## What is CollaChat?

CollaChat is an open source private and decentralized messaging app owned by no one and everyone. It is aimed to leverage blockchain technology to put users back in control of their digital communication, while preserve user experiences that they know and love.

Distinguished from the traditional messaging apps, CollaChat has three most important features which revolutionize the communication infrastructure:

- End-to-End Encrypted
All messages are end-to-end encrypted, only author and intended recipients can see the content.
- Open Source
Both Colla Network client side (i.e. Colla DApp, e.g. CollaChat) and server side (i.e. Colla Node) are free and open source for anyone to download, install, run and build own deployment.

CollaChat supports Web/Mobile/Desktop and Multi-device. It has most popular messaging and social functions:
