Certification Demonstration Overview

The scenario we choose is the certification process and the roles contain:

  • Student: As a holder, a student is able to arrange his or her personal data and claims with verified carriers.
  • College: As an issuer, a college can issue verifiable claims to the holders after verifying students’ identity.


Step1: Register the Decentralized Identifier

At first, students (holders) have to create new digital identities on Tangle and the registration includes 2 steps:

  1. Download the application (APP) on devices, such as mobile or tablets
  2. Create a new account and sign in

Step2: Sign in by Verifying the Digital Identity

Prove Own Control of Student Identity

After the accounts created, the next step is Sign in. Students (Holders) are required to scan the QR Codes provided by the website in order to decide what data will be revealed.

Step 3: Self-sovereign Identity Interaction

Issue College Degree Claim
