Essential Credential Schemas

Essential Credential Schemas (ECSs) are the Verifiable Trust basic needed schemas for enabling a minimum trust resolution in Services and User Agents by answering these questions:

  • who is the provider of this Verifiable Service?
  • what is the minimum age required to access this Verifiable Service?
  • is the User Agent trying to connect to a Verifiable Service a Verifiable User Agent?
  • ...

The Verana Foundation defined an Ecosystem Governance Framework and created a Trust Registry in the Verana Verifiable Trust Network (VVTN) for providing Essential Credential Schemas (ECS) to the community. Governance framework will be published in the foundation website.

There are 4 kinds of ECS:

  • Service;
  • Organization;
  • Person;
  • UserAgent.

Service schema is OPEN to anyone. Participants that want to obtain an Organization, Person, or UserAgent Verifiable Trust Credential (VTC) must contact an authorized issuer and perform a validation process in order to obtain their credential.

Remember the popup presented by a Verifiable Service: in this example you can see that information comes from Organization and Service Verifiable Trust Credentials (VTCs).
