Tuesday, the University of Pittsburgh launched the first Bitcoin-only journal, Ledger, which tackles the interdisciplinary world of cryptocurrency research.

You might ask, how much Bitcoin research can there possibly be? Bitcoin has seen scrolls of papers, exploring everything from improving information propagation across the Bitcoin network to advice for regulating cryptocurrency-inspired financial instruments. Ledger's editors argue that cryptocurrency is too sprawling of a field of study for any "traditional journal." 

The peer-reviewed academic journal will cover technical, social, economic, and philosophical cryptocurrency developments. A paper might address, for instance, the new cryptocurrency algorithm designs, or a macroeconomic study.
