Batch attestations
Every production batch this factory has attested on a public chain. Each attestation records the SHA-256 of that batch's laboratory report, so the report in a buyer's hands can be compared with the one that was filed.

What an attestation proves. That the laboratory report file for that batch existed at the recorded time and has not been changed since — the SHA-256 in the transaction is the fingerprint, and you can compare it against the PDF in your hands.
What it does not prove. It does not prove that the product is approved for any market, and it does not prove that the product is good. Approval is the market authority's decision; quality is the laboratory's. An attestation proves one thing only: that a file has not been swapped.

Read this before you rely on the table above. No batch has been written to the chain yet. When one is, this page will list it here with its transaction, and anyone will be able to read that transaction on the block explorer — the same way they can read anyone else's.
Where to go from here
No batch has been written to the chain yet, so the table above is empty. The evidence this factory holds today is the set of third-party laboratory reports — each with its number, the laboratory that issued it, the file itself, and the products it covers.
