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:

• Decentralized
  Colla Network is an unstoppable Web3 decentralized peer-to-peer communication and storage network, Colla DApp (e.g. CollaChat) connects to it via Colla Node. There is no centralized storage and control of user data, users can specify which Node(s) or even easily setup own Node(s) to connect to.
• 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 (i.e. Colla DApp, e.g. CollaChat) and server (i.e. Colla Node) are free and open source for anyone to download, install, run and build own deployment.
