Verifico is a cutting-edge digital platform designed to securely store and verify student certificates using blockchain technology. This project addresses the critical issue of certificate forgery and the manual overhead associated with verification by implementing an automated, reliable, and immutable infrastructure using Hyperledger Fabric and IPFS (Interplanetary File System), which btw is really cool, checkout my paper based on this project on the IPFS network https://ipfs.io/ipfs/Qmf1WgXNH514mbA9gMDUPTTayMDXCJP127tzdTKtTD7Tgo
- Blockchain Technology: Utilizes Hyperledger Fabric, a private permissioned blockchain, to ensure the integrity and security of certificate data.
- Decentralized Storage: Implements IPFS to store certificates in a decentralized manner, enhancing accessibility and reliability.
- Automated Verification: Provides an end-to-end solution for the automated verification of certificates, reducing manual overhead and increasing efficiency.
- Secure Access: Ensures secure access to certificates using cryptographic keys and digital signatures.
This project showcases a comprehensive understanding and practical implementation of several advanced technologies and concepts, making it a valuable addition to any tech portfolio. By addressing real-world problems in the education sector, this project demonstrates the ability to create impactful solutions using blockchain technology.
Through this project, I have gained:
- In-depth Knowledge of Blockchain: Understanding the principles of blockchain technology, especially Hyperledger Fabric, and how to implement a private permissioned blockchain network.
- Decentralized Storage Systems: Experience with IPFS and how to integrate it with blockchain for secure and decentralized data storage.
- Smart Contract Development: Skills in writing and deploying smart contracts (chaincode) in Hyperledger Fabric using JavaScript.
- Backend and Frontend Development: Proficiency in developing backend services using Node.js and creating interactive front-end applications with HTML, CSS, and JavaScript.
- System Security: Implementation of various security measures, including JWT for user authentication and CORS for secure server communication.
-
Network Setup:
- Deployed a private permissioned blockchain network using Hyperledger Fabric.
- Configured various entities such as peers, orderers, and Certificate Authorities (CAs).
- Utilized Docker for containerized deployment and management of the network components.
-
Chaincode Deployment:
- Developed smart contracts (chaincode) to handle certificate transactions.
- Implemented lifecycle management for chaincode to ensure proper deployment and execution on the blockchain network.
-
Blockchain Interactions:
- Developed Node.js backend services to interact with the blockchain network.
- Implemented functions for user registration, certificate upload, and verification.
-
API Endpoints:
- Created RESTful API endpoints to handle various operations such as login, registration, and certificate verification.
- Utilized Express.js for API development and server management.
-
User Interface:
- Designed and developed an interactive web interface using HTML, CSS, and JavaScript.
- Implemented dynamic pages for different user roles (admin, college, verifier) to perform their respective operations.
-
Security:
- Implemented JWT for secure user authentication.
- Ensured secure communication between the server and clients using CORS.
- System Setup: Successfully set up and tested the system on an Ubuntu 20.04 environment with necessary dependencies.
- User Testing: Registered multiple users and uploaded certificates without system disruption.
- Performance: Verified that the system handles operations efficiently and securely, performing all required functionalities without errors.
- Cloud Migration: Moving the blockchain operations to a cloud platform like IBM Blockchain to handle high intake and avoid hardware exhaustion.
- Private IPFS Cluster: Implementing a private IPFS cluster to provide faster data access rates.
- Extended Functionalities: Expanding the system to support more operations for each actor and potentially scaling it to a full-fledged e-Learning platform.
