BLOCKCHAIN: BALANCE OF ANONYMITY AND SECURITY

The purpose of the article is to summarize the problems of the relationship between anonymity and security when using blockchain technologies. The issue addressed in the article is to determine the conditions for the fundamental achievability of sustainable and secure use of the blockchain. Its inconsistency is shown: confidentiality and anonymity create security potential, protecting the user from identity theft and fraud. But the transparency of transactions allows data leakage about the identity of an anonymous user to create threats to the owner of the wallet. The opinions of experts on the possibility of ensuring security while maintaining the anonymity of users are presented, and data on the most common crimes against property associated with the use of blockchain are presented. Blockchain security is also considered in the context of the impact of its use on the environment, and impact statistics are presented. The directions of legal regulation that ensure a balance between anonymity and security are outlined. Results: directions for economic and legal support for the use of blockchain in the areas of sustainable development (in the field of ecology, social interaction, public administration) have been proposed.
