Abstract
This paper proposes a novel approach to plagiarism detection using public blockchain technology to ensure academic integrity. By leveraging immutable ledgers, the system securely stores document hashes, timestamps, and metadata, allowing verifiable originality and tamper-proof evidence. Traditional plagiarism detection methods fall short in tracing modified content, whereas blockchain enables decentralized, trustless verification and enhanced transparency. The study incorporates smart contracts and content hashing while addressing technical, ethical, and legal challenges. Case studies demonstrate the system's feasibility for detecting plagiarism in academic environments, promoting a fair and trustworthy educational ecosystem.
