Identity

[decanus]

Problem

Currently in the UB.swift the node ID is based on the on the Transport. This isn't optimal as there is no verifiability that a message really originally came from a certain node. Any malicious node could change who the sender was.

Solution

Nodes should hold private keys with which they sign to ensure that they really are the original sender of a message, this means no middle node can change the original sender.
