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 has launched a beta project called Bitchat, a private messaging app that uses mesh networks and Bluetooth technology to facilitate communication without internet connectivity. Bitchat allows direct peer-to-peer messaging within physical proximity and features automatic message relay to extend its range. The app prioritizes user privacy by not requiring phone numbers or permanent identifiers and ensures end-to-end encryption. Dorsey emphasizes the app's independence from traditional internet infrastructure, making it resilient to outages and censorship. The project is still in its early stages, and its technical robustness remains to be evaluated.

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 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.

Jack Dorsey has launched a decentralized messaging application called Bitchat, which operates solely over Bluetooth networks without requiring internet connectivity or central servers. The app uses advanced technologies like Bluetooth mesh networks and message encryption to enable encrypted communication between nearby devices, with each device functioning as a node. Bitchat does not depend on Wi-Fi or cellular service, storing messages only on the user's device and ensuring they disappear by default. It supports group chats organized with hashtags and secured with passwords, and can forward messages to temporarily offline users. Future updates will include Wi-Fi Direct to improve network speed and capacity. Bitchat is currently in beta through TestFlight, but access is limited due to capacity constraints.

Researchers from the Technical University of Berlin conducted a study using the video game Minecraft to explore how individuals learn both independently and collaboratively in changing environments. Participants engaged in a virtual foraging task, alternating between solo and group efforts to find hidden resources. The study manipulated environments to create "patchy" and "random" settings, examining when players chose to explore alone versus follow others. Data on players' visual attention and movements allowed the researchers to develop a behavioral model predicting actions based on individual and social learning strategies. Findings indicated that adaptability—switching between learning modes based on context—was crucial for success, highlighting that individuals are capable of adjusting their strategies rather than strictly imitating others or working independently. The research suggests that personal rewards influence learning types and emphasizes the importance of flexibility in decision-making.
