Cryptoanarchism is a philosophy that advocates using strong cryptography to protect privacy and personal freedom. Cryptoanarchists are people who support the philosophy of cryptoanarchism. They believe that cryptography protects people from online surveillance and believe that the laws of mathematics are stronger than human laws and that without encryption of messages and information, people's privacy will suffer. Their global goal is the Internet of trust. This phenomenon can be attributed to the sphere of socio-political ideology aimed at the fight for freedom of speech, privacy and private correspondence. Only as the main tool of this struggle, crypto-anarchists see not strikes, rallies and street protests, but mathematical algorithms and deep encryption. Is it possible to implement socio-technological models in cyberspace, which many modern experts consider utopias? The book introduces the opinions of authoritative experts in various fields of modern science.
