Twitter co-founder Jack Dorsey launches a messaging app ‘Bitchat’ that works without internet

Jack Dorsey is developing a messaging application called Bitchat that uses Bluetooth Low Energy (BLE) mesh technology for peer-to-peer communication. The app allows users to send messages over distances greater than 300 meters without the need for mobile data or Wi-Fi. Currently in beta on Apple’s TestFlight, Bitchat emphasizes secure and decentralized communication, sending short-lived, encrypted messages that relay between nearby devices without a central server. It does not require a phone number, email address, or user account, making it resilient against censorship and network outages. Bitchat aligns with Dorsey’s support for decentralized platforms and is inspired by Bluetooth tools used during the 2019 Hong Kong demonstrations.

Jack Dorsey Builds Bitchat, A Bluetooth Messaging App That Doesn’t Need Internet, Phone Numbers

Jack Dorsey has launched a messaging app called Bitchat, which operates without an internet connection by using a Bluetooth mesh network. The app allows devices to communicate directly, facilitating message exchanges without mobile data or centralized servers. Currently in beta testing on Apple TestFlight, Bitchat aims for peer-to-peer communication off the grid and incorporates "store and forward" technology for message delivery. It allows users to communicate anonymously without the need for accounts or personal information, making it suitable for privacy-conscious individuals, activists, and those in areas with restricted internet access. However, Bitchat has limitations, including range restrictions due to Bluetooth connectivity, support for only plain text messages, and potential increased battery consumption. The app is still in development and not fully polished.

Bitchat Is a New Messaging App Which Works Without Phone Numbers

Jack Dorsey has introduced Bitchat, a decentralized messaging application that operates using Bluetooth Low Energy (BLE) mesh networks for peer-to-peer messaging without traditional internet connectivity. Bitchat features end-to-end encryption for security, operates independently of the internet, and allows users to send messages over a range of more than 300 meters. Each device functions as both a client and server, enabling multi-hop message delivery. Messages are ephemeral by default, with a caching feature for recipients who are temporarily unavailable. Regular messages last 12 hours, while favorites are retained indefinitely. Bitchat does not require phone numbers or email addresses, enhancing user privacy, and includes features such as mentions and topic-based discussion rooms that can be password-protected. The app is currently in beta testing via Apple's TestFlight program.
