The Cypherpunks is a group of cryptographers and privacy activists. The Cypherpunk movement started in the 1990s, centered around discussions on online privacy and anonymity. Members of this group believed strongly that the use of strong cryptography and privacy-enhancing technologies could bring about social and political change.

The Cypherpunks were at the forefront of promoting cryptography and privacy, and their influence is still evident today in the fields of cybersecurity and blockchain technologies.
