The Scealia certificate,
explained line by line.

This is what the document you produce before an opposing party, a judge or an insurer looks like. Each area is explained, including what the certificate does not attest.

Example shown for illustration purposes: all data (names, dates, fingerprints, numbers) are fictitious.

1

The level of certification

There are two versions: the timestamp certificate, shown here (recording on the blockchain only, free of charge), and Constat Scealia, which adds the qualified eIDAS electronic seal. The badge states the status of the proof, here “Sealed proof”.

2

The attestation

Two sentences that anyone can understand: what the document establishes, the date, and the guarantee of integrity. No jargon on the first page; the detailed technical and legal grounds are set out in the following pages of the certificate.

3

Identification and fingerprints

The SHA-256 fingerprint is the file's unique signature: the file cannot be modified without its fingerprint changing. The certificate also gives the proof fingerprint, which links the file to its capture details, and the transaction that records it on the blockchain: it is fingerprints, not your content, that are recorded there. The colored dots help you compare two fingerprints at a glance.

Steps and place

Each step shows its time: the capture, as reported by the phone, then the public timestamp, the block time on the Polygon blockchain, which any third party can verify. Below, the place of capture on the IGN map, as recorded by the phone. Constat Scealia adds the qualified seal within the meaning of the eIDAS Regulation, which carries a presumption of integrity and of the accuracy of the date (Articles 35 and 41).

5

What it attests, what it does not

Transparency is what makes a proof credible. The certificate states its own limits: it says nothing about the truthfulness of the scene or the outcome of proceedings, and it does not replace a report drawn up by a commissaire de justice (French judicial officer).

6

Verification, with or without Scealia

The certificate can be verified online in a few seconds, with its QR code or at scealia.com/verify, but also without us: directly on the Polygon blockchain through a public explorer, and with any signature validator for the qualified seal. Your proofs do not depend on Scealia's survival.
