The Cypherpunk Manifesto was a document written by Eric Hughes in 1993. It outlined the principles of a movement focused on using cryptography and technology to empower individuals and protect privacy. It emphasized the need for privacy in the digital age and the importance of cryptography as a means of achieving it. The manifesto called for a decentralized electronic payment system, and encouraged the use of pseudonyms and anonymous communication online. The cypherpunk movement brought together computer scientists, activists, and individuals concerned with privacy and freedom from government surveillance. Their ideas and technologies have had a profound impact on the development of digital privacy and security.
