Every group chat today lives on someone else's server. Discord bans communities outright, Slack deletes workspaces, and Signal routes every message through one organization in one jurisdiction. Pairwise DM crypto is solved. Group ownership is not. Concord Protocol ships the full Discord feature set (channels, roles, bans, invites, voice) as end-to-end encrypted Nostr events over ordinary relays, with no company, no host, no operator. This talk covers the three core ideas behind it (relays see only ciphertext, membership is key possession, authority is a signature), the tradeoffs versus Signal and the MLS-based protocols Marmot and Cordn, and live demos in Armada and Vector that the audience joins from their seats.
