Details

BTCMesh: Bitcoin over a LoRa mesh network
  • The session starts with the fundamentals: what LoRa actually is, how a mesh network routes around missing infrastructure, and the hardware it all runs on.
  • Compare the two leading LoRa mesh protocols in active use today — Meshtastic and MeshCore — including how each one moves a message across the network and where their trade-offs lie.
  • With BTCMesh, sign a transaction completely offline, send it as chunked packets across the mesh to a relay operator with internet access, and watch it broadcast to the public Bitcoin network live, with the resulting transaction visible in the mempool within seconds.
  • Useful for anyone interested in resilient communications, financial censorship resistance, off-grid connectivity, or what a radio network without towers, SIM cards or subscriptions can do.
  • Bring a laptop and a LoRa device if you would like to try it yourself. A few spare LoRa devices will also be available on-site.
