A Modular Smart Contract Architecture for a Decentralized E-Learning Ecosystem Based on Purechain Blockchain

Abstract

Traditional e-learning and academic administration systems face persistent challenges, including credential fraud, inefficient verification processes, and a lack of transparency in financial aid distribution. This paper proposes a blockchain-integrated e-learning platform designed to address these issues by creating a secure, transparent, and automated ecosystem for academic records and financial aid. We present a hybrid architecture that leverages a high-performance permissioned blockchain, Purechain, to manage trust-critical functions while retaining conventional databases for dynamic content. The system is built around four modular smart contracts: IdentityRegistry, AcademicManager, EduToken, and ScholarshipFactory. The key innovation is the programmatic linkage between on-chain academic performance and automated scholarship disbursement, enabling a trustless, unbiased, and efficient financial aid model.
