In Nymbrink the record is signed and verifies with the open Provenance tools. This sample is not signed, and says so inside the file. Check a real signature yourself.
Do this with your own suppliers
Sign in with your email and enter a supplier’s web address or the address of its policy page. No passport is needed: where a supplier publishes none, Nymbrink watches its public wording instead. Your list starts empty — none of these examples are copied into it.
