Abstract
Due to the emergence of advanced technologies and a variety of applications, Blockchain technology is now becoming an important element on modern communication networks due to its technical capabilities and features. The article considers the behavioral model of Blockchain services, and its reliability is confirmed on the basis of experimental data. The authors consider the definition of Blockchain, advantages and disadvantages of this technology. In this article, the authors consider the main network attacks that networks with Blockchain nodes are subjected to. The authors identify the main technical characteristics and their features related to the transmission of information through the network, determine the network scheme when working with Blockchain transactions, and the dependence of network characteristics on application parameters. The analysis of the use of this model for detecting Blockchain services and the possibility of discrediting the existing security mechanisms of this technology is carried out. The article describes the key results of the experiment in which traffic analysis was performed. The authors presented graphs of the intensity of data exchange at different stages of the Blockchain technology. Also in this article, the authors give the dependence of the distribution of the number of packages on their size and the dependence of the density of the distribution of time intervals between packages. The presented experiment showed that the dependence of the distribution of the number of packets on their size and the dependence of the density of the distribution of time intervals between packets are close to the lognormal law. In addition, the article provides recommendations for hiding The blockchain traffic profile, which will significantly complicate its identification on the data transmission network.
Keywords: Blockchain, distributed registry, security, data protection, network, decentralized systems.
