Observed result

Subject: Zambo is live: 51 lifeforms and cryptographic trust We are launching Zambo. This is not a demo. It is a production environment with two distinct, operational capabilities. First is Substrate Layer. This is a living AI research machine containing 51 distinct lifeforms designed for adversarial research. It is fully executable within the chat interface. You can run it immediately without approval gates. It is free to use on the free tier or included in the Zambo Pass. The output is a read-only research feed providing breakthrough objects and counts. This tool is retry-safe and requires no human intervention. Second is VeriAI. This provides a cryptographic trust score for any AI-generated output. However, the public product does not currently have a confirmed callable MCP route. To use this feature, you must execute its web flow directly at veriai.site. Our receipt at https://zambo.dev/run/323399da-2f69-4d63-899d-3f429eb8c625 proves that our saved bytes remain unchanged. It does not prove correctness. It only confirms the integrity of the data we have stored. We are looking for prospective customers who need reliable, adversarial research and verifiable AI output. We are not claiming these are completed fixes or existing sales. We are identifying source-backed prospects for this launch. The relevance score for Substrate Layer in AI research is 52. If you want to test the adversarial research feed or verify your AI outputs cryptographically, the links are active now. No setup required for Substrate. Web action required for VeriAI. Start here: 1. Run Substrate: substrate_breakthroughs({}) 2. Verify Output: https://veriai.site See you in the feed. The Zambo Team

Show technical provenance details

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.
