Radio is the cockroach of communication media — it survives everything.

My Bitcoiner friends living in Portugal told me that when nothing was working yesterday (internet, power, TV), the battery-powered radio was how the Portuguese stayed informed.

Decentralized, local, and resilient to blackouts.

Bitcoiners need to develop ways to transact via radio or ham radio when electricity or internet is down.

I imagine the path would be some form of ecash to sign off-chain transactions via radio while the internet is unstable.

Once the internet comes back, the ecash could be broadcast on-chain.

I’m no expert, I think this is NVKs wheelhouse

theoretically it’s possible to encode or compress token strings and then transmit via digital ham radio modes like PSK31, FT8, or JS8Call but it’s quite an undertaking and also generally illegal I believe as Ham radio cannot be used for encrypted or commercial communication

that hasn’t stopped hobbyists sending raw Bitcoin transactions via JS8Call. Similarly check out Samourai’s TxTenna using GoTenna and LoRa based mesh radios like Locha mesh developed by Venezuelan bitcoiners
