bro, they've described quite clearly in their first post. if you need more, you can read the white paper. they are developing a reviews platform based on blockchain for tor network and business there. you get rewarded for a couple of tokens for leaving a review and then can exchange it for real money. I guess the description if one of the clearest on this forum.

anyway I have few questions to the developers too. besides the bounty program which I asked about above, I wonder how EXACTLY you will recognize my review? I mean what are the mechanics of this process. will you develop a special algorithm for analyzing the text of review or what? or you will use an existing algorithm for this? if is one that already exists, how will you resist spam attacks and people wanting to get easy coins for useless review? thanks.
