"Jack Dorsey's new app, Bitchat, debuts on the App Store; here's a rundown of the essential details"
In an exciting development for iPhone users, Jack Dorsey, co-founder of Twitter, has launched a new messaging app called Bitchat. This innovative app allows for encrypted, peer-to-peer messaging without the need for Wi-Fi, mobile data, or centralized servers.
Bitchat functions through a decentralized peer-to-peer mesh network using Bluetooth Low Energy (BLE). This means that devices can connect directly and relay messages without any internet or cellular network. When a user sends a message, it is broken into encrypted packets and transmitted over Bluetooth to nearby devices running Bitchat. These devices then forward the message to others in the network until it reaches the intended recipient, even if that recipient is beyond the direct Bluetooth range.
Each device running Bitchat acts both as a client (sending/receiving messages) and a server (relaying messages for others), forming a mesh topology where messages travel indirectly through multiple intermediate nodes. Messages are encrypted end-to-end using protocols like Noise, ensuring privacy and security without the need for phone numbers, usernames, or cloud storage. Messages are typically deleted after delivery, unless stored temporarily on devices (up to around 12 hours) to support delivery when recipients are offline and rejoin the network later.
The app is especially useful in scenarios where traditional networks are unavailable or congested, such as remote areas, disaster zones, large public events, or situations with internet censorship. Users must have Bluetooth enabled and the app installed to participate in the network, and communication only occurs between devices with the app. This infrastructure frees users from dependence on cellular towers, Wi-Fi, or centralized servers, providing resilient and private messaging purely through proximity-based device collaboration.

It is important to note that Bitchat has not undergone external security review, and a warning has been added to its GitHub page by Jack Dorsey stating that the software may contain vulnerabilities. Users are advised against relying on its security until it has been reviewed.
This groundbreaking app is just one example of the innovative technology being developed in the tech industry. As we continue to push the boundaries of what is possible, we can look forward to even more exciting advancements in the future.
