  The main aim of the paper is to create a trust and transparency in the food
supply chain system, ensuring food safety for everyone with the help of
Blockchain Technology. Food supply chain is the process of tracing a crop from
the farmer or producer to the buyer. With the advent of blockchain, providing a
safe and fraud-free environment for the provision of numerous agricultural
necessities has become much easier. Because of the globalization of trade, the
present supply chain market today includes various companies involving
integration of data, complex transactions and distribution. Information tamper
resistance, supply-demand relationships, and traceable oversight are all
difficulties that arise as a result of this. Blockchain is a distributed ledger
technology that can provide information that is resistant to tampering. This
strategy can eliminate the need for a centralized trusted authority,
intermediaries, and business histories, allowing for increased production and
security while maintaining the highest levels of integrity, liability, and
safety. In order to have an integrity and transparency in food supply chain in
the agricultural sector, a framework is proposed here based on block chain and
IoT.
