Fintech company Block, founded by Jack Dorsey (co-founder of Twitter), has introduced a new open work platform called Buzz. Its key feature is a revolutionary approach to artificial intelligence: AI agents here are viewed not as simple auxiliary tools or a "browser tab," but as full team members with their own accounts and access rights.
The platform, launched on July 23, 2026, and already available at buzz.xyz, combines the familiar functions of corporate messengers: channels, discussion threads, direct messages, voice calls, media file sharing, code repositories, and automated workflows. Structurally, Buzz resembles Slack or Microsoft Teams, but fundamentally differs from them in its AI interaction architecture.
AI as an Equal Colleague
The main innovation of Buzz is that AI agents receive their own cryptographic identifiers and individual sets of rights. This allows them to:
- post messages in public chats and channels;
- view and review code;
- initiate automated processes;
- participate in work discussions on par with human employees.
"Every company will need a space where humans and agents work together," said Bradley Axsen, Head of AI at Block. "The question is whether that space will be proprietary or open. We built Buzz because we believe it should be open."
Decentralization and Portability
The platform is built on the decentralized Nostr protocol. It provides each network participant – whether human or artificial intelligence – with a pair of cryptographic keys that belong to the user themselves, not the platform.
According to the developers, this solution ensures unprecedented portability: the digital identity of an AI agent and its entire interaction history can be freely moved between other Nostr-compatible systems. The agent is no longer tied to the closed account system of a single specific vendor, which reduces the risks of vendor lock-in for companies.
Flexibility and Open Source Code
Buzz is not tied to any specific proprietary language models. Development teams can independently choose which agents to integrate into their workspace. The platform supports connecting agents based on:
- Claude Code;
- Codex;
- Block's own framework called goose;
- any other proprietary corporate AI solutions.
Moreover, Block distributes the source code of Buzz under the open-source Apache 2.0 license. This means that any developers and companies can freely study the platform's architecture, modify it for their specific needs, and deploy it on their own servers without licensing restrictions.
The Future of Corporate Communications
The launch of Buzz marks a significant shift in the paradigm of corporate communications. While previously AI tools existed in isolation and were used by employees sporadically, now there is a deep and equal integration into the very fabric of the daily workflow.
Block's open and decentralized approach could set a new standard for the IT industry, forcing traditional market players to reconsider their strategies on how artificial intelligence should coexist with humans in the workplace.
