Comparative Analysis of the Impact of Blockchain On Blockchain Based IoT Application

Abstract : Blockchain is a safe technology for transaction as it keeps the information safe that it is impossible to change, hack or cheat. blockchain is a digital mode of transaction that is spread across the entire network of computer systems in blockchain. IoT devices allows to send information or useful data in the blockchain to the persons that are inter- connected to each other using computer devices. Transaction is verified to stop discussion that each person or member in the blockchain is responsible for their roles. Using of blockchain with IoT reduces the cost as well the transaction is done with high security. So, we are going to do a comparative analysis of different IoT application on blockchain. And at last, we will come to know that which one application is giving more efficiency in terms of cost, manpower, adaptability, performance.

 EXISTING SYSTEM :

 ? We present a thorough literature review of existing blockchain application in the broad areas of IoT, Business, and Healthcare with their challenges and future opportunities. ? The article focuses on the existing literature review of the core blockchain architecture and its application areas, specifically, in Internet-of-Things (IoT), Healthcare, and Business. ? It also provides a Restful interface for existing applications to connect with the Blockchain network. ? The existing property registration systems are either manual or its on centralized which offcourse do not offer any restrictions to record tempering and transparency. ? We compare, categorize and analyze existing solution for using blockchain technology for healthcare.

 DISADVANTAGE :

 ? In this paper, we present introductory part of IoT enabled with blockchain, their key features, architecture layout, characteristic features of both the technologies, their futuristic solutions for different real-world problems, different communicational models etc. ? Due to heterogeneity of the IoT standards, protocol standards and IoT devices several problems get raised such as flexibility, lack of interoperability and scalability. ? These properties of IoT offers various problems and challenges related to trust, security, authenticity and privacy. ? Most of the work is being done on securing BIoT and hence many solutions to these problems are introduced by the researchers.

 PROPOSED SYSTEM :

 • Researchers have evaluated the challenges posed by BIIoT, identified solutions and proposed platforms for developing BIIoT applications for industry sector. • Based on blockchain model, researcher have proposed autonomous network management system for IoT network and IoT devices. • In the proposed ‘‘Standard Consortium’’ architecture, smart blockchain contracts control access, while providing accountability to both data owners and third parties. • However, due to the challenges of IoT infrastructure, a lot of research is being done on the topic of securing BIoT and more efficient solutions are being proposed. • It is lightweight blobkchain-based smart home framework proposed for security and privacy gains.

 ADVANTAGE :

 ? A service contracts includes documentations, service policies, QoS, and a service interface for monitoring and ensuring the QoS and the performance of IoT transactions. ? RTOS is selected on the basis of performance, functional need and security of the product. ? The main objective of IOTA is to resolve the performance concern and scalability with bitcoin by replacing its blockchain with Tangle as it is a system of nodes in which new transactions assures the preceding transaction. ? Decentralized Acyclic Graph whose aim is to solve the flexibility and performance concerns of the system. ? When the appliances demand for the high networking and high performance then this scalability is still an open issue for the blockchain.
