Interesting concept but it's still not really clear, how you would secure the network with only one miner per country as example?
It is not one miner per country. This is just the current phase. Right now we are building this chapter network as the backbone of the mining network. Once we have a highly distributed backbone with engaged people, the mining will be open to anyone to participate anonymously. In that way bad actors will be outnumbered by chapter miners. I understand it is difficult to understand if you don't know the full plan.
