A dynamic scalable blockchain based communication architecture for IoT

Abstract

The recent development of Blockchain based cryptocurrency technology has enabled a high level of trust and security for many applications in people’s daily life. Traditional Blockchain architecture can provide decentralized and trustworthy systems for financial services with persistency, anonymity, and auditability guaranteed. Internet of Things (IoT), as the next promising smart system, has the similar decentralized topology with Blockchain. However, deploying Blockchain in IoT system is still unpractical in many aspects. In this paper, we first point out the practical obstacles to deploy Blockchain topology in IoT system. Then a dynamic Blockchain based trust system is proposed to provide a dynamic and scalable communication architecture for IoT networks. We also present a case study to further discuss the security issues and provide future research directions.
