The Library Management System (LMS) is a Solidity-based smart contract deployed on the Ethereum blockchain that enables a decentralized and transparent way to manage library operations. The contract allows the librarian, acting as the system owner, to add, update, and remove books from the catalog, while readers can securely borrow and return books. Every action—such as adding a book or borrowing one—is permanently stored on the blockchain, ensuring full transparency, accountability, and an immutable record of all library transactions.

The mission of this project is to demonstrate how decentralized technology can modernize and secure everyday systems like library management. By combining transparency, immutability, and controlled access, the LMS aims to create a trust-driven environment where both librarians and readers can interact without fear of data loss or manipulation. It serves as a practical example for beginners to understand Solidity development and the power of blockchain-based record-keeping.
Traditional library management systems rely on centralized databases, which can lead to issues such as loss of records, unauthorized changes, data manipulation, or lack of transparency in book availability and usage. Users may not always trust the accuracy of the system, and librarians face challenges in maintaining consistent, tamper-proof records of borrowing and returning activities.
The Library Management System leverages blockchain technology to create a secure, tamper-proof, and fully transparent library platform. Only the contract owner can add new books, ensuring controlled catalog management, while each book entry contains structured data such as title, author, and available copies. Users can borrow books as long as copies exist and return them later, with every action being permanently recorded on-chain. The system emits events whenever a book is added, borrowed, or returned, allowing real-time tracking and seamless integration with front-end applications.
