Model of Controlled Environment based on Blockchain and IoT

In the era of Industry 4.0, automated remote monitoring of environmental conditions is based on the use of IoT sensors controlled by various wireless technologies. Registering the moment of occurrence of unwanted and unexpected events is extremely important, both for taking adequate actions to limit the damage and for proving the responsibility of certain employees, but also for presenting an insurance claim to the insurance company with irrefutable evidence. This paper presents a model and solution based on HyperLedger blockchain and IoT sensor network integrating BLE, LoRa and ZigBee technologies. The presented studies prove the applicability of the proposed model and the advantages it offers - trust, transparency, security, visibility and role-based access to all participants in the business network.
