There is a website that uses the Steemit blockchain and smart contracts to ensure that you get atleast your share of upvotes!
How it works:
You upvote other Steemians who use the Steem follower platform!! And depending on the amount you spent upvoting others, your post will be displayed on the website until you make back your votes, and your contract is concluded. This way if you spend $1 upvoting others, you will get atleast $1 back for your post! This is ensured through the smart contract! :)
