Jack Dorsey unveils a new offline-functional application, dubbed Bitchat.
Jack Dorsey, the co-founder of Twitter and CEO of Block Inc., has launched a new messaging app called Bitchat. This innovative app, released in July 2025, utilizes Bluetooth Low Energy (BLE) mesh networks to enable encrypted peer-to-peer communication without the need for an internet or mobile network connection[1][5].
How Bitchat Works
Bitchat's architecture relies on BLE mesh technology, where messages hop between nearby devices that act as nodes, creating dynamic, self-healing, and resilient communication pathways even when traditional infrastructure is unavailable[1][2]. Devices on Bitchat communicate directly with each other using this technology, making it possible for messages to be transmitted over a range of 300 meters or more[1].
Privacy and Security
The app's core privacy features include end-to-end encryption by default, no requirement for user accounts, and zero metadata collection[2][5]. This design ensures that neither content nor usage patterns are stored or accessible to intermediaries, providing operational anonymity for users[1][2]. Messages on Bitchat are protected using high-security standards and are deleted after delivery, unless users explicitly choose to save them[1].
Potential Impact
The potential impact of Bitchat is significant, particularly in scenarios where communication infrastructure is compromised or tightly controlled. It is tailored for use in natural disaster zones, protest environments, surveillance states, and regions with government-imposed network blackouts, allowing users to maintain secure, infrastructure-free communication when it is most needed[2][5].
Community Development and Adaptation
Bitchat is released into the public domain to encourage community development and adaptation. There are plans to integrate with decentralized internet-based systems like Nostr, which would combine local-first BLE privacy with optional internet routing, potentially extending its use beyond Bluetooth range without sacrificing censorship resistance[2].
A Step Towards Digital Autonomy
Initiatives like Bitchat pave the way towards digital autonomy in the context of growing questions about content moderation, user tracking, and algorithm manipulation in social media. Bitchat prioritizes direct, group, and decentralized conversation, positioning itself as a powerful tool for censorship-resistant, resilient communication in offline or restricted environments[1][2][5].
