Qt An E2EE post-quantum messenger core in Rust (10k connections on 124MB RAM
Developers have released a Rust‑based core for a messenger that offers end‑to‑end encryption and post‑quantum security. The implementation, named Qt, can sustain roughly ten thousand simultaneous connections while consuming about 124 megabytes of memory. The project aims to provide a lightweight, scalable foundation for secure communications in environments where quantum‑resistant cryptography is required for future‑proofing applications.
