A Zero-Knowledge Proof-Enabled Blockchain-Based Academic Record Verification System

Area of Science:

• Computer Science
• Information Security
• Blockchain Technology

Background:

• Academic credential fraud undermines global markets and trust in qualifications.
• Current verification systems often lack robust security, privacy, and efficiency.
• Centralized authorities create single points of failure and data privacy risks.

Purpose of the Study:

• To introduce ZKBAR-V, a novel Zero-Knowledge Proof-Enabled Blockchain-Based Academic Record Verification System.
• To establish a privacy-preserving, immutable, and secure framework for academic credential management.
• To enhance the integrity and global mobility of academic qualifications.

Main Methods:

• Leveraging zkEVM smart contracts on a blockchain infrastructure for data-private verification.
• Integrating Decentralized Identifiers (DIDs) for standardized, decentralized identity management.
• Utilizing a dual-blockchain approach for separating public and private information and employing the Interplanetary File System (IPFS) for secure, decentralized storage.

Main Results:

• Demonstrated secure transaction management and enhanced privacy capabilities.
• Achieved cost reductions compared to traditional Ethereum mainnet solutions.
• Validated the system's scalability, adaptability, and robustness in comprehensive testing.

Conclusions:

• ZKBAR-V offers a trustworthy and efficient verification system for academic credentials.
• The system significantly enhances credential integrity and promotes global student mobility.
• Combines blockchain, DIDs, and decentralized storage for a comprehensive solution.
