About this app

Welcome to BChat, the ultimate decentralized mesh messaging application designed from the ground up to protect your privacy and ensure your communications remain yours.

Unlike traditional messaging apps that route your private data through centralized company servers, BChat operates entirely on a decentralized mesh network. By utilizing cutting-edge Bluetooth Low Energy (BLE) technology and decentralized protocols, BChat allows you to communicate directly with peers around you—even completely off the grid.

🌐 100% DECENTRALIZED MESH NETWORK Your messages never touch a central server. BChat builds a local, self-healing network by hopping messages securely from device to device. Whether you are at a crowded festival, in a remote area with no cell service, or simply value true digital autonomy, BChat keeps you connected.

🔒 UNCOMPROMISING PRIVACY & ENCRYPTION Security is not an option; it's the foundation. Every direct message, file, and voice note sent over BChat is secured using state-of-the-art cryptographic protocols (Ed25519 signing and X25519 key agreements). Your identity is a cryptographic public key, meaning there are no phone numbers, emails, or personal data required to register.

👥 PRIVATE GROUP CHATS & CHANNELS Create secure, password-protected group chats for your friends, team, or community. Only invited members with the cryptographic group password can decrypt and read the group's communication. Easily invite verified contacts to your groups with a single tap.

📍 GEOHASH DISCOVERY & LOCATION NOTES Discover the world around you privately. Drop encrypted "Location Notes" on a map for others to find, or tune into specific geographic zones (Geohashes) to see localized public broadcasts without revealing your exact GPS coordinates to the network.

📡 OFF-THE-GRID CAPABILITIES No internet? No cell towers? No problem. By leveraging BLE (Bluetooth Low Energy), BChat devices can discover and route messages to each other locally. This makes BChat a critical tool in emergencies, natural disasters, or remote off-grid adventures.

📷 SECURE MEDIA SHARING Go beyond text. Seamlessly and securely share high-quality images and crystal-clear voice notes directly over the decentralized network. Media is chunked, encrypted, and reassembled flawlessly on the recipient's device.

✅ CONTACT VERIFICATION (QR SCANS) Never fall victim to impersonation. BChat includes built-in Identity Verification. Simply scan a friend's personal QR code in person to cryptographically verify their device footprint forever.
