 ## What is the Entra Verified ID Network?
 
-In our scenario, Proseware is a verifier. Woodgrove is the issuer. The verifier needs to know Woodgrove's issuer DID and the verifiable credential (VC) type that represents Woodgrove employees before it can create a presentation request for a verified credential for Woodgrove employees. The necessary information may come from some kind of manual exchange between the companies, but this approach would be both a manual and a complex. The Entra Verified ID Network makes this process much easier. Woodgrove, as an issuer, can publish credential types to the Entra Verified ID Network and Proseware, as the verifier, can search for published credential types and schemas in the Entra Verified ID Network. Using this information, Woodgrove can create a [presentation request](presentation-request-api.md#presentation-request-payload) and easily invoke the Request Service API.
