Instantly verify a Codex proof

Verify that a document, photo or agreement was recorded at a specific moment, using an independent and public proof.

✔ No access to the document
✔ No storage
✔ Instant verification

Verify with a Codex ID

Enter a Codex ID to confirm the existence of a proof in the public registry.

Direct access to the public registry

From photo to proof

Take a photo, generate a timestamped proof, and verify it instantly.

How verification works

Each proof receives a unique Codex ID
The ID is recorded in a public append-only registry
No document is stored — only its cryptographic fingerprint

Codex-Log acts as an independent trusted third party.

Codex proof verification

Codex-Log allows you to verify the existence and timestamp of a recorded act in an independent registry, without ever accessing the document itself.

Verification is performed exclusively using the Codex ID.

Using a CODEX ID:
If you have a Codex ID (e.g. CDX-XXXX-XXXX), you can instantly verify that it corresponds to a valid record in the public Codex-Log registry.

This ID is the unique reference of the proof. It confirms the existence of the act, its timestamp, and its integrity.

No document is stored and no personal data is retained.
Only the cryptographic fingerprint associated with this ID is recorded.

Codex-Log acts as an independent trusted third party, ensuring public, neutral and verifiable proof.
