Crypto-anarchism (or crypto-anarchy) is a cyber-spatial realization of anarchism. Crypto-anarchists employ cryptographic software to evade prosecution and harassment while sending and receiving information over computer networks, in an effort to protect their privacy and political freedom.
By using cryptographic software, the association between the identity of a certain user or organization and the pseudonym they use is made difficult to find, unless the user reveals the association. It is difficult to say which country's laws will be ignored, as even the location of a certain participant is unknown. However, participants may in theory voluntarily create new laws using smart contracts or, if the user is pseudonymous, depend on online reputation.
"Crypto-" comes from the Ancient Greek kruptós, "concealed, private, hidden, secret". It should, however, not be confused with the use of the prefix "" to indicate an ideology or system with an intentionally concealed or obfuscated "true nature". For example, some would use the term "crypto-fascist" to describe an individual or organization that holds fascist views and subscribes to fascist doctrine but conceals their agenda so long as these doctrines remain socially unacceptable. However, Timothy C. May's "Cyphernomicon" indicates that the term "crypto-anarchist" was partially intended as a pun on this usage, even though he did not intend to conceal his beliefs or agenda.
One motive of crypto-anarchists is to defend against surveillance of computer networks communication. Crypto-anarchists try to protect against government mass surveillance, such as PRISM, Tempora, telecommunications data retention, the NSA warrantless surveillance controversy, Room 641A, the FRA and so on. Crypto-anarchists consider the development and use of cryptography to be the main defense against such problems, as opposed to political action.
