Overstock.com is accepting bitcoin as a form of payment.
Customers can use that "cryptocurrency" in addition to Visa, MasterCard and PayPal on the website to buy merchandise.
"This is historic. Digital currency will be an important part of the future and Overstock is excited to be the first major online shopping retailer to accept it," states Overstock.com Chairman and CEO Patrick M. Byrne. "As one who believes in limited government, this attracts me because it is a form of money that no government mandarin can will it into existence."
Bitcoin is operated by a peer-to-peer network made up of thousands of computers run by people around the world and doesn't answer to a central authority. It is like gold in that its supply is constrained mathematically to up to 21 million units that will grow in a predictable manner.
