But who&#x27;s going to abuse it? Why would it shut down indefinitely? This is a group of people or entities that has decided to do this. Presumably they all feel it&#x27;s in their interests to make it work. Same as with any mutual agreement of this kind, if there&#x27;s some kind of a falling-out, they&#x27;ll probably just figure it out somehow.<p>(As for invalid blocks - in the absence of a bug in the code that runs the system, all validators will say no to the invalid block(s), so there&#x27;s no disagreement, and things carry on.)
