You host your own service, which can also federate with other Databag nodes. It is Public-Private key based identity (not bound to any blockchain or hosting domain) and End-to-End encrypted (the hosting admin cannot view sealed topics, default unsealed).

This is not a service for finding friends in your contact list. You, or your organisation, hosts the service, and has completely private and secure chatting amongst yourselves.

Another use-case may be if you are visiting a foreign country which blocks many public messenger services. This app would connect back to your private server, which is very unlikely to have been blocked.
