The Internet of Things (IoT) is an emerging technology. It enables users and various IoT-enabled devices to be linked across the IoT network in order to exchange their data and resources, which would result in a more relaxed and connected lifestyle. There are still several challenges facing the new centralized IoT network. For illustrative purposes, the method for computing all connected nodes within the network relies on a centralized server. The centralized IoT model prompts a single point of failure when the central server is offline. The centralized IoT model is a clear target for privacy and security issues, as a centralized system completely handles all IoT data of several connected devices. The implementation of the Quorum Blockchain Network (QBN) with the InterPlanetary File System (IPFS) on the IoT network will solve these problems. It provides an unchangeable ledger that would ensure the reliability of transactions between linked nodes on a distributed blockchain network thereby replacing the central authority. This paper aims to propose a distributed IoT data store and a decentralized IoT network using a QBN model with an IPFS protocol.
