You have to trust that the person/node will do the task otherwise there is no point in delegating in the first place.
You continue to ignore information which has already been stated. I have emphasized upthread that the nodes are fungible, replaceable, and unable to monopolize their function. A node that continuously doesn't do its function will simply have removed itself from the network giving way to the other nodes which are doing their function.
I think you ought to just wait until I publish the entire white paper, so the whole thing can make sense to you.
Perhaps you should publish all of the available information (without revealing your entire system) to the OP as opposed to cherry picking what you want to disclose and then doing a dance as people's questions come into this thread.
One thing I despise is a moving target in a discussion.
