(a) — Item passport

One item, one identity, its whole history.

A report describes an item on a given date. The passport brings them together over time: every verified inspection of the same item, from one owner to the next.

(b) — How it builds up

  1. 01

    First report

    At sealing, the item receives a permanent Dorynn ID (DY-…). The report becomes the first entry in its passport.

  2. 02

    Later inspections

    Resale, servicing, a new buyer: each new report joins the same passport, only if the expert confirms that the serial number observed is the item’s own.

  3. 03

    A link to share

    You attach the passport link to your listing. The buyer sees the full history and verifies each report with its reference and fingerprint.

(c) — Example

What a passport looks like.

Fictitious example: the item, dates, references and experts are made up for illustration. A real passport opens from the link sent with your report.

(d) — Its limits

What the passport does not do.

Verify a report
  • It does not guarantee the item’s current condition: each report describes what was observed, on its date.
  • It does not estimate the item’s value.
  • It shows neither the serial number nor the identity of successive owners.
  • It is not public: only the people you send the link to can view it.
  • Without a serial number confirmed by the expert, a report stays alone in its passport: nobody can graft an inspection onto another item’s history.
