Consequences and Deliberations in Implementation of Blockchain and Internet of Things Integration

Abstract

Blockchain technology proposes security facilities to the Internet of Things (IoT). The things or objects used in daily life are connected to the internet to form IoT. The blockchain integral safety mechanism can deliver amenities, such as authentication, accessibility, integrity, secrecy, and authorization to the IoT applications. The uses of IoT applications are the dream turning into reality. But using this IoT still faces some challenges, mainly in the areas of security such as data consistency and reliability. The objects have interacted over the internet; they can also be supervised and controlled remotely. The use of IoT reduces time, manual work, tracking and money. With the evolution of IoT, it is essential to deliver more security for enormous amounts of data. Blockchain is a circulated network with the properties of integrity and secrecy. The blockchain maintains data security in the network of IoT. Here to discover the challenges associated with the combination of IoT and blockchain, a study is taken first, then a blockchain introduction is offered, followed by the Blockchain-based IoT requirements, demand and Quality of Service (QoS) discussed. Then, tasks faced while applying this blockchain-based IoT, such as plan, progress and deployment, are discussed. Then applications of blockchain-based IoT such as throughput, efficiency, latency, privacy, fork problem, smart contracts, legal issues, security, storage and proposed solutions are deliberated. Finally, upcoming research guidelines for the combination of IoT and blockchain are designated.
