The aim here is to supersede existing VPNs in order to fight increasingly more powerful authoritarianism and surveillance. Unlike traditional centralized VPNs that can be de-anonymized by a global passive adversary - like the NSA - based on their traffic patterns, Nym adds noise ("cover traffic") to existing Internet communications. Similar to Tor, Nym routes each packet separately over a decentralized network of servers, but unlike Tor, mixes traffic and adds noise at each hop. After being introduced at HOPE five years ago, NymVPN has now shipped. NymVPN is an easy to use app for all major operating systems that makes using the Nym network as easy as using a traditional VPN for ordinary people, with both a "fast" and "anonymous" mode. The "fast" mode features speeds comparable to centralized VPNs using the same decentralized network as the mixnet, but without mixing. Via the SDK, the Nym mixnet remains free to use by hackers to build the next generation of privacy infrastructure.
