Verification Trust Levels

Gold Verification

Signature is cryptographically valid and the issuer's DNS records confirm the public key. This is the highest level of trust.

Silver Verification

Signature is valid but DNS verification is not yet configured. The reference is authentic but cannot be tied to the domain.

Invalid

The signature check failed, the reference was not found, or it has been revoked by the issuer. Do not trust this reference.

How does verification work?

RefPassport uses Ed25519 digital signatures and DNS TXT records to prove that a reference was issued by the claimed domain. The signature is checked against the public key published in DNS. No middleman, no trust assumptions.
