Ethereum Based IoT Architecture

Abstract

Internet of Things (IoT) is expanding exponentially due to the manufacturing of cheaper electronics and high-speed communication. Blockchain technology has paved way for the introduction of digital cryptocurrency called bitcoin. The blockchain is one of the four main technologies that have enabled cryptocurrency. Conceptually blockchain is a distributed digital ledger that stores data in blocks, which are cryptographically linked with the previous blocks. This makes blockchain immutable. Blockchain has gained its popularity in the scientific community with the success of bitcoin and ever since researchers are trying to adopt this technology to other areas in order to solve problems beyond the smart sectors like Internet of Things (IoT), supply chain and so on. In our research work, we adopt blockchain in IoT and implement ethereum based IoT architecture for securing the IoT network. We have implemented a two-node ethereum network where transactions are made at the expense of ether and each transaction is verified by the miner using the smart contract written in the ethereum network.
