Mysterium VPN is a decentralized, peer-to-peer virtual private network developed by Mysterium Network, a Swiss-based open-source project founded in 2017. Unlike traditional VPNs that rely on centralized servers, Mysterium VPN leverages a global network of residential nodes contributed by users, enhancing privacy and reducing the risk of censorship. The service employs advanced encryption protocols, including WireGuard®, to ensure secure and fast connections across various platforms such as Windows, macOS, Linux, Android, and iOS. With a pay-as-you-go model facilitated by blockchain technology, users can access over 135 countries without the need for subscriptions or contracts.
