The system is built on Holepunch peer-to-peer protocols, eliminating the need for centralized services and third-party dependencies.
The software is released under the Apache 2.0 open license, ensuring users can freely use, modify, and distribute the code for both commercial and non-commercial purposes.
“For too long, the mining industry has been limited to closed systems and proprietary tools. MiningOS changes that […]. No black boxes. No lock-ins. No restrictions,” stated the issuer of USDT.
Tether first announced plans for open-source Bitcoin mining software in June 2023, emphasizing the importance of allowing new participants to "enter the game and compete" without reliance on expensive third-party vendors.
Tether and Opera
The issuer of USDT has partnered with browser developer Opera to enhance financial accessibility in emerging markets. As part of this collaboration, Tether has integrated its stablecoin and tokenized gold XAUT into the MiniPay self-custodial wallet ecosystem.
The initiative aims to provide users in regions with unstable national currencies (Africa, Latin America, and Southeast Asia) easy access to dollar-denominated digital assets for daily transactions, remittances, and savings.
“Tether's mission has always been to provide a simple and reliable store of value to those who need it most,” commented Ardoino.
MiniPay operates in 60 countries and has 12.6 million active wallets. In the fourth quarter, the user base of the service grew by 50%, primarily in emerging markets.
For reference, Tether's net profit for 2025 reached $10 billion.
