The article presents a brief analysis of modern «blockchain» technology in terms of information security management and data protection. The general characteristics and features of the «blockchain» technology are presented. Examples of negative properties of this technology, its imperfections and unreliability are given, which causes the deterioration of the criminogenic situation in the modern Internet community. Conclusions about the prospects of this technology are presented. Centralized systems have a number of principal advantages over distributed, built on the basis of «blockchain» technology, from the point of view of ensuring the normal life cycle of the system in the conditions of its constant development and ensuring information security. But they can justify the use of separate elements of «blockchain» technology, which, however, has been done for a long time already.
