USE OF NON-FUNGIBLE TOKENS AND BLOCKCHAIN TO DEMARCATE ACCESS TO PUBLIC REGISTRIES

Abstract

In today’s world, where digital technologies play an increasingly important role in various aspects of life, protecting data and ensuring its confidentiality and integrity is becoming an increasingly urgent task. This problem is especially important in the context of state registers, which contain a large volume of valuable information about citizens, businesses and other entities. Delimiting access to public registers is a key task for ensuring security, transparency and efficiency of data management in government bodies. In this context, the use of Non-Fungible Tokens (NFT) and blockchain technology can be a promising solution. This article examines the possibilities of using NFTs and blockchain to delimit access to public registries in Ukraine. This paper defines key concepts such as NFT, blockchain, identification, authentication, and access control and examines their possible applications for delimiting access to public registries. It also describes how the use of blockchain and NFT technologies can be a key solution for ensuring the security and efficiency of public registry management. Blockchain, as a distributed database, provides reliable storage of transaction history and impenetrable encryption of data. Each block in the chain has a unique hash that links it to the previous block, making any attempt to change the data in the blocks nearly impossible without detection. On the other hand, Non-Fungible Tokens (NFT) can serve as unique digital identifiers that define access rights to specific data in public registries. Each NFT contains a unique digital signature that confirms its ownership and characteristics, and can be used to precisely define access rights to specific data or resources. Together, these technologies can create a reliable and secure infrastructure for managing public registries, ensuring transparency, privacy and irreversibility of transactions.
