If I understand correctly, in the event that parts of the world are without internet, signed bitcoin transactions can be moved through LoRa devices (radio) until it reaches a device that’s connected to the internet or the Bitcoin Network to broadcast the transaction?
And also, at some point in the future the Bitcoin network can operate on radio? Meaning, LoRa devices can broadcast transactions directly and operate copies of the Bitcoin blockchain?
Meshtastic is an off-grid wireless mesh communications network so it doesn’t rely on Internet or cellular connectivity. It is primarily used for text based messaging at the moment but people are looking at how Bitcoin transactions can be transmitted over it so it could be used as you suggest for sending transactions where there is no Internet or in situations where the Internet is down.
It is very slow compared to the Internet and other forms of networking so I don’t know that it could ever make up a large portion of the Bitcoin network but there are definitely possibilities to use it in some way.
you need blockchain access to make a transaction but in principle it's correct, yes
