Just want to solve it the usual way, by allowing everyone to know all the txs that ever happened on the time chain aka running a node. Just changing the communication layer. As mesh are much slower this would maybe require: - in certain areas of the world to wait 144 block instead of the 6 recommended or more (or less) to be sure that a tx is settled - to initially trust someone with internet access who could provide a recent snapshot of the blockchain as no IBD can be done through mesh network I assume
