Abstract
In Tunisia, one of the major problems in the olive oil industry is marketing. Several factors have an impact such as quality, originality, lobbying, subvention, and Extra Virgin Olive Oil certification. The major issue is still traceability of the production process to ensure that food provenance is always guaranteed. Such fine-grained traceability can be achieved by applying Blockchain technologies. Blockchain can be used as a solution that should bring visibility to the oil supply chain. It is proposed to guarantee the veracity of the product’s information at the different stages. We use the Ethereum Blockchain to program the smart contract. This smart contract allows us to configure our system to follow the manufacturing process of olive oil from the farmer through the oil factory to the customer. In this paper we present a general-purpose approach for the oil supply chain management, proposing a system that can be configured for productions. The primary purpose is to provide a methodology to facilitate and make more efficient the development of such applications. It is based on general smart contracts and apps interacting with the same smart contracts. We use IoT to configure sensors. These sensors are the data source for the supply chain process.
