Hasan Toor: Block launches Buzz on Nostr with AI and human agents — Block unveils Buzz on Nostr protocol

Hasan Toor, co-founder at Toor, reports that Jack Dorsey has just spent a product launch demonstrating technology that Kylon has been offering for several months.

According to Toor, Block introduced Buzz on July 21, a free and open-source platform built on the Nostr protocol. The product enables both humans and AI agents to participate together in channels, with each agent carrying its own cryptographic identity, rather than relying on a human's credentials.

But we saved everything 🙂.

Toor has previously highlighted developments in AI agent integration with blockchain tools. He reported that AI agents can access over 20,000 tools via Apify using USDC on Base without requiring an account or API key. That solution also enabled per-run payments through Coinbase.
