Blockchain technologies can be used in any industry where verification and logging of certain actions are required. In particular, in the manufacture of medicines it is necessary to have reliable information about the origin of the raw material from which the drug is made, and the process of production of the drug. Blockchain provides protection against counterfeiting and counterfeit drugs. The article describes the model of the contract system blockchain and the work of miners in the chain "manufacturer-pharmacy". According to this scheme, blockchain technology can be implemented in the production and supply of medicines. The proposed model allows us to trace the origin of pharmaceutical raw materials and medicinal products, to guarantee the quality of drugs entering the pharmacy warehouse and pharmacy. This will protect the market from counterfeit medicines.

The problem of preserving the cultural heritage and promoting it into dynamic modernization development is associated with the historical and cultural memory in the processes of identification of the individual and society. This is especially true for regions that do not have developed industry or agriculture, and are positioned mainly as tourist-recreational or resort areas. These zones include the region of Caucasian Mineral Waters. For its development, it is important not only to preserve the existing historical and cultural layer, but also to ensure its popularization and promotion, attracting new tourists and holidaymakers to the Kavminvody. Modern information technologies make it possible to do this using the resources of the global Internet. The article considers the issue of creating a specialized Internet resource that will collect, store and popularize information about the cultural and historical objects of the Caucasian Mineral Waters. This is a database that will be presented on the Internet as a website. On the site you can find both popular articles about the history and features of the selected object, as well as more complete and specialized information collected by historians, local historians, architects, artists, restorers. The data that is planned to be presented on the site can be useful both to specialists working on the conservation and use of the cultural and historical sites of the Caucasian Mineral Waters, and to tourists who can use the Internet resource to create routes for walking and trips to interesting but undeservedly forgotten tourist sites Caucasian Mineral Waters region.

One of the important possible directions of blockchain technology implementation is the sphere of housing and communal services. The use of blockchain in accounting for the received utilities and payment for them can make these processes absolutely transparent, understandable and verifiable, which is not always done with the current system of payment for housing and communal services. The paper describes the algorithms of interaction between suppliers and consumers of housing and communal services on the basis of blockchain technology, hashchain and cryptography methods. Blockchain procedures for concluding a contract for the supply of utilities, accounting for consumption, billing, payment for services and resolving problems have been developed. The proposed methods allow both providers and consumers of ESIA to guarantee the accuracy and reliability of the data, as well as their protection and indestructibility.
