Software tool to store IoT device data onto a blockchain

Abstract

Certain IoT (Internet of Things) device data such as meteorological data are public goods, which are by definition, in high demand by a large user base. Accessibility to these datasets thrives with the use of blockchain technology. However, research has shown that due to the consensus mechanism of existing blockchain platforms, transaction approval delays and high transaction (gas) fees have been a challenge. This paper presents a software tool to integrate and store IoT device data onto a resource-efficient blockchain, with a decentralized proof of stake consensus mechanism, for faster and scalable application, with zero to near-zero transaction fees. • Some small Internet of Things (IoT) data like temperature, pressure, and humidity weather data can be stored on a blockchain. • Node-RED is a tool used by millions of users from large companies like IBM to small hobbyists. • The eosio-push node is custom built to take in IoT and transmit to a blockchain. • It can be run on raspberry pi. • It allows for customization of endpoints and message types. • The software is publicly available on NPM and receives between 10 and 50 downloads per week.
