XMPP vs Signal: A Cryptographer's Ranking and DEF CON Village Rant

Ah, the Codeberg Drama

I share my personal ranking of messaging protocols, placing XMPP above Signal and Matrix despite its fragmented user experience. I also announce my new role as a Senior Cryptography Researcher at Horizen Labs, focusing on zero-knowledge proofs. Finally, I offer a candid, humorous critique of my recent DEF CON experience, highlighting the disappointing atmosphere at specific villages and the absurdity of merchandise sales.
