Question 1

What exactly is PeerChat?

Accepted Answer

PeerChat is a decentralized, serverless communication platform. It allows users to send encrypted messages and files directly between devices by forming a temporary or stable mesh network using Bluetooth and WiFi.

Question 2

How does it work without internet?

Accepted Answer

PeerChat turns your device into a node in a mesh network. It uses BLE (Bluetooth Low Energy) for discovery and small data packets, and WiFi Direct or WiFi Hotspot for high-speed file transfers.

Question 3

Is my data secure?

Accepted Answer

Yes. Every message is end-to-end encrypted (E2EE) and digitally signed using Sodium (libsodium). Only the intended recipient can read your messages.

Question 4

How does multi-hop mesh routing work?

Accepted Answer

If a destination is out of range, PeerChat can automatically 'hop' the message through intermediate nodes. Each hop is encrypted, so intermediate peers cannot read the content.

Question 5

Is PeerChat open source?

Accepted Answer

Yes, PeerChat is fully open source. You can audit the protocol and the code to verify its security claims on GitHub.

Question 6

What are the hardware requirements?

Accepted Answer

PeerChat is optimized for Android devices with Bluetooth 4.2+ and WiFi capabilities, supporting everything from legacy phones to modern flagships.
