This is what spurred my interest. My Lilygo stopped working, so I'm in the process of getting a better device. @kepford is way ahead of me on this. I would like his input.
I'm curious about the technical feasibility. I've not done a deep dive at all, but just from an online search I see that Lora radios transmits data at 0.3 to 11 kbps, whereas Bitcoin produces a 4MB(=32,000 kb) block every 10 minutes.
At 11 kbps (0.001375 MB/s) it would take 2,910 seconds (48 minutes) to transmit one block's worth of data, so these Lora nodes wouldn't be able to keep up with the chain, not to mention initial sync.
Does this comport with your understanding, or am I missing something here?

right so you're not shifting the blockchain completely to radio. You're simply relaying the transaction from node (not a BTC node, a darkwire node) in a mesh network. So you're just sending the transaction hex to be pushed to the blockchain by an exit node (a darkwire node connected to the internet).
This isn't made for the average bitcoiner, but rather for people living in areas where the government simply kills the electricity or the internet (censorship prone areas say like Rafah or Tibet).

Cool, I think this is a really noble idea and I'm just trying to wrap my head around the details.
So the idea is the Lora device would still be communicating with an internet-connected node over the airwaves.

yep, just one node (darkwire) needs to be connected to the internet, each darkwire node has a range of 10km with direct LoS. and 3-5kms in realistic conditions (cities or forests).
it's a wip progress but the base project works and you can watch the youtube video to see it working. I plan on adding nostr support to it as well.

That's great. I'll definitely be following this project with interest.
