Bitcoin Over Airwaves: How to Send BTC with No Internet

Short-Form Step Breakdown:

1. Solar-powered ESP32 turns on

2. You sign a Bitcoin transaction (offline)

3. Transaction is sent via LoRa radio

4. Message hops through mesh of nearby devices

5. One device with internet broadcasts to Bitcoin network

6. Payment confirmed — no cell towers, no servers, no trace

Real-World Analogy:

You write a letter → strangers pass it hand to hand → someone eventually drops it in a post office mailbox.

Mesh = hand to hand

Internet node = the post office

What Makes This Powerful:

You remain anonymous.

You don’t need infrastructure.

You could be in a jungle, protest, or blackout zone… and still send Bitcoin.

Even if the only internet connected node is 20 hops away on another continent, your signal can still reach it.
