Traceability is now transformed into a fundamental viewpoint in supply chain administration, especially in safety-sensitive businesses like food. Consolidating blockchain innovation into food traceability can move forward supply chain administration, brand notoriety, buyer certainty, quicken item improvement, and diminish obligation dangers. This review employs expressive and substance examination to inspect distributions related to blockchain and internet of things-based supply chains and traditional supply chains. To completely inspect blockchain-based supply chains, four well-designed questions are being proposed and tended to, specifically, the esteem of incorporating blockchain into supply chains, the fascination of researchers to specific supply chain topics, the improvement of inquiring about strategies, and outline sorts in receiving supply chain applications of blockchain, and the sorts of businesses included in supply chains that use blockchain. The review considers points to examine the present-day standing, potential uses, and succeeding proceedings of this technology in supply chain administration. The objective of the study is to give an overview of blockchain-based supply chain investigation, along with an overview of the current state of literature, and highlight the advantages and troubles in incorporating this ideology. Chosen compilations were reviewed to create an abstract of supply chains utilizing smart contracts and blockchain. This paper provides valuable data to assist researchers and professionals to probe the relevant points to quicken the improvement of blockchain-based supply chains.
