Observed result

**Subject:** Zambo is live: AI research with cryptographic trust You’ve likely exhausted the current noise in AI tools. Zambo changes the dynamic by combining live research engines with verifiable integrity. We are launching two core capabilities today. First, **Substrate Layer** acts as a living research machine. It processes adversarial data streams to surface breakthroughs without hallucinated fluff. Second, **VeriAI** attaches a cryptographic trust score to any AI-generated output. This solves the critical gap in enterprise adoption: you can now prove source-backed accuracy, not just claim it. These features are currently in execution mode. While our internal LeadSignal scan for Austin web design prospects returned zero qualified leads (a strict result, not an error), the underlying infrastructure is fully operational. We do not invent customers. We provide the receipts. Every run generates a unique, immutable receipt URL. This proves the specific bytes saved and the logic executed. It is a transparent audit trail for your team. **Next Step:** Test the workflow. Run a simple query through the Substrate Layer. Then, verify the output’s trust score via VeriAI. Upon completion, copy the generated receipt URL. [Link to Zambo Dashboard] If the output meets your integrity standards, share the receipt with your stakeholders as proof of process. This is not a promise of sales; it is a demonstration of capability. Best, [Your Name] [Your Title] Zambo

Provenance for every timeline entry

  • EXECUTED BY ZAMBOZambo ran the tool call itself.
  • OBSERVED VIA GATEWAYA Zambo gateway observed request and response bytes from the named external executor. Zambo did not run that external action.
  • LOGGED BY AGENTAn agent or local hook reported the action. Zambo attests that the record is unchanged since logging, not that the action happened as described.

Private agent reasoning, built-in client actions, and direct calls to unrelated MCP servers are not included unless an agent or gateway reports them.

What is an execution receipt?

An execution receipt is a public record of a reported AI agent tool call. Its byte commitment and provenance claim can be checked independently; neither alone authenticates the issuer. Read the canonical definition of an AI agent execution receipt.

What the receipt can and cannot prove

What is this?

Zambo's receipt store reports a tool call and records its result. The SHA-256 commitment covers the exact canonical bytes. The provenance label is bound to v0.4 receipt bytes when that check passes, but no pinned signature or trusted issuer key is checked. An anchor can timestamp a fingerprint; it does not authenticate the issuer.

Receipt commitment: commitment matched; issuer, signature and chain not checked. This checks the saved bytes, not whether the answer was correct. Recompute the SHA-256 commitment in your browser. Open the API v2 JSON response to inspect the machine-readable checks. See the Nostr anchor event on a public viewer. The fingerprint is timestamped outside Zambo too.
