Bitchat is a decentralized messaging application using a Bluetooth mesh network, operating independently of the internet.
This application encrypts messages end-to-end, does not store data on a centralized server, and maximizes user privacy by not requiring a phone number or email.
MAIN CONTENT
Bitchat operates over a BLE mesh network, independent of the internet, ensuring continuous communication when the connection is lost.
The application protects privacy through end-to-end encryption, does not store central data, and does not disclose metadata.
The smart messaging mechanism helps anonymize the identities of the sender and receiver, resists censorship, and protects information safety in difficult situations.
What is Bitchat and how was the idea developed?
Bitchat was developed by Jack Dorsey, co-founder of Twitter, as a personal project to learn about Bluetooth mesh networks and messaging encryption models. The app was put on Apple's TestFlight for users to test before the official launch.
Jack Dorsey has stated that this project aims to create a completely decentralized messaging platform, independent of traditional Internet infrastructure, contributing to enhancing user privacy.
How does Bitchat work without needing the internet?
Bitchat operates thanks to a Bluetooth Low Energy (BLE) mesh network, creating groups of devices within about 30 meters. Each device acts as both a client and a server, allowing messages to be continuously forwarded between groups until they reach the intended recipient.
This mechanism helps the application maintain communication in cases where the internet is turned off or controlled, suitable for emergency situations, protests, or natural disasters.
Bitchat uses Bluetooth mesh data transmission network models, along with end-to-end encryption to enhance security and is independent of existing internet networks.

How does Bitchat protect user privacy?
The application randomly inserts fake messages within 30–120 seconds and delays the transmission of real messages by 50–500 milliseconds, making it difficult to distinguish or analyze the timing to locate users.
Messages are only stored on devices for 12 hours for regular friends and indefinitely for close friends. This helps mitigate the risk of data leaks when devices are accessed without authorization.
How is Bitchat different from popular messaging apps today?
Unlike WhatsApp, Telegram, or Messenger, Bitchat does not store data on a centralized server and does not require any account linked to a phone number or email. Users are completely protected from personal information and metadata leaks.
Notably, the app does not disclose who the sender or receiver is, only including forwarding process data in the form of TTL and message ID to ensure correct forwarding.
In an era where personal data is exploited, Bitchat offers a decentralized, censorship-resistant messaging solution that protects privacy through Bluetooth mesh technology.

What are the practical applications of Bitchat in difficult situations?
Bitchat is designed to maintain secure communication when the internet is congested or blocked, such as during protests or natural disasters. This technology contributes to protecting freedom of speech and ensuring uninterrupted information.
With practical experience and the development of Web5, Jack Dorsey emphasizes that Bitchat is an important step towards promoting a decentralized ecosystem, aimed at an open and transparent Internet future.
