Analysis of the Features of Secure Data Processing in Blockchain Technology Based on an Experimental Transaction Exchange Network

mechanisms for secure exchange of transactions are analyzed. The distributed structure of the blockchain network, built on the basis of a sequence of blocks containing transaction data, is considered. The fundamental features of the blockchain technology are described, as well as the 6-component multilayer blockchain architecture. The importance of using cryptographic hash functions to ensure the security and integrity of data in a blockchain network is shown.

Cyber-Physical System of Parking Lot Operation
