, accumulating BTC in anticipation of future price appreciation. Others are repurposing existing infrastructure to support artificial intelligence (AI) workloads, which often command higher margins.

Hive Digital, for example, reported that AI-related revenues have exceeded those from crypto mining. As a result, the company has shifted more investment toward its AI operations.

“Institutions are much more interested in us with our AI than Bitcoin,” said Frank Holmes, executive chairman of Hive Digital, in an earlier interview.

Smaller Firms Are Consolidating Around Bitcoin

While some companies are exploring new verticals, others are doubling down on Bitcoin. In one such example, Bitcoin miner Cango reportedly generated over $100 million worth of Bitcoin in just two months after divesting from its non-mining business lines.

The company’s strategy reflects a back-to-basics approach, where all available resources are directed toward pure-play Bitcoin mining.

A Decentralized Future Through Open-Source Tools

Tether’s move to open-source its mining operating system may empower a new wave of independent miners, particularly those in emerging markets or regions with access to surplus energy. By removing reliance on costly vendor ecosystems and central infrastructure providers, Tether aims to democratize access to mining and reinforce the resilience of the Bitcoin network.

While further technical details are expected ahead of the Q4 2025 launch, the company says it will provide comprehensive documentation, development kits, and community governance features for the project.

Conclusion

Tether’s upcoming open-source Bitcoin Mining OS could mark a significant step forward in democratizing access to Bitcoin mining and reducing dependence on centralized vendors. With a rollout expected by the end of 2025, the project aligns with the company’s broader mission to support decentralization across the Bitcoin ecosystem.

As the mining industry continues to evolve in the wake of the 2024 halving, open-source tools like MOS could serve as a counterbalance to consolidation, enabling smaller players to thrive in an increasingly competitive environment — and ensuring that Bitcoin’s foundational principle of decentralization remains intact.
