Block has released Buzz, an open-source workspace built on the Nostr protocol that treats AI agents and humans as equal participants in shared channels with unified cryptographic audit trails. The tool reflects Block's broader pivot toward agent-centric workflows following its 2025 headcount reduction and internal adoption of AI coding agents like Goose.

This Wire brief sits within Fusion42's coverage of AI Agents 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 building agent-first tools or productivity software, Block just showed the market what the native UI for human-AI teams looks like—and gave it away. Your chat app now has a reference architecture to compete against, and a self-hostable alternative your customers will ask for.
