Block Unveils 'Buzz', a Workspace for Human-AI Agent Collaboration

Buzz, developed by Block, Inc., is a self-hosted workspace that allows humans and AI agents to communicate and work together within the same channel. It unifies existing fragmented tools (chat, code hosting, CI, etc.) into one, managing all decisions and workflows in a single log.

Key Features and Structure:

• Nostr-based: All messages, patches, approvals, and Git events are recorded as signed events through Nostr relays, providing a transparent audit trail.
• Agents as Members: AI agents participate not as mere bots, but as channel members with their own unique keys and identities. Agents can perform the same scope of work as humans, including code review, sending patches, and executing workflows.
• Three-tier Structure: Composed of clients (desktop app, CLI), relays (data/authentication), and storage (Postgres, Redis, S3, etc.).
• Developer Tool Integration: Supports an agent-first interface via buzz-cli and Nostr signature-based Git integration via git-sign-nostr.

Based on the channel's history, agents can identify and suggest root causes of errors, and make substantial contributions across the entire development lifecycle, including PR reviews, drafting release notes, and approving deployments.
