If you can get a mesh net up and LN async payments or something like greenlight or ecash boy then you've got quite the product on your hands to take it through some of the toughest places to get money and transact freely and cheaply
Great write up. I could see something like this working at a marketplace (or major conference with terrible reception). I don't think total offline would work well at all, some people will need to be online. But this could be on some of the merchants with a data plan. The ones with internet could be the hub(s) and the users and other merchants could have their channels with the hub(s). Then routing could take place.
It's probably only worth it if users at the end of the day could go home or get internet access later to verify the chain and channel state. Otherwise the hassle would be too much, it might as well be custodial.
Really interesting… certainly within closed local environments. Not sure on the offline scalability (ie a widespread disaster relief situation / multi-national refugee camp etc) but will watch with interest.

Not exactly mesh, but they offer LoRaWAN and 5G hotspots designed for decentralised wireless infrastructure (long-fi). You can mine token Helium (Solana blockchain) while you cover your region (town according to them) with long-fi. https://www.linxdot.com/
