Jack Dorsey just released a Bluetooth messaging app that doesn’t need the internet

Jack Dorsey has unveiled a groundbreaking decentralized messaging application, Bitchat, which operates exclusively over Bluetooth networks, as reported by CNBC. This innovative platform eliminates the need for internet connectivity, functioning without any central servers.

Exploring the Technology Behind Bitchat

Dorsey describes Bitchat as an experiment in various advanced technologies, including Bluetooth mesh networks, relays, store and forward models, and message encryption. The app facilitates encrypted communication between nearby devices, allowing messages to be transmitted directly from one gadget to another. Each device acts as a node, gradually expanding the network.

One of the standout features of Bitchat is its resilience; it does not rely on Wi-Fi or cellular service, making it particularly useful in situations where internet access is restricted. Messages are stored solely on the user’s device, disappearing by default without ever connecting to centralized infrastructure. This technology echoes its previous applications during the Hong Kong protests in 2019, where it played a crucial role in maintaining communication.

Features and Future Developments

Bitchat supports group chats that can be organized with hashtags and secured with passwords. Additionally, it has the capability to forward messages to users who may be temporarily offline. Future updates are expected to introduce Wi-Fi Direct, enhancing the speed and capacity of the network.

Dorsey has consistently championed decentralized communication platforms, as evidenced by the open-source framework of Bluesky, which emphasizes user autonomy. Currently, Bitchat is available in beta through TestFlight, although access is limited as the platform has reached its capacity.
