Distributed Land Registry solution for Croatia using blockchain technology. All users have read-only access to the blockchain data, but land owner nodes have write access for managing their own land registry data using a smart contract written in chaincode with TypeScript and Go. All nodes in the network are connected to a Kafka cluster for message queuing and a CouchDB cluster for storing the blockchain data.
Developed an academic project for the university involving a web application for managing land registry data and a distributed blockchain-based database for land
Implemented the solution on a permissioned Hyperledger Fabric network, with Hyperledger Explorer for monitoring, using Node.js, React, and Express API for the web application
Modeled land as a digital asset on the blockchain with unique ID, owner, area, location, and other data

Decentralized oracle for requesting cryptocurrency market prices. This project implements the possible solution to 'oracle problem', which is one of the biggest problems facing DLT systems based on smart contracts. Since the concept of reliability in DLT systems is not adequately solved by cryptographic security, we arrive at the concept of data truthfulness as a new property needed to characterize reliable, decentralized systems. A decentralized oracle makes DLT useful by allowing the entry of non-confidential data into the system in a decentralized manner, without relying on a central entity, which eliminates a single point of failure.
Developed an academic project as part of my master's thesis, involving a smart contract for requesting cryptocurrency market prices and a web application for managing the oracle
Implemented a smart contract in Solidity, utilizing Chainlink for external API requests, and created the web application using Node.js, React, and Web3.js for smart contract communication
Utilized Linkpool for managing oracle nodes and used LINK tokens for compensating oracle nodes for their work
