The rapid growth in the volume of personal data collected and processed by various organizations poses significant challenges for ensuring information privacy and security. The General Data Protection Regulation (GDPR) of the European Union sets strict requirements for the processing, storage, and deletion of personal data, including the right to be forgotten, which entails the complete and irreversible deletion of information upon user request.

mechanisms for secure exchange of transactions are analyzed. The distributed structure of the blockchain network, built on the basis of a sequence of blocks containing transaction data, is considered. The fundamental features of the blockchain technology are described, as well as the 6-component multilayer blockchain architecture. The importance of using cryptographic hash functions to ensure the security and integrity of data in a blockchain network is shown.

The article investigates the process of block formation in blockchain networks and the impact of node network architecture and consensus algorithms on their scalability and performance. Analysis of blockchain system scalability is important due to problems that arise when network load increases, particularly the increase in the number of block forks and transaction confirmation times. The research focuses on studying the impact of network delays and the choice of consensus algorithm on the performance and scalability of blockchain networks.

The rapid growth of the Internet of Things (IoT) has revolutionized the logistics industry by enabling real-time tracking and monitoring of goods throughout the supply chain. However, the immense volume of telemetric data generated by IoT devices presents significant challenges in terms of scalability, data integrity, and security for traditional database solutions. This paper explores the applicability of blockchain technology as an alternative for storing and managing IoT telemetric data in logistics.

Purpose of the research. Exploration of the research gaps in order to understand how DAOs can encourage initiatives/practices to protect the interests of various stakeholders as well as identifying and comparing the main problems and prospects for creating and scaling DAOs in the existing economic realities. The following hypotheses that DAO is a form of science-oriented entrepreneurship and creates opportunities for involving unused entities in diverse   economic processes were analyzed.

The article explores the application of blockchain technology in the field of arms sales accounting. The authors examine the main methods of forming such technology, including distributed ledger, hash functions, cryptographic protection, smart contracts, consensus protocols, decentralized network, transactions, genesis block, decentralized governance, and public key. The authors analyze the potential of these methods in creating an efficient and secure arms sales accounting system.

Abstract. The article is devoted to a comprehensive study of technologies designed to protect intellectual property rights. The scientific basis for the study of information technologies for ensuring the protection of intellectual property rights is analyzed.

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.
