Early Attempts At E-Currencies DigiCash David Chaum lead the first serious attempt at building digital money, founding the electronic money corporation DigiCash Inc in 1989. DigiCash used novel cryptography to unsure user privacy while solving the double spend problem. The underlying algorithm was known as eCash, first published in 1982 and later improved by later cryptographers. It lost out in user adoption against credit cards and less private payment systems like PayPal. DigiCash declared bankruptcy in 1998. MojoNation Evil Geniuses for a Better Tomorrow was a startup company founded by Jim McCoy to create MojoNation. Mojo was a digital cash currency.The only application built onEGTP/Mojo framework was a distributed file publishing system. MojoNation ceased operation as a commercial enterprise in February 2004, when it was replaced by the noncommercial Mnet Project. Former employees Bram Cohen went on to create BitTorrent and Zooko Wilcox-O'Hearn created Mnet out of the MojoNation source code.
