SourceCred ERC-20 Token and/or DAO

Also related is CreDAO (SourceCred + Aragon DAOs), which could create a nice synergy between earning Cred and minting tokens on the Aragon DAO. Since Aragon is a modular platform this could be combined with the Aragon Fundraising bonding curve mechanism being explored in this Initiative as well. Could be great for SourceCred, MetaGame, Aragon, and lots of other people too. Then there would be an end-to-end system that allows people to earn reputation and rewards for contributions, claim those rewards on Ethereum, all while also allowing people to contribute to the project by buying Grain on Ethereum too.
