I wrote a paper about the technical basis of digital currencies for a seminar at the university. It is an introduction into the market of digital currencies and a technical description of the most important systems: Bitcoin as well as the Bitcoin forks Litecoin, Peercoin (PPCoin) and Primecoin. So if you are interested in digital currencies in general or one of these systems, go read my paper 😉
