Concept of steemit
User accounts can upvote posts and comments similar to other blogging websites or social news websites like Reddit, and the authors who get upvoted can receive a monetary reward in a cryptocurrency token named STEEM and US dollar-pegged tokens called Steem Dollars. People are also rewarded for curating (discovering) popular content. Curating involves voting comments and post submissions. Vote strength and curation rewards are influenced by the amount of STEEM Power held by the voter.[6][8]
Steemit includes third-party applications, such as d.tube, a decentralized video platform based on the InterPlanetary File System (IPFS) protocol. D.tube is similar to YouTube, but without advertisements, instead uses the built-in Steem currency which gets awarded by users upvoting videos.[9]
