    A Unique Web 3 Product-NFT Usage in Healthcare
    (IEEE, 2025) Unozkan, Huseyin
    Non-fungible tokens (NFTs) have gained immense popularity and value in recent years. After the Web 3 revolution, many new products have been constructed based on smart contracts or powerful software agreements. One of the most exciting products of Web 3 is NFT, with their increasing popularity, high volatility, and significant price movements making them popular in trading activities. Although many people, investors and researchers perceive NFTs as a trading product, the smart contract and metadata, both of which make up of NFT structure, offer valuable support for the big data storage and processing fields. In recent years, researchers have proposed different uses of NFTs in healthcare systems to improve the quality of services by using NFTs' versatile data storage architecture. In this study, the capability of NFTs in the storage of health data is investigated, the usage and usage proposals of NFTs in health are examined, and probable usage areas in health sciences are evaluated. The uniqueness of this study is, using NFTs as the dead parental data storage in which the metadata does not need to be mitigated, but the stored data is very valuable for doctors to assess the genetic illnesses comes from parental DNAs.

    Decentralisation as Resistance: Web3’s Potential in Countering Digital Censorship and Redefining Cyber Sovereignty
    (Eotvos Lorand Tudomanyegyetem, 2024) Eldem, T.
    The Internet, initially celebrated as a bastion of freedom and openness, is increasingly becoming a domain of control, surveillance, and regulation by both states and private entities. The rise of state control and regulation of the Internet, along with the private sector’s expanding control over information, poses significant challenges to the ideals of freedom and openness that once defined the Internet. This article examines the transformation in Internet governance from a state of minimal regulation to a heavily controlled environment by both governments and corporations and explores how the blockchain technology and decentralised architecture underlying Web3 promise to redefine Internet governance and resist censorship. Through a mixed-method approach that synthesises insights from computer science, political science, and legal studies, the paper argues that public blockchains challenge Internet Corporation for Assigned Names and Numbers’ (ICANN) traditional control over DNS and significantly reduce the ability of centralised entities to exert control over content and communication, thereby enhancing freedom of expression and resisting censorship. The ability of Web3 to fully realise this potential is, however, dependent on overcoming complex technical and regulatory challenges. © 2024, Eotvos Lorand Tudomanyegyetem. All rights reserved.

    Transaction Types in Cryptocurrencies
    (Institute of Electrical and Electronics Engineers Inc., 2024) Uysal, T.; Unozkan, H.
    The cryptocurrency ecosystem has witnessed an explosive growth, and this study delves into the mechanisms that fuel this expansion. Focusing on airdrops, staking, farming, and coin burning, the research analyzes a vast dataset of transactions from the Ethereum and Binance Networks. This analysis sheds light on the strategic use of these tools by highlighting transactions that engage users and distribute rewards (e.g., airdrops, staking). Furthermore, the study investigates farming as a method to enhance market efficiency by providing liquidity, and coin burning as a strategy to manage token supply and potentially increase value through scarcity. While effective utilization of these mechanisms can bolster token value and project success, regulatory challenges remain. Ultimately, this study aims to raise public awareness of cryptocurrency transaction types and the associated risks. Although many researchers have studied illicit flows on cryptocurrency transactions, in literature we haven't confronted with any study regarding transaction types. By analyzing over 107 million transaction records, the research presents the distribution of these transaction types. With the analysis of the transaction types, the definitions of them, the statistical outputs from the more than 107 million transaction records from ERC20 and BEP20 blockchain systems and the analysis of some specific token types such as Pancake Swap and Shiba, this research is the first study to present an academic approach with statistical analysis. This study can provide investors with knowledge that safeguard them from the potential pitfalls of cryptocurrency transactions. Also, this study presents some basic statistics so as to understand main patterns of different types of transactions. © 2024 IEEE.
