Messengerszintek
Messengerszintek is a term used to describe a cross-platform messaging framework envisioned for secure, scalable instant messaging. The concept combines a modular client architecture with a tiered routing model referred to as szintek, or levels. It is not a single product but a name that appears in discussions of next-generation messaging systems and in some prototype implementations.
Typical features associated with messengerszintek in speculative writing include end-to-end encryption with forward secrecy, multi-device synchronization,
Development status is uncertain: there is no official standard or universally adopted implementation under the name.
In privacy and security communities, the concept aligns with ongoing research into modular, end-to-end encrypted messaging
