“Fedimint” is an abbreviation of the words, “federated” and “mint.” The concept was originally conceived in 1983 by renowned computer scientist and cryptographer, David Chaum, and later used to create e-cash, a primordial, albeit centralized, version of today’s cryptocurrencies. E-cash used blind signatures to preserve user privacy. Blind signatures allow a sender’s message to be cryptographically blinded (or hidden) before being digitally signed by the recipient, thereby preserving the sender’s anonymity.
