Jack Dorsey, the visionary behind Twitter and the current CEO of Block, has taken a bold step into the realm of communication with the launch of his latest creation, Bitchat Mesh, or simply Bitchat. Released on July 28 through Apple’s App Store, this open-source messaging app was initially introduced as a “weekend project” on X, formerly known as Twitter, earlier in the month. However, potential users should temper their expectations; Bitchat is not your typical polished messaging platform.
The app features a minimalist design and operates on a unique premise: it utilizes Bluetooth for data transmission rather than relying on traditional internet connections, Wi-Fi, or cellular data. While the open-source nature of Bitchat allows for scrutiny of its code, users are advised to exercise caution regarding its security until a third-party audit is conducted.
How do I connect with people?
In a departure from conventional messaging apps, Bitchat does not leverage your contacts or phone numbers for connectivity. Instead, it establishes a Bluetooth mesh network, allowing users to connect with nearby devices. This innovative approach means that as you connect with others in your vicinity, your network expands, creating a web of communication that can extend beyond the immediate range of a single Bluetooth signal.
The app’s website succinctly explains, “Bitchat creates ad-hoc communication networks using only the devices present in physical proximity.” Each device acts as both a client and a server, automatically discovering peers and relaying messages across multiple hops. While this design fosters a potentially expansive network, it also means that communication is limited to those within the same network. Thus, while you may not be able to message someone across the globe, a sufficiently large user base could enable communication over considerable distances.
Upon opening Bitchat, users will notice a counter in the top right corner indicating the number of devices connected to their network. For instance, one user might find their count at one, representing a connection to another device they own. Tapping this number reveals a menu displaying connected users, allowing for private messaging away from the main chat. Messages sent in the main chat are visible to everyone in the network, making private conversations more suitable for direct messaging.
Currently, Bitchat appears to be a practical tool for maintaining contact at events like music festivals or parties. However, as the user base grows, its utility could extend into a wider array of scenarios.
Does Bitchat have any other messaging features?
While Bitchat is relatively straightforward, it does offer a few additional features beyond basic messaging. Users can send private messages, block others, or engage in playful interactions by sending virtual “hugs” or “slaps.” These playful gestures serve as lighthearted notifications within the chat, with the slap option humorously described as “slapping them around a bit with a trout.”
Transparency is also a key feature; if a user takes a screenshot of a conversation, an in-chat notification will alert others, fostering an environment of openness. Overall, Bitchat remains a simple, no-frills messaging app designed for direct communication.
How secure is the app?
As an open-source application, Bitchat allows for public inspection of its code, which is essential for identifying vulnerabilities. Recently, a user reported a security concern regarding authentication, prompting Dorsey to implement the Noise Protocol Framework. This framework aims to provide end-to-end encrypted communication that is secure, private, and resistant to censorship.
However, Dorsey has also issued a cautionary note on GitHub, stating, “This software has not received external security review and may contain vulnerabilities and does not necessarily meet its stated security goals.” He advises against using the app for production purposes until it undergoes a thorough external review. While the open-source nature of Bitchat is promising, a third-party security audit would significantly enhance user confidence in its safety.
In summary, while Bitchat offers a novel approach to messaging, users should remain vigilant regarding its security until a comprehensive evaluation is completed. For those interested in privacy and security, exploring other encrypted messaging options and VPN services may also be worthwhile.
