Seems like Blackcoin fits into our criteria.
I don't know whether to go on with the publication of results of my research since I'm not seeing that anybody contributes anything of value any more. The idea of this thread is to make a collective research, if it's only me working I can keep my results for myself.
I would like to contribute but sometimes (e.g. this week) my time is limited. However I think I agree with Blackcoin and Burst (I actually was a bit surprised that Burst had no premine, but it seems to be true according to their ANN.)
