Victor Roman, Joaquín B. Ordieres-Meré · 2018
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.
