History
Precursory ideas for digital currencies were presented in electronic payment methods such as the Sabre (travel reservation system). In 1983, a research paper titled "Blind Signatures for Untraceable Payments" by David Chaum introduced the idea of digital cash. In 1989, he founded DigiCash, an electronic cash company, in Amsterdam to commercialize the ideas in his research. It filed for bankruptcy in 1998.
