“…In the AgriFood supply chain, IoT devices and sensors have been used during agricultural production [7], disease management, smart harvesting [8], storage [9] and transport [10] of food, to provide a variety of important information about vegetation, soil, nutrients, used fertilizers [11], identification, location and status of food [12], state of the environment in which the food is stored or transported, these data are commercially sensitive, often provided to consumers and data buyers, but providing them without leaking confidential data of the proprietary, poses a greater challenge [13]. In addition, the devices used have special characteristics such as limited performance, mobility and distributed deployment [14] [15], making it difficult to guarantee security, privacy, and write access control of sensors and read access control of users in Internet of Things networks. Blockchain technology, as a distributed, decentralized and immutable ledger, is a potential solution to address the limitations of current IoT networks.…”
