Questions & Answers

As answered by people managing KeepCalling and Bit-Chat.xyz.

What makes your product unique?

Bit-Chat.xyz's answer:

Completely Offline: No Wi-Fi, SIM card, or any servers required. All messages are relayed between devices through multi-hop Bluetooth Low Energy (BLE) mesh networking.

End-to-End Encryption + Perfect Forward Secrecy: Temporary key pairs are generated on each startup, with ChaCha20-Poly1305 encryption and X25519 handshake, ensuring messages cannot be eavesdropped on or replayed by third parties.

Anonymous and Lightweight: No account system, no phone or email registration, and no persistent identity. The application is small in size, runs efficiently, and has extremely low battery and bandwidth consumption.

Open Source Transparency: The protocol and client code are fully open source, allowing anyone to audit, deploy, or further develop them.

Why should a person choose your product over its competitors?

Bit-Chat.xyz's answer:

True Decentralization: Unlike Briar, Bridgefy, etc., which still rely on certain servers or supporting services, BitChats can be deployed with "zero infrastructure."

Full Anonymity: No registration is required; it's ready to use upon launch. Keys reside temporarily in memory and are discarded after use.

Strong Fault Tolerance: Multi-hop routing and store-and-forward automatically bypass interrupted nodes, making the network more stable.

Cross-Platform Consistency: iOS/Android/macOS CLI all support the same protocol stack, allowing seamless message transfer between different systems.

How would you describe the primary audience of your product?

Bit-Chat.xyz's answer:

Individuals and organizations with a strong emphasis on privacy and security (journalists, human rights activists, NGOs).

Users in scenarios requiring offline communication (outdoor adventurers, disaster relief teams, music festival/exhibition attendees).

Tech-driven communities (open-source enthusiasts, decentralized technology researchers, geek gamers).

What's the story behind your product?

Bit-Chat.xyz's answer:

In July 2025, Jack Dorsey personally experienced the fragility of traditional communication during a blackout drill, which sparked the idea of "staying connected even in an off-grid era." He then open-sourced a chat protocol based on BLE Mesh called BitChats, aiming to enable people to connect freely and securely with each other when any network infrastructure collapses. The community responded quickly, and in recent months, field tests have been completed in multiple extreme scenarios.

Which are the primary technologies used for building your product?

Bit-Chat.xyz's answer:

Bluetooth Low Energy Mesh (Native BLE APIs on each platform)

X25519 Key Exchange + ChaCha20-Poly1305 Encryption

LZ4 Message Compression

Swift & SwiftUI (iOS/macOS Clients), Kotlin/Java (Android Clients)

Rust (cross-platform core library, responsible for protocol and encryption implementation)

Next.js + TailwindCSS (official website/documentation site, TestFlight, and other front-end displays)

Who are some of the biggest customers of your product?

Bit-Chat.xyz's answer:

(As BitChats is an open-source project, there are no traditional "paying customers," but it has been adopted in production environments by the following organizations/communities)

Red Cross: Communication at disaster relief sites

Doctors Without Borders: Contact at remote medical outposts

Burning Man Festival: Personnel coordination in high-density, high-traffic scenarios

TechCrunch Live Reporting Team: Blackout Demos and Stress Tests

Open Source Security Research Community: Protocol Audits and Secondary Development
