Jack Dorsey's Block Launches Buzz, a Nostr-Based Workspace for Humans and AI Agents
Jack Dorsey's Block has introduced Buzz, an open-source platform that facilitates collaboration between employees and AI agents. Built on the Nostr protocol, Buzz features team chat, code repositories, and automated workflows, aiming to reduce dependency on Slack and GitHub, according to Decrypt.
On July 21, 2026, Jack Dorsey's Block announced the launch of Buzz, a new free and open-source platform designed for collaborative work between humans and AI agents. Hosted on the Nostr protocol, Buzz integrates features commonly found in team communication tools, such as channels, threads, direct messaging, voice communication, media sharing, and code repositories.
Buzz is particularly notable for giving AI agents their own cryptographic identities, allowing them to contribute to discussions, review code, and execute automated tasks alongside human users. Jack Dorsey described Buzz on Twitter as "a new groupchat platform for teams of people and agents of all sizes", emphasizing its model-agnostic nature, meaning it can support a variety of AI models, including those from Anthropic and OpenAI.
According to Bradley Axen, Block's head of AI capabilities, "Every company is going to need a place where humans and agents work together. The question is whether that place is proprietary or open." This reflects Block's vision for Buzz as a self-sovereign and decentralized solution to the challenges of modern team collaboration.
The decision to utilize the Nostr protocol stems from Block's aim to address fundamental issues in collaborative work environments, including the need for privacy and security. A significant aspect of Buzz is its support for various AI systems, including Block's own open-source agent framework called "goose", enhancing its capabilities for automation and interactivity.
As organizations increasingly integrate AI into their workflows, platforms like Buzz that promote collaboration between human teams and AI agents may reshape work processes. It remains to be seen how Buzz will perform in the competitive landscape against established platforms like Slack and GitHub, particularly regarding user adoption and engagement. Blocks' choice of an open-source platform may also attract privacy-conscious users who are wary of proprietary solutions.
