What Was the First Cryptocurrency?
Bitcoin is commonly thought to be the first cryptocurrency, but there were several attempts create digital currency before Bitcoin. The first cryptocurrency was eCash, developed by the company DigiCash in 1990. The concept and company were created by cryptographer David Chaum, who in 1983 published a paper titled "Blind Signatures for Untraceable Payments." Several other attempts ultimately led up to Bitcoin's creation, but it took more than 20 years for cryptocurrency to evolve to its current state.
