A Supervision System on Organic Products Supply Chain Based on Blockchain Technology

Nowadays, based on the spreading of information technology, food consumers especially organic food increasingly want to be informed about the history of food products that they are buying. They want to know about the origin of food, the condition of storage, transporting, etc. besides the information are printed on the packages. In this paper, we are proposing a back and forth supervision system on organic products supply chain based on blockchain technology to ensure data integrity and allow data tracing. The proposed system as a decentralized and secure infrastructure database improves food security and safety, and reduces fraud by verifying the quality and the origin of the products throughout the entire their agricultural supply chain. A unique Quick Response code was used to identify each product within the supply chain. Automated protocols on validation each transaction and events related to a product by peers of the Blockchain system enable data transmitted on the network to be verified and stored immutably and minimizing the risk of data corruption.
