Robust Food Supply Chain Traceability System based on HACCP using Federated Blockchain

Abstract

In this fast growing world, everything needs to change and upgrade with the technology to survive in this rapidly changing environment. The Food Supply Chain system is one of them. In traditional supply chain management functions, it is hard to manage the flow of traceability information of products timely and effectively among upstream to downstream stakeholders.This gap in the flow of information and untrusted traceability of product causes to generate food contamination hazards and also increasing the network of modern FSC systems is still challenging to provide quality, privacy, and integrity of traceability mechanism. HACCP and Blockchain-based FSC provide various functions to enhance the FSC process such as traceability,transparency, security among all stakeholders. In these functions, some most important functions of the Food Supply Chain system are traceability, amount of data sharing, and privacy of data of products among stakeholders.
 In this paper, we are going to provide an Enhanced Food Supply Chain Traceability system based on Federated Blockchain with HACCP using smart contracts. This model will manage by pre- selected leaders’ nodes. These leaders’ nodes have the right to control the action of middle nodes and lower nodes. The amount of data sharing can also be controlled by the leaders’ nodes.So, any particular transaction is restricted to perform by middle and lower nodes because the Federated Blockchain is partially decentralized. This model overcomes the issue of privacy concern which remains unsolved by blockchain-based FSC and makes a better and enhanced Federated Blockchain-based FSC traceability system.
