Block launches Buzz, an open-source workspace where AI agents hold cryptographic identities and sign their own work with traceable authorisation chains, built on the Nostr protocol. The tool replaces Slack and GitHub-style agent integration with keypair-based accountability, addressing a governance gap where 68% of organisations cannot distinguish AI from human actions.
This Wire brief sits within Fusion42's coverage of AI Agents, Enterprise Software and Developer Tools, and 2 sources have reported it between 21 Jul 2026 and 23 Jul 2026.
◆ ◆ The Wire takeaway
If you're selling agent governance, audit, or containment tools to enterprises, Buzz just made your pitch harder: Block has open-sourced the technical standard that solves the problem you charge for. You now need to compete on deployment and integration, not the core capability.
