The present article introduces a definition of Blockchain, describes services implemented by this technology and the field of its application. The authors identify the main technical characteristics and their features associated with data transmission through the network. This article provides the operation principles of Blockchain technology and a block structure. The authors determine the network scheme working with blockchain transactions and the dependence of network characteristics on application parameters. The security aspects of data transmission within Blockchain technology are analyzed as well. The types of network attacks and Blockchain devices are listed in the article. In addition, the authors propose a Blockchain traffic identification model that allows discrediting the existing security mechanisms of this technology and makes services vulnerable to these attacks. Furthermore, the article offers recommendations on hiding the Blockchain traffic profile, which will significantly complicate its identification on the data network.
