Educational Degree NFT DApp

Overview

This DApp enables educational institutions to issue and manage digital degrees securely on the Ethereum blockchain as non-fungible tokens (NFTs). The DApp consists of two smart contracts: Degree.sol and Token.sol.

Smart Contracts

Degree Contract

  • Token Minting: Admin users can mint unique tokens representing degrees and associate them with specific student addresses. Each token is minted with a unique ID derived from the student's address.
  • Admin Management: The contract allows the designation of administrators who have the authority to perform privileged actions such as setting other admins, adding students, marking students as graduated, and managing courses.
  • Student Management: Admins can add students to the system, associating them with their Ethereum addresses and names. The contract keeps track of each student's graduation status and courses.
  • Course Management: Admins can add courses for students, including the course name and associated GPA. Students can view their enrolled courses and hide or reveal specific courses as needed.

Token Contract

  • ERC-721 Compliance: Adheres to ERC-721 for creating and managing NFTs.
  • Metadata Support: Utilizing the NFTokenMetadata contract, degNFT supports associating metadata, such as a URI, with each NFT. This allows additional information about each degree, such as details regarding the degree holder and the associated educational institution, to be stored off-chain.
  • Ownership Management: Only an admin or the entity deploying the contract can mint NFTs.

How it Works

  1. Admins use Degree.sol to mint NFTs for students.
  2. Token.sol manages NFT metadata with details about the degree and holder.
  3. Students and admins interact with the DApp to manage courses and graduation status.
