Thanks again brother. Among the graduates of the basic course on Bitcoin I have a guy who is dedicated to networks. So with this suggestion and his knowledge we could make a mesh network between us and at least 1 public node in case we have to receive or send outside the network we are going to build.

Would that be the idea?

There would be no fee between us because we are all using the same node.

That happens with WoS wallets, there is no fee between them because they are all related or connected in the same network?
