Verifiable Credentials

What is a verifiable credential (VC)?

VCs are a W3C standard for digital, cryptographically verifiable
credentials. This means they can be stored on digital devices, and
you can use cryptography to verify their data and authorship.

Explore use cases for VCs

The following code snippets and UI examples show the main components
of a VC and how you can encode them and visualize them. Pick
different samples using the tabs to go over various use cases. Learn

Type  
A credential can have one or more types. It is specified in an array
of strings/URIs. The "VerifiableCredential" is mandatory.

The credential type can be used to determine if a specific credential
is appropriate for a particular use case. For example, a credential
of type "UniversityStudent" might be useful to enter a college
campus, but not a company campus.

How VCs work
Understanding the use cases

Stages

1. Credential issuance & storage

A user (Subject) requests a credential from an Issuer. The Issuer
includes data about the Subject in a digital credential, including
the Subject's identifier--the issuer signs the VC with its private
key.

The user receives the VC and stores it in a digital wallet. The
digital wallet allows users to store and present VCs of any type.

2. Credential presentation

Later, the Subject is using an application that wants to verify the
Subject has a particular VC. The Subject uses the digital wallet to
present the credential to the Verifier, signing a Verifiable
Presentation (VP) with the Subject's private key.

3. Credential verification

The Verifier cryptographically verifies the VP (it was signed by
Subject and original VC signed by Issuer) and checks its validity
(for example, it hasn't expired). It obtains the Subject and Issuer
public keys from a Verifiable Data Registry.

Use Cases

ID card

Represents an ID card that can be issued by a country or a province/
state within a country. Could be used to prove residence, age,
nationality and other aspects.

University degree

Represents an degree issued by a University to indicate a person has
a graduated with a specific degree. Could be used to apply for jobs
for example.

Vaccine proof

Represents proof that a person was vaccinated with a specific vaccine
by a health institution. Can be used for validation before traveling.

Employment credential

Represents the fact that a person is an employee at a company. Can be

site like Linkedin.

Learn about Verifiable Credentials by using them
Obtain your first credential using ID Wallet, a sample Web Wallet
app. Learn how credentials are verified using the Presentation
Debugger tool.
 

Obtain a Verifiable Credential

Use ID Wallet (a sample Web Wallet app) to obtain Verifiable
Credentials. By default you can obtain employee cards, vaccination
cards, university degrees and ID cards. You can also use Auth0 to
define your own credentials and use ID Wallet to try them out.

Present a Verifiable Credential

Use ID Wallets to present Verifiable Credentials to a verifier.
Explore the content of these presentations using the
verifiablecredentials.dev Presentation Tool. You can also create a
custom credential verifier using Auth0 and use ID Wallet to present
credentials to it for validation.
