24 alternatives to Decentralised Digital Identity and Messaging

I've been working on something for a while now. It's a combination of a decentralised identity system and a decentralised messaging system that makes use of the aforementioned new identity system. It's based on cryptographic keys with one major property: keys are paired with arbitrary mnemonic strings, e.g. your favourite username, so apps can send messages in a P2P fashion addressed to the strings directly without having to worry about IP addresses.

Hi, everyone. Been playing around with this recently as a sort of PGP successor.
