Abstract
Pamateni ugovori kao vrsta digitalnog i računalnog izvršavanja neke njemu specificirane programske logike mogu poslužiti u raznim primjenama gdje sudionici ne vjeruju jedan drugome i potreban im je posrednik ili decentralizirani medij kao blockchain gdje nitko neće imati kontrolu, a pametni ugovor će se svejedno moći izvršiti. Pametni ugovori imaju usku funkcionalnost ako se samo bave onim što se događa na blockchainu, ali ako ih želimo povezati sa vanjskim svijetom potreban je entitet imena Oracle, koji služi kao poveznica sa informacijama iz vanjskog svijeta i operacijama koje se jedino mogu izvršavati izvan blockchaina (npr. slanje novca preko bankarskog sustava itd.). Mi smo koristili Chainlink decentraliziranu Oracle mrežu i njihovu tehnologiju da bi povezali pametne ugovore sa vanjskim svijetom. Kreirali smo mobilnu i web aplikaciju te ih povezali sa pametnim ugovorom kreiranim na testnom Kovan Ethereum blockchainu. Funkcionalnost tog pametnog ugovora je bila a registrirani korisnici mogu prelaziti zadane rute te biti sigurni da će njihovi lokacijski podaci nastali prilikom izvršavanja rute na siguran način obraditi i biti upisani na blockchain pomoću Chainlink čvorova tj. operatora koji su uz pomoć dodatkovnog programa (eng. Data Adapter) procesirali i obradili te lokacijske podatke.
Abstract (english)
Smart contracts as a type of digital and computer execution of some programmatic logic can serve in various applications where participants do not trust each other and need an intermediary or decentralized medium as a blockchain where no one will have control and the smart contract can still be executed. Smart contracts have narrow functionality if they only deal with what happens on the blockchain, but if we want to connect them to the outside world we need an entity named Oracle, which serves as a link to information from the outside world and operations that can only be performed outside the blockchain (e.g. sending money through the banking system, etc.). We used Chainlink’s decentralized Oracle network and their technology to connect smart contracts with the outside world. We created a mobile and web application and connected them to a smart contract created on the test Kovan Ethereum blockchain. The functionality of this smart contract was and registered users can cross default routes and be sure that their location data generated during the route will be safely processed and entered on the blockchain using Chainlink nodes, ie operators that are using an additional program (Data Adapter) processed and processed this location data.
