Blockchain is an emerging technology, nowadays looked at it as a solution for most of the security issues of any system. It is a breakthrough to the traditional way of developing the applications which provides robust features in security, sharing the information, and immutability. Blockchain is digital ledger, and every transaction is considered as one record. This data is stored in encrypted format, and the series of records are linked in such a way that any tampering of the data is close to impossible. This literature study is focusing on the usage of blockchain in agriculture domain in supply chain. Researchers have provided various innovative solutions to improve on traceability in supply chain of food, fruit, vegetables, and seeds. The study of literatures helps to understand the new technical concepts that make blockchain as an effective solution, for e.g., BigchainDB to avoid decentralized database issues, use of activation key for authorization, and combination of blockchain and SQL database to improve the performance and efficiency. It is also observed that the combination of IoT with blockchain will bring error-free data entry and easy to use it improving traceability in the supply chain. This paper aims to understand all these concepts from various studies. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
