We have just wrapped up a project with the Guardian Project team exploring options for connectivity to allow for updates to software and content on the Butter Box and for communications between users of multiple Butter Boxes. We have explored two technologies: LoRA and WiFi HaLow.

Each of these has benefits and drawbacks and the choice of technology would be use case dependent.

We have not explored network or application layer protocols that would be run over these links, however the ecosystem has many options to choose from for this whether it be IP-native protocols, Iroh’s networking layer using custom transports, Willow’s distributed synchronisation protocol, or Toosheh’s content distribution and synchronisation protocol.

Until now, it has only been possible to update a Butter Box by physically replacing the USB drive with one with updated content. We are hopeful that the learnings from this project will inform integration of an interconnection technology into a future release.
