Blockchain-Based Academic Credential Verification for ABV-IIITM Gwalior

Features • Architecture • Getting Started • User Guides • API Reference

📋 Overview

PARAM (Portal for Academic Records and Management) is a comprehensive, blockchain-based academic credential management system designed for universities and educational institutions. Built for ABV-Indian Institute of Information Technology and Management Gwalior, PARAM enables tamper-proof issuance, verification, and sharing of academic credentials including semester results, transcripts, and degree certificates.

Why PARAM?

Tamper-Proof: Academic credentials are minted as NFTs on the blockchain, ensuring immutability
Instant Verification: Employers and institutions can verify credentials in seconds using a public link
Zero Student Friction: Students never need wallets or crypto knowledge — credentials are issued to institute-managed wallets
Audit Trail: Every action is logged with immutable audit records for compliance
Multi-Level Approvals: Configurable approval workflows ensure proper oversight before credential issuance
