Abstract

Namen tega diplomskega dela je bil analizirati prednosti, slabosti in notranje delovanje platforme Hyperledger Fabric, ki je platforma za izgradnjo konzorcijskih omrežij na osnovi veriženja blokov. V ta namen je bil izdelan preprost prototipni sistem interneta stvari, na katerem je bila izvedena študija. Služil je kot način za predstavitev tehnologije, pa tudi za prikaz njenega delovanja v praksi. Z vzpostavitvijo prototipnega sistema interneta stvari smo si podrobneje ogle- dali postopek vzpostavitve konzorcijskega omrežja veriženja blokov in njegovo delovanje. Senzorji so bili sestavljeni iz preoblikovanih senzorjev kakovosti zraka, ki so bili opremljeni z Wi-Fi čipi, da smo jim omogočili omrežno povezljivost. Ti senzorji so nato pošiljali odčitke v omrežje računalniškemu vozlišču v bližini, ki je bilo sposobno obdelovati in prenašati podatke v verigo blokov. Vzpostavili smo dve organizaciji, tako da smo lahko simulirali sodelovanje v omrežju. Prva orga- nizacija je imela v lasti senzorje in je zapisovala njihove odčitke v verigo blokov, v zameno za plačilo pa je te odčitke organizacija 2 lahko brala.

Secondary title:	ǂA ǂdecentralized IoT application using Hyperledger Fabric technology
Secondary abstract:	The purpose of this thesis was to analyse the advantages, disadvantages and the inner workings of the Hyperledger Fabric platform, a platform used to build consortium blockchain networks. For that purpose a simple proof of concept IoT system was designed on which the study was carried out. It served as a way to present the technology, but also to see how it works and operates in practice. By setting up the proof of concept IoT system we got a closer look at the process of creating a consortium blockchain network and how it operates. The system itself consists of remodeled air quality sensors which were fitted with ESP8266 Wi-Fi chips to give them network connectivity. These sensors sent their readings to a computer node nearby that was capable of processing and commiting the data to the blockchain. We set up multiple organizations where one owned the sensors and the other one provided access to the sensor data for a fee. We setup a simple dapp that could read and pay for the sensor data.
