У статті описано та досліджено різницю між децентралізованою та централізованою інформаційними системами. Вивчено ефективність використання та впровадження у виробництво нових технологій. Проаналізовано побудову систем на базі блокчейну та їх ефективність у вирішенні поставлених завдань. Сформовані висновки про тенденції, що впровадження децентралізації доводять потребу в цифрових системах управління в той час, коли реалізація технології блокчейн значно спростила побудову нових децентралізованих систем, що є актуальною тенденцією в світі.
Ключові слова: система управління, оптимізація, об’єктно-орієнтоване програмування, блокчейн.

This article describes and investigates the difference between a decentralized and a centralized information system. The efficiency of use and introduction of new technologies in production is studied. The construction of blockchain-based systems and their efficiency in solving the tasks are analyzed. Conclusions are formed about the tendency that the introduction of decentralization proves the need for digital management systems. At a time when the implementation of blockchain technology has greatly simplified the construction of new decentralized systems, which is a current trend in the world. The basis of blockchain technology is in a distributed information storage. It allows you to store important information simultaneously on many servers, and therefore keep them open and safe. For example, on the basis of this technology it is possible store both the history of customers’ bank transactions, voting results, and database of contracts, fingerprints or medical histories. And the information that stored simultaneously in many places, it is impossible to steal it, because in any case they can be restored from the original sources. As already mentioned, a blockchain, a block of transactions, is a structure for writing transaction groups. Transactions are carried out only when it is considered confirmed. It is reliable and convenient when it comes to making payments or the transfer of confidential data. So that the transaction is considered confirmed, its format and signatures must be verified. After that, the group transactions are recorded in a special block. In these blocks, all data is fast to verify. And in each subsequent information about the previous is stored. For example, in transactions on cryptocurrencies, the chain contains blocks information about all actions ever performed with bitcoins. The block includes a header and a list of transactions. The title of the block has its own hash, previous block hash, transaction hash and other additional official information. The first thing that is specified in the transaction block is getting a commission that will be as a reward, so the user who actually and will create this block. For transactions in the block tree hashing was used.
Keywords: programming paradigm, object, function, object-oriented programming, functional programming, blockchain.
