Steem arrived on the scene to signfigant scorn from people in the blockchain world. Perhaps the catalyst was poor documentation and communications ahead of it's launch, or the wild pump/dump of it's token. Yet Steem continues to be one of the most interesting *live *experiments in the blockchain space. It is one of the few projects that can boast tens of thousands of "mainstream" users, a live implementation of DPOS consensus, and an application that works without micropayments, instead using inflation to reward participants.

I haven't seen much robust analysis of the technology underlying Steem (Graphene), it consensus algorithm, or it's economic modeling and I can't help but wonder if thi
