# Block Buzz: Shared Human-Agent Workspace

**Repository:** https://github.com/block/buzz  
**Stars:** 29.6k | **License:** Apache 2.0

## Workspace Architecture
- **Nostr Relay Backbone:** Operates as a self-hostable Nostr relay where all messages, code reviews, workflow steps, approvals, and git events are cryptographically signed events in an immutable append-only log.
- **Identity-Scoped Agents:** Agents are first-class team members with dedicated cryptographic keypairs and channel memberships ("scoped by identity, not permission flags").
- **Branch-as-Room:** Feature branches instantiate dedicated collaboration rooms combining git patches (NIP-34), CI status runs, agent reviews, and human merge decisions.
- **Agent Tooling:** Includes `buzz-cli` for machine-friendly JSON-in/JSON-out interactions and supports Agent Client Protocol (ACP) harnesses (Goose, Codex, Claude Code).
