This study highlights the utility of blockchain, the Internet of Things (IoT) and FinTech in cold chain/post-harvest supply chain. Blockchain technology will enable the stakeholders in a post-harvest supply chain to track and trace the level of inventory, smart contracts, prices, associated costs, and scale of transactions at any stage in the supply chain. The IoT infrastructure linked with cloud computing will assist the blockchain ecosystem with time–temperature regulation, traceability, and decision-making. The practice of blockchain at decentralized levels linked with the global market will develop marketplaces and exports with enhanced information visibility, reduced spoilage ratio, and boost business prospects and the economy. Accepting and implementing blockchain and IoT will improve total supply chain profitability and reduce price spread.
