This repository contains the source code for a Blockchain-based Micro-Credentialing System aimed at securely issuing, verifying, and managing micro-credentials (digital certifications). The system leverages blockchain technology to ensure the authenticity and immutability of credentials, addressing issues like fraud and verification inefficiencies.
-
Decentralized Credential Storage: Credentials are stored on a blockchain network, ensuring tamper-proof records.
-
User-Friendly Interface: A clean and intuitive frontend for credential issuance and verification.
-
Secure and Transparent: Employs cryptographic hashing and blockchain features to ensure data integrity.
-
Scalable Architecture: Supports adding new users, issuing multiple credentials, and integrating with third-party systems.
-
Verification Mechanism: Provides a quick and reliable way to verify the authenticity of issued credentials.
-
Role-Based Access Control: Separate interfaces for administrators, issuers, and recipients for secure operations.
-
Backend
-
Blockchain Framework: Ethereum
-
Smart Contract Tools: Hardhat, Truffle
-
Programming Language: Solidity, JavaScript (Node.js)
-
Database: MongoDB
-
API Testing: POSTMAN

Navigate to the project directory:
cd Blockchain-based-microcredentialing-system -
Install dependencies for the frontend:
cd client npm install -
Deploy the frontend:
npm start -
Start the Hardhat node:
cd ../blockchain npx hardhat node -
Deploy the smart contract:
npx hardhat run scripts/deploy.js --network localhost
-
Credential Issuance: Administrators can issue micro-credentials by uploading details and assigning them to recipients.
-
Verification: Users or third parties can verify credentials by entering the credential hash or ID in the verification portal.
-
Audit Logs: Track all credentialing activities for transparency and accountability.
