Le criptoattività sfidano i framework contabili, giuridici e fiscali costruiti per gli asset tradizionali. Il libro propone un’architettura interpretativa che intreccia la tecnologia, il diritto e le implicazioni aziendali, dalla Distributed Ledger Technology al Regolamento MiCA, dalla rappresentazione contabile secondo i principi internazionali e nazionali al conseguente regime fiscale. L’analisi procede dalle fondamenta tecnologiche alle questioni operative che i professionisti incontrano nella classificazione degli asset, nelle metodologie di valutazione, nel trattamento tributario e negli obblighi dichiarativi. Il metaverso emerge come frontiera dove blockchain e realtà virtuale generano nuovi paradigmi economici, ponendo interrogativi sulla governance di ecosistemi digitali che sfidano la prassi professionale consolidata.

the article examines the economic efficiency of using domestic artificial Internet technologies in the educational field, which is an urgent problem of state educational policy and management of educational institutions, since the digital transformation of education requires significant investments, the validity of which must be confirmed by economic calculations that take into account both direct effects (cost reduction for the creation and maintenance of physical laboratories, automation interactions between participants in the educational process, reduction of paper document flow), as well as indirect effects (increasing the availability of high-quality education for remote regions, the formation of in-demand competencies in the field of working with distributed digital systems, improving the employability of graduates). Based on the synthesis of the provisions of the economics of education, the theory of network interactions and the analysis of practices for introducing artificial Internet technologies into the educational process, the author examines the main areas of application of domestic solutions in education, including virtual laboratories and simulation environments, platforms for distributed learning based on distributed ledger technologies, systems for conducting online exams with proctoring, as well as tools for automation of interaction between participants in the educational process.

The rapid growth of digital financial services demands secure and privacy-preserving authentication schemes resilient to quantum attacks. The current approaches, which depend on public-key based bilinear pairings, RSA, and Elliptic Curve Cryptography (ECC), are susceptible to quantum algorithms. This paper proposes a novel Distributed Ledger Technology (DLT)-enabled post-quantum authentication scheme that integrates lattice-based cryptography with DLT to ensure quantum resistant, tamper-proof and privacy-preserving transactions. The protocol enables effective multi-phase authentication between users, servers, and DLT nodes by utilising the lattice-based Ring-Learning With Errors (LWE) hard problem for secure key establishment. Security and performance analyses demonstrate low computational overhead, and scalability for real-time financial ecosystems.

The advancement of blockchain technology has revolutionized the field of data security by introducing a decentralized, transparent, and tamper-resistant system originally designed for secure cryptocurrency transaction. Blockchain technology plays a pivotal role in a wide range of data protection applications beyond finance, to sectors like healthcare and supply chain management, where safeguarding sensitive data is essential. This paper explores how blockchain enhances data security by decentralizing data storage, using cryptographic algorithms, and enabling transparency and immutability. Through an analysis of case studies and research literature, we survey the significant impact blockchain has on reducing vulnerabilities, preventing data breaches, and ensuring trust in digital systems. The findings emphasize the potential of blockchain in the revolution of data security while focusing on current limitation in scalability and privacy.

Reentrancy remains one of the most persistent and damaging vulnerabilities in Ethereum smart contracts, enabling adversaries to recursively drain funds despite the presence of static and runtime defenses. Existing studies mainly focus on detection or program analysis, but they do not explain why and under what conditions attackers decide to exploit. In this work, we introduce a decision-theoretic framework that models reentrancy as a profit-maximizing problem under gas, risk, and atomicity constraints. Our framework derives the conditions under which reentrancy attacks are economically viable and provides an algorithm for computing optimal exploit strategies. We further extend the analysis to multi-contract attacks, capturing sequential, parallel, and optimized execution strategies. A simulation environment evaluates profitability across varying balances and gas configurations, highlighting thresholds where attacks become infeasible. Finally, we translate attacker decision profiles into practical defense recommendations for developers, auditors, and DeFi system designers. This framework bridges the gap between exploit detection and adversarial economics, offering a rigorous basis for strengthening smart contract security. This framework establishes a theoretical baseline for adversarial economics in smart contract security, forming a foundation for future MEV-aware exploitability models and Layer-2 risk analysis.

In the context of digitalization of world trade, the task of effective foreign economic administration is becoming more and more urgent. The purpose of the article is to analyze the application of blockchain smart contracts in foreign economic activity. The evolution of the concept, advantages (automation, transparency, savings) and disadvantages, as well as legal limitations, including the lack of international regulation (using the example of BRICS), are considered. The conclusion is made: the introduction of smart contracts optimizes foreign economic activity, but requires a transformation of legislation and the harmonization of international standards.

This is the newest technique to make sure that smart contracts are always secure in very important domains, like world banking. Quantum computers can’t break blockchain rules, hence this is conceivable. The major purpose of this research is to see whether post-quantum cryptography can be combined with blockchain technology to make it safer to move money across borders. Quantum computers might easily get into older blockchain systems since they employ well-known encryption methods like ECC and RSA. This makes it easy for other people to hurt them. As quantum computing becomes more common, the safety of smart contracts used in international banking is becoming more and more at danger. We think that the Lattice-Based Cryptographic Integration Framework (LBCIF) might help with these issues. This system leverages lattice-based post-quantum algorithms like Kyber and Dilithium. These algorithms may keep cryptography safe against quantum assaults. You can use these algorithms to sign smart contracts, prove who you are, and agree on blockchains. The LBCIF is an excellent instrument for trade finance since it uses smart contracts to make settlements and letters of credit with banks all around the world automatic. The framework ensures secure key exchange, digital signature validation, and interoperable transactions across regulatory environments. Findings show that LBCIF maintains performance while significantly improving resistance to quantum threats. It enables secure, scalable, and regulation-compliant smart contract execution for global financial operations.

Progesterone is a vital endogenous steroid hormone extensively used in hormone replacement therapy, contraception, infertility management, and various gynaecological disorders. Despite its significant therapeutic importance, its clinical effectiveness is severely limited by poor aqueous solubility, extensive first-pass hepatic metabolism, and low oral bioavailability. These challenges necessitate the development of advanced drug delivery systems capable of improving its systemic absorption and therapeutic performance. Nanostructured lipid carriers (NLCs) have emerged as a promising second-generation lipid-based nanocarrier system designed to overcome these limitations are composed of a blend of solid and liquid lipids stabilized by surfactants, forming an imperfect lipid matrix that enhances drug loading capacity, stability, and controlled release behavior.
