What is a Cypherpunk?


Wikipedia defines “Cypherpunk” as follows (2018-05-26):

A cypherpunk is any activist advocating widespread use of strong cryptography and privacy-enhancing technologies as a route to social and political change. Originally communicating through the Cypherpunks electronic mailing list, informal groups aimed to achieve privacy and security through proactive use of cryptography. Cypherpunks have been engaged in an active movement since the late 1980s.

The following paragraphs are also worth including:

Until about the 1970s, cryptography was mainly practiced in secret by military or spy agencies. However, that changed when two publications brought it out of the closet into public awareness: the US government publication of the Data Encryption Standard (DES), a block cipher which became very widely used; and the first publicly available work on public-key cryptography, by Whitfield Diffie and Martin Hellman.

The technical roots of Cypherpunk ideas have been traced back to work by cryptographer David Chaum on topics such as anonymous digital cash and pseudonymous reputation systems, described in his paper “Security without Identification: Transaction Systems to Make Big Brother Obsolete” (1985).

In late 1992, Eric Hughes, Timothy C. May and John Gilmore founded a small group that met monthly at Gilmore’s company Cygnus Solutions in the San Francisco Bay Area, and was humorously termed cypherpunks by Jude Milhon at one of the first meetings - derived from cipher and cyberpunk. In November 2006, the word was added to the Oxford English Dictionary.

It should be noted that while the term “cypherpunk” is a humourous reference to the contemporary “cyberpunk” scene, the two philosophies/scenes are not as closely related as the name suggests.

In terms of how “cypherpunks” would define themselves, we can actually look to founding cypherpunk Eric Hughes’s words for a much more succinct definition:

Cypherpunks write code.

This comes from “A Cypherpunk’s Manifesto” which was posted by Hughes to the Cypherpunks Mailing List on 9th March 1993. In this document he argues for a cypherpunk ethos which elevates action over talk. He believed that instead of debating the fineries of theoretical systems, cypherpunks should get to work writing the cryptographic tools that will enable them to bring more privacy and liberty into the word.

Modern-day cypherpunks still hold that ethos close to their heart. Just as “The Crypto-Anarchist Manifesto” was required reading for that section, “A Cypherpunk’s Manifesto” is essential reading for all newcomers.
