Bounty is a Ethereum based Q&A platform where you can get rewarded in Eth for your answers. You can propose a question (challenge) with Eth attached as the bounty as well as a time duration on when the challenge ends. Others can then answer your question by submitting responses (submissions), and everyone is free to vote on submissions. When time runs out, anyone can trigger a function to settle payments algorithmically based on who received the most votes. Enjoy!
