The use of blockchain technology can provide complete decentralization of domain names and distribution of content across a larger number of nodes, which will make it virtually invulnerable to cyber attacks The article identifies the technological aspects of the introduction of Blockchain technology, substantiates the main characteristics of this technology, and notes the accepted typology of Blockchain varieties depending on the specifics of implementation and technological features. There are varieties of algorithms for "consensus" agreements, both in the context of technologies.
