Blockchain and FinTech Research (BlockFin)

A diverse group of researchers at FIIT are working on a range of Blockchain academic and industry-driven research projects in a means to push further the technical development and innovation of the endless applications of Blockchain.
Current research projects include: connection to IoT platforms and it's usability, distributed systems, data mining and machine learning, anti-money laundering techniques, scalability and resiliency, smart contracts, non-fungible tokens (NFTs), blockchains interoperability, voting and election systems based on blockchain, privacy and security in blockchains and cryptocurrencies, asset sharing blockchain platforms, metaverse projects, decentralized finances (DeFi), and applications of blockchain into normal life.

The vision of the group lays in approaching Internet of Value in a horizon of 5 to 10 years and further empowering blockchain technology usage in society, actually, especially metaverse.

His research focus lies in Zero-Knowledge Proofs, scalable transparent argument of knowledge (STARK), and succinct non-interactive argument of knowledge (SNARK). He has been researching blockchain technology since 2018 with research focus firstly in blockchain-based car-sharing platforms, afterwards in universal asset sharing platforms and composability non-fungible tokens. He also has practical experience in building an open-source NFT virtual gallery which enhances the idea of ownership and IP in the digital ecosystem. Nowadays he focuses on metaverse research.
