Why use a VPN? Mysterium Network is a fast and scalable transport security layer. Mysterium is reinventing privacy, starting with decentralizing VPN on blockchain which means that our architecture can’t actually keep logs of your traffic. Instead, your traffic data is distributed across the network with no single node having complete access to who you are and what you are doing. We have been open source from day one. Everything is transparent. You can check our source code and even contribute.
