Research of a Possibility of Using Blockchain Technology without Tokens to Protect Banking Transactions

This paper discusses the use of Blockchain technology without tokens to protect information about banking transactions, namely, transfer amounts, card details, names of participants, etc. This topic is relevant, since the digital economy is becoming an integral part of modern life. The processed information passes through the database of banks and payment systems, which potentially makes it available to the attacker. The article analyzes the protection mechanisms of distributed databases, proposes a solution to the problem of maintaining the uniqueness of information in them based on Blockchain technology without tokens and gives recommendations on the introduction of Blockchain technology into modern banking systems.
