@ Snail2, Indeed i get your point.

PS: Locked the topic, since i didn't find any other way of removing it.

A full mesh architecture, like your first drawing is more resilient and more distributed, but less manageable. A hierarchical design makes easier to implement some advanced functions but it's more centralized, therefore less resilient than the mesh. I think the appropriate design depends on the planned functionality of your coin.
