[WiP] IoT Blockchain Technologies for Smart Sensors Based on Raspberry Pi

Abstract

The aim of this paper is to propose an Internet of Things system that collects, sends, stores, and publishes relevant data using a Raspberry Pi as the smart sensor. Distributed Ledger Technologies (DLT) from BigchainDB and IOTA are used to store data in a blockchain-like database, and to publish a temporal statistic data summary respectively, in addition to store the data streams in a SQL database. The collection, storage, and publication of the data is free and almost instantaneous. This system can become a source of evidences to different types of stakeholders all around specific businesses getting benefits from keeping the level of trust along its value chain.
