The Use of Blockchain Technologies to Ensure the Information Security of Distributed Systems

The article discusses the problem of storing confidential information in private blockchain platforms using the examples of Hyperledger Fabric and Confidential. A comparative analysis of these platforms is carried out and a new algorithm for storing confidential data in private and public registries is proposed. The new algorithm for storing confidential information involves the use of “smart contracts” technology to automate data processing and storage processes. This allows you to automatically check user access rights and control the transfer of information between network participants.
