Proof, not promises

Verify us. Don’t trust us.

Every operating system we certify is sealed into a live, tamper-evident hash chain. Here is the current chain head — anyone can re-link it and check.

Verifierverify_record.mjs — re-links the chain and re-probes each product live

How to verify

  1. Take the chain head above.
  2. Run the open verifier (verify_record.mjs), which walks every sealed record, recomputes each link, and re-probes the live product behind it.
  3. If a single record was altered after sealing, the recomputed chain head will not match the one published here. That is the whole point.
Honest scope. A seal proves provenance and integrity — that a system was certified, on specific data, and has not been altered since — not that every decision it makes is correct (that is a separate, harder problem of tests and formal proof). All figures are self-measured and not yet third-party audited, and the count moves as we re-verify: a product that fails a re-check is demoted, so this number can go down as well as up. We would rather show you that than hide it.
