Blockchain technology is increasingly gaining attention in various agricultural applications, addressing the diverse needs within the agricultural ecosystem.These applications provide provenance traceability, increase food safety transparency, facilitate IoT-based food quality management, and boost contract interchange and transaction efficiency. Numerous unreliable parties, including small-scale farmers, food processors, logistics firms, distributors, and retailers, are involved in the intricate farm-to-fork supply chain. Because of this intricacy, agricultural management systems must strike the ideal balance betthis en integrity and efficiency. An extensive overview of blockchain technology's methods and uses in the agriculture industry is provided in this article. To provide readers a basic grasp of how blockchain works, the paper first describes the technical aspects of blockchain, including data structures, cryptographic techniques, and consensus mechanisms. It then goes on to classify and examine current blockchain applications for agriculture, showing how these technologies are being applied to solve issues facing the industry. Furthermore, this ll-known blockchain networks and smart contracts are covered, demonstrating how practitioners use these resources to create agricultural solutions. The study also lists the main problems that agricultural systems face and looks into possible fixes. Lastly, a case study featuring an enhanced food supply chain model is provided, illustrating how blockchain technology can be successfully applied in the post-COVID-19 economy.
