This is an interesting concept but it could have a dark side. What is to stop some bad actor from putting out a contract on hacking some organization or person. What if some creep wants the address of a celebrity or other person to kidnap or stalk them so he puts out a contract on that info and a hacker with an incentive delivers on it. This could be a good tool for a more open honest society but we have to realize these things might happen and plan accordingly. 10/10 in the first day someone will put a contract on Trump's tax returns.
