Block's Buzz makes agents first-class teammates

Buzz's strongest idea is collapsing chat, code review, CI, and agent execution into one signed event log—but that ambition also makes adoption and operational simplicity its biggest challenges.

• –Agents get their own cryptographic identities, memberships, permissions, and audit trails instead of impersonating human users.
• –Git events, workflow runs, approvals, and conversations become searchable project history in the same workspace.
• –Self-hosting and Nostr-based relays offer control and portability, but require teams to operate more infrastructure than Slack-style tools.
• –The project is unusually relevant for developers building multi-agent workflows, especially through its CLI, ACP harness, and MCP tooling.
• –Replacing chat, forge, CI, and project memory at once is a bold bet that will need strong interoperability and reliability to stick.
