Hi. OP here.
The article is part of the Freedom Layer project, where we describe the research of creating a scalable and secure mesh network. (It is currently still an open problem, at least by what we know).
The first things we have decided to do is to document known stuff. Then we move on to documenting our research. We will try to make it as down to earth as possible, though later articles might get more complicated. Some new results are also going to be discussed.
