BitLanders works by calculating your social engagement into a 'BuzzScore.' The BuzzScore is a competitive ranking from 0 to 100 that reflects your ability to involve users on your posts, blogs, videos, pictures, content, you name it. This takes into account how many people subscribe to your content, 'buzz' (which is like a facebook 'like') your content as well as comment.
After your BuzzScore is calculated at the end of every day, you are given a certain amount of Bitcoin as reflected by your BuzzScore and the current Bitcoin price. This money comes from a shared advertisement model. (At the moment, BitLanders does not have any ads; they are anticipating returning to advertisements with a native advertisement model as well.)
