Blockchain-Based Agri-Food Supply Chain Management

Abstract

AbstractAdvancements in the supply chain involving automatic networks are becoming a significant wellspring of advantages in the contemporary environment. Consumers on the other hand are emphasized in the quality of food products. The proliferation in production and supply of unhealthy, preserved, and zero nutritional value food supply has completely restored the center around the well-being, quality, and approval of high nutritional value food products in the food supply chain. The booming concerns about the third-party involvement, food quality, user privacy, and transparency calls for an effective, reliable, and secure system that tackles all these existing issues. Blockchain is advancing as a decentralized and more secured technology that could reinstate the contribution of the third party and also verify the transactions within the network. The ultimate aim was to implement a blockchain based to keep a track on the food quality and the emergence of the supply chain. A Quick Response code, which contained the location of the case, was a reference to the virtual item in the network. In order to achieve transparency, interaction of all the actors within the system is necessary. Peers of the blockchain system validate each and every transaction that is product related. For every transaction, the product ownership was modified. The reputation of farmers with their products was stipulated based on token-based mechanisms. A confirmation demand with respect to the items can be put, and the farmers can be benefited with notoriety tokens for each affirmation by peers. In order to distinguish or identify every item inside the supply chain, a unique Quick Response code has been used to improve both security and productivity for area-based assistance in vehicular social networks (VSNs), because of its inborn decentralization, obscurity, and trust properties. Sadly, the current methodologies either need powerful verification, which is helpless against man-in-the-middle attack, or require an online certificate authority (CA), where regular communications with asset compelled vehicles are required. To address these challenging issues, in this paper, a lightweight threshold CA for public blockchain along with a privacy preserving location-based service is proposed.KeywordsBlockchainSupply chainSmart contractConsensus algorithmVehicular social networks (VSNs)
