 # Nim Chat POC
 
-This is a technical proof of consuming the [chat_proto](https://github.com/waku-org/chat_proto/tree/base_types?tab=readme-ov-file) in nim.
-
-
-This POC introduces the following Conversation Types:
-- Inbox : Asymmetric channel for receiving invites
-- PrivateV1: 1:1 private messaing with Forward Secrecy and Post compromise security
-
-Messages are delivered over Waku
+This is the technical proof of a modular e2ee chat protocol using Waku. You can find discussion and details [here](https://github.com/waku-org/specs/pull/73)
 
 See [EchoBot](./examples/bot_echo.nim) for a minimal client side usage example.

 ### Message Flow
 
 To establish a secure conversation, Saro and Raya need to:
-1. Exchange key material
+1. Find each others identityKeys
 2. Agree on a secret key, and location to communicate
 
-For this technical proof, recipient identity keys are exchanged out of bound via an invite link. More complex identity systems will be explored in the future.

-Key derivation and message framing is defined by Inbox spec

 ## Limitations
 
 1. `.proto` files are included in this repo due to complications in importing nested packages using `?subdir=`. Once resolved there will be a single definition of protocol types.
-1. Currently messages are not sent over the wire. They are simulated using a `TransportMessage`.
+1. Messages are sent using waku, however wakunode discovery has not been implemented. As a stopgap a manual discovery process based on staticpeers is used.
