| Abstract [eng] |
The work consists of: 79 pages, 12 figures, 9 tables, 124 literature sources and 8 appendices. In decentralized finance, the manifestations of fraud, fraud and crime have also increased due to the special characteristics of decentralized finance, such as pseudonymity and the absence of intermediaries. In this master's thesis, it was chosen to examine these crimes, their characteristic features, frequency, choose the most popular and the most damaging crime, investigate it and present ways to protect yourself from it. The paper examines in detail and selects the "Rug pull" decentralized finance financial crime that became popular in 2021, during which investors can lose all their invested funds. The aim of the work - after examining the theoretical aspects of financial crimes in the decentralized financial ecosystem, perform an assessment of financial crimes in the decentralized financial ecosystem. Methods used in the work: examination of scientific literature sources and information systematization, comparative analysis, inferential statistics, T.test, Pearson's correlation methods. The conclusions of the work respond to the tasks set during the master's work: highlighted the relevance of investigating financial crimes in decentralized finance and "Rug pull" financial crime, presented a typology of "Rug pull" financial crime, developed a methodology for comparing decentralized finance financial crimes and virtual currencies, evaluating and recognizing "Rug pull" financial crime, and a model for to protect against "Rug pull" decentralized finance financial crime, development, financial crime activity compared to Ether value in selected time periods, investigated how Ether price variation in selected time periods correlates with investor transfers to Rug pull financial crime tokens, finally developed a model to protect against Rug pull financial crime. Proposals were also formulated: it is suggested that investors use the model created in the master's thesis, which allows checking whether the token is related to the financial crime of decentralized finance "Rug pull", in order to facilitate access to structured information about decentralized finance, it is proposed to purchase third-party analysis services, and it is also proposed to implement an automated security system in the software and systems where tokens are traded, it is finally proposed to examine other financial crimes in the decentralized finance ecosystem and after examining the characteristics of those crimes and after evaluating the results presented by other scientists, create models for protection against financial crimes of decentralized finance. |
