ChainCatcher news, Tether and Bitfinex provide Qubes OS with a grant of 100,000 USDT to support the open source development of Qubes OS. Qubes OS is a data security and privacy operating system.

Tether said that by leveraging Xen-based virtualization, Qubes OS is able to isolate different tasks and applications in separate virtual machines called "qubes" and provide a level of security beyond traditional operating systems. This approach provides a highly secure environment for performing sensitive tasks such as financial transactions, accessing sensitive information, or secure communications. (Source link)
