Very glad to see this workshop taking place. Just hope that it will provide the required direction for the way forward as far as bitcoin is concerned.
Proposals for presentations can be submitted until September 12, 2015. The committee encourages prospective participants to post a paper, simulation results and source code or “whatever other type of research material” they have. However, they point out that publishing a paper is not required, provided there is an adequate presentation plan and summary. Their main goal is to ensure that all good ideas are given consideration.
