It=E2=80=99s going to appear in the Oakland security conference later this year (IEEE Security and Privacy) but we wanted to announce a draft to this community ahead of time. http://www.jbonneau.com/doc/BMCNKF15-IEEESP-bitcoin.pdf One of the main goals of our work is to build a bridge between the computer science research community and the cryptocurrency community. Many of the most interesting ideas and proposals for Bitcoin come from this mailing list and forums/wikis/irc channels, where many academic researchers simply don=E2=80=99t know to look! In fact, we started out by scraping all the interesting posts/articles we could find and trying to figure out how we could organize them. We hope our paper helps some of the best ideas and research questions from the Bitcoin community bubble up and inspires researchers to build on them. We didn=E2=80=99t limit our scope to Bitcoin, but we also decided not to provide a complete survey of altcoins and other next-generation cryptocurrency designs. Instead, we tried to explain all the dimensions along which these designs differ from Bitcoin. This effort has roughly been in progress over two years, though it stopped and restarted several times along the way. If anyone has comments or suggestions, we still have a week before the final version is due, and regardless we plan to continue updating our online version for the forseeable future.
