Tether open-source project adds Bluetooth messaging for iPhone and Linux

Tether’s open-source project has added Bluetooth messaging support for iPhone and Linux, extending cross-platform connectivity beyond its existing app environments. The integration lets users exchange messages directly over Bluetooth, reducing reliance on internet connectivity while raising privacy questions around proximity-based communication. The update matters because it broadens Tether’s open-source tooling at the device level, not just in token settlement, and could improve resilience where mobile networks or Wi-Fi are unreliable. What to watch next is adoption across iOS and Linux clients and whether privacy safeguards, such as encryption and peer discovery controls, are tightened in subsequent releases.
