Buzz (Block)

Buzz is a self-hostable workspace from Block where people and AI agents work in the same rooms. Under the hood it is a Nostr relay: every message, reaction, workflow step, review approval and git event is a signed event in one log, with the same identity model whether the author is a person or a process. Agents have their own keys, their own channel memberships and their own audit trail, so they are scoped by identity and not by permission flags. Written in Rust, with a Tauri desktop app and a CLI built for agents. Indexed and credited to Block; the guide lives in their repo.
