This is remarkably light on details.. How is identity validated when the central server is offline? How can one build routes in case of intermittent point-to-point connections?<p>On the other hand, FAQ says:<p>> At the core of both our NewNode messaging app as well as the NewNode VPN is the open-source NewNode protocol. It’s this protocol that automatically detects the optimal path for your data. If there is no wifi connection, NewNode will route your traffic through a network of connected devices.<p>> As long as one of the peer devices down the line has access to a functional mobile network, your device will too. This strategy bypasses the limited central server of typical messenger apps and enables higher levels of connectivity.<p>so this kinda sounds like if there are no "functional mobile network" anywhere (say there is a wide-area outage), then this won't work at all?
