What is Jack Dorsey’s bitch?
Jack Dorsey’s new app could revolutionize offline communication. The founder of Twitter and Block CEOs has launched the pilot for Bitchat, an innovative new messaging app that works perfectly without an internet connection.
What was originally a Dorsey weekend project has quickly evolved into a compelling proof of concept. It could provide truly decentralized censorship-bearing communication, all of which are turning their heads in the world of technology and worrying about the government.
Bitchat was released in beta on July 7, 2025, maximizing 10,000 TestFlight slots within hours. We will immediately show interest in such offline communication solutions.
However, this app is more than just a technical experiment. It marks a step towards a future where communication may exist, even when traditional infrastructure fails or faces censorship. In an increasingly surveillanced digital world, censorship-resistant communication tools are piqued the attention of many users.
How does the Bitchat offline messaging app work?
Bitchat runs on a distributed peer-to-peer messaging system running on Bluetooth Low Energy (BLE) mesh networks. This means that you don’t need a server, internet, phone number, or centralized infrastructure.
Simply put, it runs on a variety of principles compared to traditional messaging apps like WhatsApp. Remove the need for cell towers and WiFi networks and create a distributed mesh for Bluetooth instead.
As shown in the image above, the mesh network uses BLE to relay messages across nodes within 30 meters. Alice’s message to Dave reaches her destination via an intermediate device (Bob and Carol).
All devices running bitchat act as both the user and the server’s messaging client. This creates a mesh topology. How does this work:
When you send a message, you will not be transported to a distant server on your mobile phone or internet network. Hop directly between the device and nearby Bitchat users. It’s like a high-tech Chinese whisper. This message hopping technique requires a direct Bluetooth range between devices ranging from about 30 to 100 meters. Using the Store and Forward system, messages can move beyond this Bluetooth range. For example, if the recipient is temporarily offline, it caches the message, saves it to a nearby device, and then reconnects it to the mesh and delivers it to the recipient.
Key Technical Components
There are several important technical components that enable Bitchat to work this peer-to-peer.
Peer-to-peer architecture: There is no single point of failure when each device acts as both a sender and a relay node. Relying on hundreds or thousands of nodes results in decentralization that cannot defeat the network due to a single attack or outage. Message Hopping: Data packets can jump up to 7 times through a network device. Each device adds routing information to build an efficient path. Therefore, data is passed across multiple devices, but only the recipient and sender can read the message. Persistent Identifier: A random peer ID is generated for each session to protect the privacy of the user. So, every time you open the Bitchat app, it will provide your device with an ID. There are no permanent phone numbers or emails.
Did you know? The global messaging security market is projected to jump from $8.56 billion in 2024 to $204.1 billion. In response to regulatory oversight and rising cyber threats, more users and organizations are demanding privacy-first solutions.
How to use the Bitchat Decentralized Messaging App
Currently, Bitchat is not the official app for the iOS or Android store. This beta version has already reached its maximum capacity, but it can be used as a beta version of iOS devices using Apple’s TestFlight, the platform used to test apps before they are released on the official app store.
The GitHub community has also created an unofficial Android version that can be used. However, Android users will need to sideload the app that involves downloading the APK file from GitHub and installing unknown apps from the browser.
Getting started with Bitchat is refreshingly simple. There is no troublesome phone number, account creation, or personal information. Once loaded, the Bitchat application will start looking for peers near the Bluetooth mesh. You will automatically receive a nickname such as “Anon1234”. This can be customized later. For those who have used Classic Chat Rooms in the past, they are familiar with the IRC style command interface. Once you’ve connected to a nearby user, you can start chatting with other users, even if you’re in an area without cell coverage or internet. Messages are relayed over a Bluetooth mesh network.
Privacy First Design also has an emergency wipe feature that allows you to triple tap on a triple tap to instantly clear all local data.

Explained the use case for bitch
Bitchat is more than just a gimmick messaging app or is trying to avoid monitoring. Dorsey outlines several important use cases, including:
Disaster adjustment
In scenarios where cell towers fail, such as Hurricane Katrina in 2005, Bluetooth-style mesh networks could potentially be able to maintain community and emergency services connectivity during a disaster. The value of mesh networks can be important, especially for emergency responders, when traditional networks collapse.
Event Overflow
When there is a large gathering of festivals or protests, mobile networks can be overwhelming in places with poor coverage. Mesh expansion helps to extend the scope of communication and effectively extend the network across the event space. Participants will be able to form topic-based channels for messaging without internet access and provide important presentations for group coordination.
Checkpoint synchronization
In places with censored or intermittent internet, users can continue to chat and share information using Bluetooth, even if they only have a short window of connection to the internet. Regular synchronization also allows any device in the mesh to temporarily regain internet access at checkpoints like WiFi hotspots, syncing specific channels or messages with a wider network.
Cross Community Bridge
Separate communities in geographically relevant regions, such as villages, were able to communicate without relying on centralized infrastructure. It can provide coordination, resource sharing and collective decision-making where it is not reachable via the Internet. This system allows you to enter and exit mesh networks in nearby communities, but at larger distances, messages are usually cached on the device for 12 hours, making it awkward for long travel times.
Did you know? A similar Bluetooth messaging app called Bridgefy saw 4,000% use spikes during Hong Kong protests, showing the power of offline, peer-to-peer messaging to protect against censorship.
The evolution of mesh networks and decentralized messages
Bitchat could trigger a wider movement to incorporate mesh networking technology. While major tech companies have already invested in mesh solutions such as Google’s Nest devices with mesh networking capabilities, Starlink uses satellite constellations to create space-based mesh networks.
The direct device-to-device communication provided by Bitchat aims to minimize reliance on communication providers and increase resilience during outages, censorship or disaster scenarios. During politically unstable regions or Internet power outages, such platforms can become important tools for free expression and grassroots organizations.
For regulators, it raises some important points. Without central authority and full encryption, it becomes difficult for law enforcement. As you might have seen in privacy-centric messaging apps like Telegram in the past, law enforcement has struggled to track criminal activity with a fully private, encrypted messaging system. Fast adoption of apps suggests there is a strong demand for decentralized communication tools.
However, as users become more aware of data ownership and monitoring, decentralized messaging taps on the desire for increased autonomy. These systems are difficult to shut down or censor because there is no single point of failure or control. As mesh networking matures, shifts may appear not only in how messages move, but also in how people perceive trust, privacy and control in digital interaction.
