blockchain

The advent of smart contract technology in blockchain networks has ushered in a new era of possibilities for implementing complex decentralized finance protocols. Over time, these protocols have gained significant traction, reaching a Total Value Locked (TVL) of over 150 billion US dollars. While blockchain networks offer inherent benefits such as immutability, transparency, decentralization, and security, they still grapple with a critical challenge – the inability to ensure a predictable order of transactions within produced blocks.

In an era dominated by concerns of data breaches, and identity theft, security of corporate resources and assets has become paramount. Centralized identity management systems traditionally present vulnerabilities that can fundamentally threaten corporate security. This paper introduces a novel platform to identity management in organizations, leveraging the principles of Self-Sovereign Identity (SSI) and the technological robustness of block- chain.

Many food contamination incidents have occurred during the last decade which has proven the failure of the food supply chain management system to track the food, money, and information movement within the food supply chain.  Many models have been established. This paper presents the design and implementation of the new model providing real-time data acquisition, monitoring, and storing on a tamper-proof blockchain of the main food supply movement.

The article is devoted to the study of new technologies in warehouses; the essence of the “distribution channel” is considered through the analysis of the definitions of this term by various authors; the difference between the supply channel, the goods movement channel and the distribution channel was analyzed; the main changes and problems in the field of distribution over the past few years have been identified; describes the most innovative technologies for digitalization of warehouses.

The decentralized technologies of the Ethereum blockchain were analyzed, based on the principles of which a decentralized software service solution was proposed using a smart contract implemented in the specialized Solidity programming language. This contract acts as one of the elements of the server-client application and is the server part for processing methods of interaction with the Ethereum blockchain. The methods include a set of various functions, including for interacting with a collection of non-fungible tokens.

Discussion issues of the history of Blockchain technology creation and aspects of the international experience of its institutionalization and legal regulation are covered.

The urgency of the researched problem is conditioned by the need to make public administration and public administration in the State more transparent, first of all, through the introduction of such a system of government in which citizens would have confidence. It is noted that society has recently been thinking more and more about e-government, more broadly about ways to create innovative tools that would help better meet government obligations to him. It is emphasized that in this sense, Blockchain is the most promising and truly innovative technology.

The paper considers Blockchain technology and the possibility of its use to prevent software piracy.  There is proposed an approach using Blockchain technology.  An architecture of the License Software Manager has been developed using Blockchain technology.  The software code is available at https://github.com/maksym-demediuk-clicense/clicense.

Abstract. The relevance of the problem mentioned in the title is due to the rapid spread in Ukraine (and not only) of information technologies. It leads to the virtualization of many areas of society, and therefore to the growing importance of storing, transmitting and protecting information electronically, which is processed in global and local information systems using information technologies. Among the latter, according to many scientists (and not only in the IT sphere), Blockchain technology belongs to the leading place (and in the near future this trend will only increase).
