Using Ethereum, IPFS, and the MERN stack, this project offers a transparent and safe blockchain-based examination system. The solution guarantees tamper-proof question paper management by utilising IPFS (via Pinata) for decentralised storage and Ethereum smart contracts. Instructors submit tests to IPFS, ensuring data integrity by storing their cryptographic hashes on the Ethereum blockchain. While MetaMask allows for safe user interaction and authentication, Hardhat makes it easier to design and deploy smart contracts on a testnet. A strong online application is powered by the MERN stack, with Node.js managing database functions and instructor authentication. Exam papers are safely retrieved by authorised superintendents, guaranteeing regulated access. Academic assessment integrity is improved by this decentralised method, which reduces the possibility of paper leaks and unauthorised changes while offering a scalable and effective substitute for conventional test systems.

摘要

Using Ethereum, IPFS, and the MERN stack, this project offers a transparent and safe blockchain-based examination system. The solution guarantees tamper-proof question paper management by utilising IPFS (via Pinata) for decentralised storage and Ethereum smart contracts. Instructors submit tests to IPFS, ensuring data integrity by storing their cryptographic hashes on the Ethereum blockchain. While MetaMask allows for safe user interaction and authentication, Hardhat makes it easier to design and deploy smart contracts on a testnet. A strong online application is powered by the MERN stack, with Node.js managing database functions and instructor authentication. Exam papers are safely retrieved by authorised superintendents, guaranteeing regulated access. Academic assessment integrity is improved by this decentralised method, which reduces the possibility of paper leaks and unauthorised changes while offering a scalable and effective substitute for conventional test systems.
