Do I have to fill out the "mining social proofs"? I think they are tweets, Bitcointalk posts, etc. to prove that you are serious about Hadron. Or were these an alpha version tool?
So the reason we have Echelons / Social Proof Tzahnke is to say thanks to those that have helped the project. That can be spreading the word on social media, helping out newbies on Telegram / BitcoinTalk, writing articles, translation, etc. Just link to any posts you make under Mining Social Proof on your Hadron Dashboard.
Those with higher Social Proof are activated sooner and have higher Echelon levels, which enables higher mining caps and more concurrent mining tabs. (It is optional though: we have many activated miners that have not done any social proof.)
