Mathematics of Modern Technologies

Modern people cannot imagine their everyday life without a computer, smart phone, and often, a smart TV. We use modern technologies on a daily basis - at work, and during our leisure time. Pressing the phone buttons, we may register for a visit to the doctor's, make purchases, plan our journeys, and look for entertainment.
Currently, a myriad of products and services are based on modern technologies. The world crazy about the crypto currency, i.e. the digital (virtual) currency that lets people avoid banks or other intermediaries and anonymously perform online transactions. This is only one of many examples of modern technologies based on block chain principle.
The opportunities that this technology provides are even greater. It may be and is used in banking and finance sectors, as well as in medical service or elections.
The block chain is officially defined as a decentralized public transactions safety system. The principle of the system may be handled in almost any field of activity that encounter with various types of transactions and record sharing. It is being forecast that the exploitation of the block chain technology will be as much common as the Internet use. Currently, the unaware users are already subject to this technology.
However, the expectation for new directions in Informatics starts with the Discrete Mathematics. The Informatics and Mathematics' bond is especially strong, therefore, there is a growing demand of such specialists, who are able to exploit modern technologies, develop new products for any area of activity, manage and analyze data, take care of its security.
