Nearssage

Talk with nearby people 📍

An app I envisioned answering to a demanding necessity I've noticed in my environment, people (at least where I live) don't strive to socialize even when meeting, they rather spend their time on social media instead of talking in real life. Fun experience: people in a terrace chatting on Instagram with someone sat a few tables away.

What is this? 🧐

Well, an app to chat and meet people nearby you. But, why near you and not worldwide? Because this isn't a social messaging app made to hook you, is an app to meet people in the real world.

Design 😏

All messaging app should be transparent on how they work, here is a brief description:

Client

Chat (E2EE)
- X3DH + CSIDH - (Blake3) Exploring to remove CSIDH as it may have no cryptographic benefits
- Double Ratchet - Yet to do

Server

Binary protocol
- Key agreement - ECDH
- Encryption - ChaCha20
- Integrity - CRC32
- Replay attack mitigation
UDP Transport
Embedded key-value ~~distributed~~ database

You can check out this by yourself!
