keeping a peer-to-peer ledger using two solid pods

one way of doing this would be to let each party host their own outbox, and either they subscribe to each other's live updates, or they post notifications to the other's inbox.
trouble is, message 01could be changed after they have been sent, so either keep two signatures on each timestamped ledger entry, and link to the previous entry so entries can not be deleted.

or you could keep it simple and accept that the other party could cheat, just make sure you detect if they do, so you keep a copy of the current balance, and that's it.
