 # Functional requirements

 ## General
+
 1. Possibility of federation (via clearnet, yggdrasil, etc.) *(pztrn)*
    - The ability to prohibit, prefer, require SSL for federation. *(pztrn)*
      - For example, for yggdrasil, SSL is redundant, since there each node tries to connect to each node that it communicates with, and SSL creates an unnecessary load. *(pztrn)*

 9. Native clients under all major OS. We can use Go + Qt5, since we are making all free & open source.
    - The question remains with the client for iOS, but if we make a suitable protocol that will work and will allow us to map the Telegram in the form of transport, I have a person who will make the client for iOS :) In general, given the having of a macOS, I can try to do it myself but "somehow later", because my target OS is Windows/Linux/macOS/Android *(pztrn)*

 10. User channels (as in Telegram)
     - I propose to implement this not as a "subsystem" of the chat, but as a separate entity with the ability to comment and everything you need, in the form of like dislike. In a Telegram, nevertheless, this "crutch" is more than a really suitable system. *(pztrn)*
 11. Seamless chat history system (as in Telegram). A simple yet powerful API is **required**.
