bitchat

Overview

• Bitchat is a fully decentralized, peer‑to‑peer messaging application that operates exclusively over Bluetooth mesh networks.

• Because it does not rely on cellular data or Wi‑Fi, users can communicate with anyone in physical proximity even when the internet is censored, congested, or simply unavailable.

Core Functionality

• Instant local chat – Send text, voice notes, and small files to nearby devices in real time.

• Mesh routing – Messages hop from one Bluetooth‑enabled device to the next, extending the reach beyond direct line‑of‑sight and covering entire neighborhoods or towns.

• Location‑based channels – Join or create channels tied to a specific area (neighbourhood, city, province, region) to discuss local events, share alerts, or organize meet‑ups.

Privacy & Security

• No registration, no phone‑number requirement, and no personal data collection.

• End‑to‑end encryption safeguards every conversation from eavesdropping.

• The app does not embed tracking scripts or serve advertisements, ensuring a clean, distraction‑free experience.

Community Features

• Public notes – Drop a short text note at any geographic coordinate; anyone who later passes that spot can read it.

• Channel moderation – Community members can set simple rules for their local channels, helping keep discussions relevant and respectful.

• Peer reputation – Users can flag abusive behavior, which is recorded locally and shared across the mesh to discourage misconduct.

Use Cases

• Emergency communication when cellular networks fail.

• Organizing neighborhood initiatives, such as clean‑ups or local markets.

• Sharing time‑sensitive information during protests or natural disasters without exposing participants to surveillance.

Open Source & Availability

• The source code is released under a permissive open‑source license, allowing anyone to audit, modify, or contribute.

• Available for free on major mobile platforms; installation requires only a single download, after which the app is ready to use.

FAQ

Q: Do I need to create an account or provide personal information to use Bitchat?

A: No. Bitchat is designed for anonymity from the start. You can launch the app, grant the required Bluetooth permissions, and begin chatting without ever supplying a phone number, email address, or any other personal identifier. The app never stores or transmits personal data to a central server.

Q: Is my conversation really private?

A: Yes. Every message, voice note, and file is encrypted end‑to‑end using modern cryptographic primitives before it ever leaves your device. Only the intended recipients hold the keys needed to decrypt the content, so even if a rogue node intercepts a packet, the payload remains unreadable.

Q: Can I still send pictures, videos, or larger files?

A: Bitchat supports small attachments such as images, short video clips, and voice recordings, but the mesh is optimized for low‑bandwidth traffic. Large files may need to be broken into smaller chunks, and delivery speed will depend on the density of nearby devices. For very large media, it’s best to use a conventional internet‑based service once you have connectivity.
