Problems of Normative and Legal Regulation of the Process of Applying Blockchain Technology in the Financial System of Ukraine

The purpose of the article is to study the theoretical and applied aspects of identifying the problems of normative and legal regulation of the process of applying blockchain technology in the financial system of Ukraine. The results of the conducted research allow us to assert that blockchain technology is a qualitatively new tool for carrying out financial transactions and strengthening the financial system of Ukraine, the essence of which is the creation of a decentralized database consisting of blockchains capable of preventing deliberate actions, the subject of which is data falsification and their chronological records for the purpose of tracking and controlling transactions. The important role of blockchain technology in the financial system of Ukraine has been established, which is manifested in the modernization of the processes of moving funds, making cross-border payments, and the functioning of cryptocurrency. The excessive weakness of the legislative and normative and legal regulation of the process of applying blockchain technology in the financial system of Ukraine was revealed, which is situational and fragmentary in nature and cannot fully regulate the organizational and legal mechanisms of its effective application in the implementation of financial transactions. Detailed studies made it possible to substantiate the need for the formation of a national system of normative and legal regulation of the process of applying blockchain technology in the financial system of Ukraine, as a number of its problems were identified, in particular, the low level of the country's provision of digital technologies and the absence of high-speed Internet, as well as the high cost of using technologies and energy for maintenance of financial transactions in the blockchain system. On the basis of comparative studies of the USA, Great Britain and Ukraine, it has been proved that the development of blockchain technology is significantly dependent on the level of socio-economic development of the country and its ability to regulate problematic aspects arising under the influence of modern challenges and dangers at the legislative level. The need to adopt the Law of Ukraine "On Virtual Assets" is proposed, which will partially solve the most acute problems by unifying norms and creating an organizational and legal mechanism for regulating the process of applying blockchain technology in the financial system.
