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. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.

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.
