📘 Academic Transcript Verification System

Overview

This project is a full-stack academic transcript management and verification system designed to improve the integrity, authenticity, and verification of academic records. It leverages blockchain technology and distributed storage to prevent tampering and enable verifiable transcript validation.

The system allows authorized institutions to issue academic transcripts and third parties to verify them without relying on a centralized authority.

Key Objectives

• Prevent transcript forgery and unauthorized modification
• Enable transparent and verifiable academic records
• Separate storage of sensitive data from verification logic
• Demonstrate secure system design using modern technologies

System Architecture

The project follows a modular architecture:

• Frontend (Client):
  User interface for issuing and verifying transcripts.

• Backend (Node.js / Express):
  Handles application logic, user management, and interaction between frontend, blockchain, and storage layers.

• Smart Contracts (Ethereum / Truffle):
  Stores transcript hashes and verification logic on the blockchain to ensure immutability.

• IPFS (InterPlanetary File System):
  Used to store transcript documents off-chain while preserving integrity through cryptographic hashes.

Technologies Used

• Blockchain: Ethereum, Truffle
• Backend: Node.js, Express
• Smart Contracts: Solidity
• Storage: IPFS
• Frontend: JavaScript (client application)
• Other Tools: Web3.js, Git

Security Considerations

• Transcript documents are not stored directly on the blockchain to reduce exposure and cost.
• Only cryptographic hashes are recorded on-chain to ensure data integrity and tamper resistance.
• Verification relies on hash comparison, preventing unauthorized modification of transcripts.
• The system design emphasizes separation of concerns and minimized trust assumptions.

Current Status

🚧 In Progress

• Core architecture implemented
• Smart contracts deployed locally
• Backend and IPFS integration functional
• Frontend features under active development

Further improvements include enhanced authentication, role-based access control, and deployment to test networks.

What This Project Demonstrates

• Full-stack system design and integration
• Practical use of blockchain beyond theory
• Secure data handling and verification concepts
• Ability to work with distributed systems and modern infrastructure
