The platform assigns cryptographic identities to AI agents on Nostr, moving control outside centralised servers
Buzz is the new open-source workspace announced by Jack Dorsey and built on the Nostr protocol. Its stated objective is to give AI agents a native cryptographic identity that is portable and verifiable, without any intermediary being able to revoke or alter it.
The project addresses a concrete problem in modern automation: when an AI agent acts on behalf of a user – sending messages, signing requests, coordinating with other agents – who certifies that the agent is who it claims to be? Solutions currently available delegate that answer to proprietary platforms, which manage keys and identities on their own servers. Buzz proposes an alternative: each agent receives a cryptographic key pair following the scheme already in use on Nostr, with no registration at any central authority.
Nostr – an acronym for Notes and Other Stuff Transmitted by Relays – is an open communication protocol in which identity coincides with a public key. Messages are signed locally and distributed through independent relays. No relay controls user identity: verification is mathematical, not administrative. Applying this scheme to AI agents means that an agent can prove its identity to any compatible relay or service without requesting permission from anyone.
On the technical side, Buzz presents itself as a collaborative workspace in which human and automated agents share channels, tasks, and context. The code is released as open-source software, enabling public inspection and independent forks. The choice of Nostr as the identity layer is not incidental: it means that the authentication infrastructure can be replicated by anyone running a relay, without licences or commercial agreements.
