Jack Dorsey, co-founder of Twitter, has launched Bitchat, a peer-to-peer messaging app that operates over Bluetooth without the need for internet or phone numbers. Currently in beta testing via Apple's TestFlight, Bitchat uses local Bluetooth mesh networks to relay messages, ensuring encrypted conversations that disappear by default. Users can create password-protected group chats and future updates may include Wi-Fi Direct support. The app is designed for use in situations with compromised internet access and does not collect user data or require accounts. A whitepaper on GitHub outlines its technical framework aimed at resisting censorship. While still in early testing, the app's effectiveness at scale is yet to be evaluated, and there are no announcements for an Android version or public launch plans.

Jack Dorsey has launched a new messaging application called Bitchat, which operates outside the conventional internet framework. Bitchat uses Bluetooth technology to send messages directly between devices, eliminating the need for phone numbers, servers, and data plans. The app allows communication over distances of up to 300 meters by relaying messages through nearby devices. Bitchat does not include usernames, chat backups, or lengthy inbox histories; messages are ephemeral, encrypted, and stored locally. The beta version was launched on Apple’s TestFlight, filling 10,000 testing slots quickly. The app currently supports small group chats with features like hashtags and password protection, and future updates may introduce WiFi Direct support. Bitchat aims to provide direct, unmediated communication, aligning with Dorsey's vision for user-centric technology.

Jack Dorsey, co-founder of Twitter and CEO of Block, has launched a messaging app called Bitchat, which enables communication without internet connectivity using Bluetooth mesh networking. Bitchat operates on a peer-to-peer basis, does not require user accounts, and ensures messages are encrypted and temporary, without interaction with a central server. Users can communicate within a 300-meter radius, and messages can be relayed to others beyond direct Bluetooth range. The app features password-protected group chats, delayed message delivery for offline users, and will support Wi-Fi Direct for improved range and speed. All messages are stored solely on users' devices and are designed to disappear over time. Bitchat is described as a decentralized, peer-to-peer messaging application resilient to network outages and censorship. The beta release quickly filled all 10,000 slots, indicating significant interest.

Jack Dorsey has introduced Bitchat, a decentralized peer-to-peer messaging application that operates on Bluetooth networks without the need for an Internet connection, phone numbers, or email addresses. It utilizes Bluetooth mesh networks for encrypted communication, allowing messages to "hop" across devices. Messages are stored only on users' devices and disappear by default, with privacy features like cover traffic, timing randomization, and ephemeral identities for user anonymity. Bitchat supports group chats identified by hashtags, which can be password-protected, and allows messages to be forwarded to offline users. Dorsey described Bitchat as a weekend project focused on exploring Bluetooth mesh networks and encryption techniques. The app is currently in beta testing via TestFlight, which has reached capacity, and there are plans to integrate WiFi Direct support to enhance its capabilities.

Jack Dorsey has introduced Bitchat, a messaging app that operates without internet connectivity by using Bluetooth technology for direct messaging. The beta version is available via TestFlight, and a white paper is accessible on GitHub. Bitchat functions as a peer-to-peer platform, leveraging Bluetooth mesh networks to allow users to exchange encrypted messages without requiring internet access, central servers, phone numbers, or email addresses. Messages can travel up to 300 meters by relaying through other devices. All messages are stored on users' devices, disappear by default, and do not pass through central servers, prioritizing user privacy and resistance to censorship. Bitchat allows for group chats called “rooms” and includes a feature for saving messages for offline delivery. Future updates will introduce WiFi Direct capabilities. Following the announcement, all 10,000 beta spots were filled.

Jack Dorsey, co-founder of Twitter and CEO of Block, has launched Bitchat, a messaging application that operates independently of the internet or mobile networks, using Bluetooth mesh networking for secure and anonymous communication. The app, currently in beta testing, does not require phone numbers, email addresses, or user accounts, allowing encrypted messages to be transmitted directly between nearby devices. Messages are end-to-end encrypted and disappear by default, with no data stored on a central server. Bitchat also features group chat rooms, mentions using @handles, and password-protected conversations. A store-and-forward mechanism allows messages to be saved and delivered later. Dorsey plans to integrate Wi-Fi Direct support to enhance communication range and speed. The whitepaper discusses potential use cases for Bitchat, including disaster response and community coordination.

Jack Dorsey, co-founder of Twitter and CEO of Block, has launched a messaging service called Bitchat, which allows smartphones to exchange encrypted messages via Bluetooth without internet connectivity. Currently in beta on Apple’s TestFlight, Bitchat creates a mesh network linking nearby devices, enabling communication even when cellular and Wi-Fi signals are weak. The app does not route traffic through company servers, collect personal information, or require accounts, and messages are stored only on users' devices and designed to disappear by default. Bitchat features group chats called “rooms,” identified by hashtags and secured with passwords, and includes a “store and forward” capability for offline users. The application aligns with Dorsey's commitment to decentralization and is intended to facilitate communication during blackouts, censorship, or surveillance. A technical paper about Bitchat is available on GitHub, and future updates will enhance connectivity through Wi-Fi Direct links.

Jack Dorsey, CEO of Twitter, has launched a new messaging app called Bitchat, which operates on a decentralized, peer-to-peer basis using Bluetooth mesh networks for communication without internet connectivity or central servers. The beta version is live on TestFlight, and a white paper is available on GitHub. Bitchat allows for ephemeral and encrypted communication between devices in close proximity, creating local Bluetooth clusters for message relaying. Certain "bridge" devices can expand the network over greater distances, and messages are stored only on devices, disappearing by default. The app supports optional group chats secured with passwords and includes store and forward functionality for offline users. Future updates may introduce WiFi Direct capabilities. Bitchat does not require accounts or data collection, making it a privacy-preserving alternative to mainstream messaging platforms.
