-------------------------------------------------------------***----------------------------------------------------------Abstract: This paper proposes a novel Learning Management System (LMS) built on the Ethereum blockchain to address these concerns. The system leverages MetaMask wallets for secure student authentication and utilizes smart contracts to automate grading and plagiarism detection, providing immediate feedback and enhancing learning efficiency. Robust security protocols ensure data integrity and prevent exam malpractices. This innovative approach fosters academic fairness, reduces instructor workload, and facilitates comprehensive student performance analysis, paving the way for a secure and efficient future of online education.
1.2 Components of BLMS: Blockchain: A distributed database that securely stores and verifies all exam data, including questions, answers, and grades. Think of it as a tamper-proof, public ledger accessible to authorized participants.
Keywords: Blockchain, Ethereum, MetaMask wallet, LMS, Smart Contracts, Auto-grader, Plagiarism Detection, Immediate feedback, Online exam, Security management. 1. INTRODUCTION

The traditional examination system, with its reliance on paper, pencils, and centralized administration, is facing a growing wave of challenges. Concerns about security breaches, data manipulation, plagiarism, and fairness are casting a shadow over the integrity of educational assessments. In this context, blockchain technology emerges as a transformative force, promising to revolutionize online examinations with its inherent advantages of decentralization, immutability, and transparency.
Ethereum: A popular blockchain platform that supports smart contracts, self-executing code used to automate grading, plagiarism detection, and other processes. MetaMask Wallet: A secure digital wallet used by students to access the exam platform and store their credentials. Smart Contracts: Automated programs on the blockchain that govern exam rules, grade answers, and manage data access.
Imagine a scenario: Students worldwide take an exam simultaneously on a secure online platform. Their responses are encrypted and stored on a distributed ledger, accessible only to authorized parties. An automated grading system powered by smart contracts instantly evaluates answers, providing immediate feedback. Plagiarism detection tools scan submissions in real-time, ensuring academic integrity. And the entire process, from question generation to scorekeeping, is governed by transparent, immutable records, fostering trust and accountability.
Auto-grader: An AI-powered tool embedded within smart contracts to provide immediate feedback on objective questions.
This is the power of blockchain-based online examinations. Let's delve deeper into the key components of this model and compare it to the traditional system.
