Brief Survey and Testbed Development for Blockchain Based Internet of Things

Abstract

Blockchain and the Internet of Things are uprising in today’s technology world. Internet of Things or IoT are the devices with unique identifiers that share data or information over the internet whereas, Blockchain is a peer to peer network with a distributed ledger that contains a list of blocks that are linked together by cryptography. Fascinated and motivated by blockchain and Internet of Things (IoT), this thesis provides a review on blockchain based internet of things and also introduces a working testbed that integrates the two together. It also uses IoT device to invoke transactions into the blockchain. The reasons behind combining of blockchain and IoT is because the present centralized architecture won’t hold the exponentially growing use of IoT, blockchain implementation can reduce cost and moreover, decentralization will remove the bottleneck from the centralized server
