FAQPage Schema
How do I format the issuer property in a W3C Verifiable Credential?▼

The issuer property in a W3C Verifiable Credential must be formatted as either a resolvable URL string or an object containing an `id` field with a resolvable URL, adhering to VCDM 2.0 standards for proper identification and discoverability.

What are the syntax options for defining a W3C VCDM issuer?▼

W3C VCDM issuer syntax options include providing a direct resolvable URL string or an object containing an `id` property with a resolvable URL, ensuring verifiable credentials meet VCDM 2.0 specification requirements for issuer identification.

Does the W3C VCDM issuer property require a resolvable identifier?▼

Yes, the W3C VCDM specification recommends using a resolvable identifier for the issuer property to enable proper identification and verification of the verifiable credential's source.

Why should I use a URL for the issuer field in verifiable credentials?▼

Using a URL for the issuer field in verifiable credentials ensures the identifier is resolvable, which guarantees discoverability and allows verifiers to validate the credential's source according to VCDM 2.0 specifications.

When do I need to define an object with an id for the VCDM issuer property?▼

You define an object with an `id` for the VCDM issuer property when you need to specify the issuer's resolvable URL identifier while leaving room to potentially include additional metadata about the issuer within the verifiable credential.

What is the W3C VCDM issuer recommendation for verifiable credentials?▼

The W3C VCDM recommendation for verifiable credentials advises formatting the issuer property as a resolvable URL or an object with a resolvable URL `id` to ensure correct issuer identification and verification.
