Abstract

Lanci opskrbe hranom vrlo su složeni, postoje određeni zakoni, standardi kao i centralizirani načini praćenja sljedivosti hrane no to nije dovoljno da bi se izbjegla izbijanja bolesti i pronašli njihovi uzroci. Jedno od mogućih rješenja ovog problema je primjena tehnologije distribuirane glavne knjige koja nam pruža decentraliziranu i sigurnu mrežu, kao i transparentan i trajan način zapisa podataka u glavnu knjigu. Također potrebno je potaknuti sve dionike lanca na digitalizaciju strojeva i primjenu senzora kojima bi prikupljali podatke o uzgoju i skladištenju hrane, a korisnik mora biti u mogućnosti ovakvo rješenje koristiti na jednostavan i brz način. Ovaj rad koristi distribuiranu glavnu knjigu IOTA koja je namijenjena uređajima interneta stvari, a sve podatke zapisuje u strukturu usmjerenog acikličkog grafa zvanog Tangle. Još jedna od značajki IOTA-e je MAM protokol koji dionicima lanca omogućuje zapis podataka u javne, ali i ograničene kanale kojima se ne može pristupiti bez autorizacijskog ključa. Koristeći navedene značajke IOTA-e, u sklopu rada implementirano je rješenje praćenja sljedivosti u lancu koji se sastoji od farmera, proizvođača i prodavača. Svaki od dionika svojim poslužiteljem u Tangle zapisuje podatke vezane uz proizvod, korijeni transakcija zapisuju se u QR kod na proizvodu, a korisnik kod može skenirati razvijenom aplikacijom CQRN i na pregled dobiti sve informacije koje su dionici zapisali u Tangle.

Abstract (english)

Food supply chains are very complex, there are certain laws, standards as well as centralized ways of monitoring food traceability, but this is not enough to avoid disease outbreaks and to find their causes. One possible solution for these problems are the use of distributed ledger technologies that provide us with a decentralized and secure network, as well as a transparent and permanent way of writing data to the ledger. It is also necessary to encourage all stakeholders to digitalize their machines and to use sensors which would collect data about food cultivation and storage. This thesis uses the IOTA ledger technology, which is intended for Internet of Things devices and records all data in structures of directional acyclic graphs called Tangle. Another feature of the IOTA is MAM protocol, which allows chain stakeholders to write data to public, but also restricted channels. Using the mentioned features of IOTA, as part of the thesis, a traceability solution was implemented for a chain consisting of farmers, producers and sellers. Each stakeholder writes product-related data to the Tangle, transaction roots are written to the QR code on the product, and the user can scan the code with the developed CQRN application to obtain all information which stakeholders have written into the Tangle.
