Secure voting resolvement with the Oracle of reality.eth
After the voting is over (normally 12h - 24h) and the community made it's decision, the proposal will get added to the DAO module which will trigger a question on https://reality.eth.link/ and a 24h cooldown to find the solution to the question. Everyone will be able to answer the question and set a bond. The concept is that if somebody is posting a wrong answer, you can keep pushing them to post a higher bond until their bond would be greater than the amount you paid for arbitration. The limit is that somebody (not necessarily the first person to answer) has to be able to put up enough capital (in the expectation of making a profit).
This crowd-sourced verification has been widely used on Ethereum and is extremely succesful and secure.
