Check the serial number or Golova ID before buying: whether the equipment is reported stolen, who issued it and whether it is anchored in the blockchain.
The passport registry is not connected to this wiki installation.
The owner issues a passport in the Golova CRM for a specific device: serial number, photos, parameters. The QR sticker leads to this check.

A marketplace sale is recorded in the passport; the ownership history continues with the buyer. The history root is anchored in the blockchain.
