We are talking with J Ringo, the project organizer of Gridcoin, a POS-based cryptocurrency that rewards users for participating on the BOINC network. Gridcoin uses peer-to-peer technology to operate with no central authority - managing transactions, issuing money and contributing to scientific research are carried out collectively by the network. With a strong community and comprehensive branch-based development strategy, Gridcoin has been going strong for over 5 years.
