RED LIBERTAD, a Bluetooth mesh for Cuba

Field notes

The homepage describes a store-and-forward model in which nearby Android phones detect one another over Bluetooth and relay messages across multiple hops until each message expires. It specifies Android 7.0+, local aliases instead of phone numbers or accounts, and direct APK distribution rather than Google Play. Examples include convocations, voice notes, photos, and urgent alerts. The site also links to security material and checksum verification, although the supplied evidence does not independently establish the APK’s security or operational reliability.
