The outside anchor (check 11)

Everything in checks 1 to 10 is served by our own servers. A server that lies could lie consistently. Check 11 adds one witness we do not run.

1. Every hour the 4-region cluster signs a proof that links to the one before it by hash.
2. Once a day the head of that chain is logged in Sigstore Rekor, a public, append-only log run by the Sigstore project, not by FIRME AI CORPORATION. After that nobody, including us, can rewrite or backdate an earlier proof without it showing.
3. Your browser downloads the head proof, re-hashes it, and checks the hash equals the logged head and that the anchor is under 48 hours old.
4. The last step is one click: open the Rekor entry and compare. This site's security policy does not let a page call other domains, so the page cannot read Rekor for you.

Today we read the entry directly: log index 3637735391, logged data SHA-256 2d28d95a547e7e8127a70fbc…, matching the published anchor.

What it does not prove: that the proofs' contents are true, or who holds the signing key. The quorum receipt used in checks 2 to 4 is not itself logged in Rekor yet.

FIRME AI CORPORATION · CAIN-42 is a Byzantine trust fabric. Numbers marked "our own check" were run by us, not by an independent party. Nothing on these pages is a certification.
