This project paper discusses the use of blockchain technology in a crowdsourcing system for the creation of question papers for online and offline exams. The system is designed to provide a diverse set of questions, promote transparency and inclusivity, and automate the generation of question papers. The paper outlines the benefits and drawbacks of traditional question paper setting and crowdsourcing and proposes the use of blockchain technology to achieve decentralization, transparency, and security. The project was developed using the Solidity programming language, which is a high-level programming language used for writing smart contracts on various blockchain platforms. The development frameworks used were Hardhat and Remix IDE, which provide a set of tools for building, testing, and deploying smart contracts. Furthermore, the project was deployed on the Polygon blockchain, which is a Layer-2 scaling solution for Ethereum. This blockchain offers faster transaction processing times and lower fees compared to the Ethereum Mainnet, making it an attractive option for deploying decentralized applications. The Graph Protocol's Subgraph hosted service is used to index the blockchain data and provide a user-friendly interface for querying and analyzing the generated questions.
