Encrypted messaging that keeps working when the network does not.

A conversation received with no network, relayed by a nearby phone. Move your pointer: the phone follows it.

Droplet Messenger: a chat with Amina, in range over Bluetooth

Droplet Messenger explores resilient communication. Messages are end-to-end encrypted, and phones close to each other can exchange them directly over Bluetooth and local Wi-Fi, without the internet. When a recipient is offline, an encrypted copy waits on a mailbox server that cannot read it.

Objectives

  • Keep people in touch when mobile data is expensive, slow or cut.
  • Encrypt every message so that only its recipient can read it.
  • Let one account follow its owner from the phone to the browser.

Roadmap

  • Automated tests for the servers and the encryption code.
  • A separate test environment before each production release.
  • The mesh engine and the identity system as reusable modules.
