How about some simple, plain English instructions on how to set up the nodes? Inexpensive nodes. That should be possible now, shouldn't it?

These instructions may already be out there somewhere. If so, can anybody share the link? Thanks!

As for the business logic on the second layer ... Is there a possibility to write this logic supported with a set of tools/libraries? Or is everybody on her/his own when starting the layer 2 coding journey?

Thanks again for some input.

Ps: I agree that layer 1 should be slim and robust.
