This demonstration will show you the state-of-the-art certification issuing process. In this scenario, the student will be asked to scan a QR code via our APP to get a certification from this course website. The website will present the QR code to obtain the necessary credentials with user permission. Once the website receives the credentials, the website manager can then issue the certification to the user via a notification, and the certification will be permanently recorded on the Tangle. Press the "Start" button to continue."
