Eastman Kodak announced it would launch its own cryptocurrency At CES this week. The once-bankrupt company’s stock almost tripled on the news that it was also jumping on the blockchain bandwagon. Come Thursday, however, it was down 12% in trading. Kodak's technology could actually be a big help in tracking the use of copyrighted images on the internet. As part of the new service, photographers can license their photos through KodakOne and will be paid in KodakCoin.
