A Cypherpunk is a certain type of activitist that doesn’t believe in the current state of society with respect to e.g. privacy, banking, information transmission and more. Instead, the Cypherpunks propose a more wide-spread adoption of e.g. blockchain technology to strengthen each individual’s privacy. The Cypherpunks’ “bible” is “A Cypherpunk’s Manifesto” written by Eric Hughes in 1993.
