        abstract = {Agricultural supply chain often faces challenges in data manipulation, payment delay, and lack of trustworthiness. The challenges occur because of the absence of transparency, centralized record-keeping and reliance on intermediaries. Farmers get paid too little and even delayed payments for their crops and consumers cannot know the details of the crops including harvested time of the crop and quality. This creates damage for all the parties in the supply chain. To overcome this, we have built a blockchain-based supply chain monitoring system which uses decentralized ledgers to record the transactions and crop details. In this system each crop gets unique QR code when the farmer uploads the details of the crop. And each crop gets unique hash that is consistently gets verified against the smart contract, confirming the data’s destination. The system uses a hybrid storage system in which fewer sensitive data is stored in off chain SQLite database and the critical information like transaction details are stored in Blockchain. Whenever transactions happen a unique hash is generated which helps to store the transaction details in a tamper-proof manner and links blocks within the blockchain. Payment is integrated using RazorPay in testing mode which is a secure payment gateway in which the parties can make payments. With the QR code the customers can know the details of the crops. The system promises enhanced data integrity, improved traceability, reduces middlemen participation and provides full transparency of the supply chain.},
