Decentralized Instant Messaging Protocol (DIMP)

0. Abstract

This document introduces a new protocol designed for instant messaging (IM) and an architecture for developing decentralized IM applications. The software provides accounts(user identity recognition) and communications between accounts safely by end-to-end encryption.

It includes just TWO extremely simple parts:

1. User Identify
2. Messaging
