Announcement post from Block Engineering signed by Thomas Petersen (Principal Designer & Builder), published on August 18, 2026, introducing Buzz Projects — the forge building block of Buzz, Block's humans+agents workspace built on Nostr.

The problem stated. « Software development tools are fragmented in ways the work itself is not. » The bug report sits in one tool, the discussion in another, the fix on a branch, CI elsewhere, the review in a comment thread, release notes reconstructed after the fact. The thesis: all of this is one conversation, and the history must be part of the project.

Every push, review, approval, and merge is a signed Nostr event. If an agent authors a patch, you can see which agent produced it and which human authorized that agent to act

What Projects delivers. A forge hosted on your own relay: standard Git repositories accessible via fetch/clone/pull/push over Smart HTTP, « with no custom tooling or wrapper CLI required »; the clé Nostr as a single identity« the same npub that signs your messages signs your pushes », with no separate token or GitHub account; multi-repo projects that can include repositories one doesn't own (« you just won't have authority over it »); issues, pull requests, diffs, inline comments, review and merge; a server-wide activity feed; and the linking of any project to any number of channels, so that « the context around a change doesn't disappear the moment agents start writing code ». From a channel, an issue can be handed to an agent or the agent can be asked to open a PR, which links back to the conversation that produced it; the agent reaches out to the human via the Inbox.

The doctrine, in two parts the post never assembles. On one side, no prior constraint: « No forced guardrails, no limitations on what your agents are allowed to help you with. » On the other, a signed record of every act: « Every push, review, approval, and merge is a signed Nostr event », with a trace of which agent produced a patch and which human had authorized it. Hence the closing projection: contribution history becomes « more than a set of colored squares on a profile », a verifiable history attached to a key, and Block states it is exploring « agent trust protocols informed by past behavior ». Trust shifts from ex ante authorization to ex post proof. The associated framing is explicit: « A terminal gives an agent somewhere to execute commands and change files, but it does not give it a persistent place in the network. Buzz does. »

Caveats. No figures, no outbound links, no specification anywhere in the text; CI and release notes are promised but absent from the inventory; Projects lives under the Experiments tab, and the post disqualifies itself six times — « Buzz is still in beta and Buzz Projects is still under experiments, so treat it accordingly. »
