DigiCash Inc. was an electronic money corporation founded by David Chaum in 1990. DigiCash transactions were unique in that they were anonymous due to a number of cryptographic protocols developed by its founder.[1] DigiCash declared bankruptcy in 1998, and subsequently sold its assets to Ecash, another digital currency company, which was acquired by InfoSpace on Feb. 19, 2002.
