Refereum, as its site describes it, uses the blockchain to connect gamers and viewers alike to earn cash and cash prizes depending on projects. It is currently partnered with Twitch and Unity and the opensource is in its beta phase. The coin sale will start on December 12, 2017.
What looks funny is that I haven't even received or reached the proper points to be in the diamond tier, but I'm already listed as one. Probably because all the referred users don't do much in the site. I believe its a great tech and idea and you can sign up under my link if you want to get started: https://earn.refereum.com/?refid=bunxv53xwm
