I apologize for that. There was an assumption that most people were aware of the Handshake Naming system [1]. Handshake is a naming blockchain that's recently been gaining adoption quickly (Namecheap [2]) (Opera Browser [3]). Using this, you can control your name, which is your identity, on the internet. There's a lot of other cool benefits, but as it pertains to this project, it's the names, cryptographic proof of ownership of said names, and the cryptographic provability that the messages were written by the owners of said name.
There are many ways to get Handshake names, but the easiest ways are to use Bob (non custodial) [4] or Namebase (custodial) [5].
