This project develops a blockchain-based system to prevent cheating in in-class polls
by ensuring secure and private user verification. By incorporating Zero-Knowledge Proofs
and blockchain technology, the system provides a tamper-proof and decentralized method
for validating user identities, thus preserving the integrity of the educational assessment
process and ensuring fair evaluations of student performance.

Create A Class

The "Add New Class" feature is a crucial part of the system, enabling teachers to dynamically create new classes. This feature streamlines the process by providing a user-friendly interface where teachers can input the name of the class they wish to add.

Delete A Class

The "Delete Class" functionality allows teachers to remove classes from their list. Once a class is deleted, it cannot be recovered, so caution is advised.

Create A Quiz

Teachers can create quizzes for any of their classes. Once a quiz is created, it receives a unique access code that students need to use to access blockchain verification. This allows for seamless two-step verification for students' projects.

Join a Quiz

Students must enter a unique 5-digit code to join a quiz. After entering the code, a QR code is displayed. Students need to scan this QR code from a unique address on the blockchain to fully verify their identity.

Teacher and Student Login

Both teachers and students have unique login pages.

Verifying Student Identity

Let's delve into the process of adding and authenticating students. To illustrate this, follow these steps:
Sign in with your teacher account.
Add a class and press enter.
Navigate to the "Manage Class" section and select "Add Student."
Enter the previously provided GNumber and press enter.
Within a few seconds, the associated ProtonMail account will receive an email containing a JSON file.
Download the JSON file to a mobile device with the Dock Cert app installed.
Open the Dock Cert app and navigate to the credential section to import the JSON file. This links the ID to the class.
When a student attempts to take a quiz, a QR code requesting an ID will appear. To complete the verification process, present the ID along with the class name.
