Clarke designed Freenet; which he completed as a graduation requirement in the summer of 1999. "Freenet: A Distributed Anonymous Information Storage and Retrieval System" (Clarke, Sandberg, Wiley, Hong, 2001) have become one of the most cited computer science articles in 2002. Freenet offers two modes of protection; the dark net mode in which it connects only to friends, and an open net-mode in which it connects to any other Freenet user. When the user switches to pure dark net operation, Freenet becomes very difficult to detect from the outside. On 11 February 2015, Freenet received the SUMA-Award for “Protection against total surveillance”. (SUMA, 2015). The year 2003 have brought the initial release of Invisible Internet Project (I2P), uses include anonymous web surfing, chatting, blogging, and file transfers, the software is free, and open source.

The citation read, "Using free software, Tor has enabled roughly 36 million people around the world to experience freedom of access and expression on the Internet while keeping them in control of their privacy and anonymity. Its network has proved essential in dissident movements in both Iran and more recently Egypt." (Sullivan,
