The adoption of emerging technologies in the finance industry, such as blockchain, promises to provide new perspectives on data security and business processes. This advanced innovation paves the way for unprecedented financial and organizational optimization, transforming not only processes and structures, but also fundamental paradigms of trust and knowledge. The financial industry faces numerous challenges in combating fraud and embezzlement, due to the complexity and scale of its operations. Therefore, the infrastructure provided by the blockchain system helps reduce costs related to intermediaries, enhances security, and improves trust between stakeholders, thanks to the principle of decentralization and the immutability of its ledger. Furthermore, this technological revolution offers financial actors the ability to create new services and solutions in order to meet the needs of several business activities, especially those with complex supply chains. A perfect use of it, will certainly develop the standards of this industry and stimulate innovative economic growth. Although the blockchain offers substantial opportunities for the financial sector, its potential can only be fully achieved with adequate regulatory support, as a way to steer the system toward a more digital and inclusive economy. After a presentation of blockchain technology and its mode of operation, we will be focusing on its potential in finance and how it might provide creative accounting and financial management solutions.

Among all the cryptocurrencies in the market, Bitcoin is the most widely discussed and most popular cryptocurrency in the cryptocurrency market. This study aims to review and summarize the existing literature findings pertaining to the impact of geopolitical risk and economic policy uncertainty on Bitcoin. The results shown geopolitical risk and economic policy uncertainty have predictive power on Bitcoin prices. Both economic policy uncertainty and geopolitical risk have positive and negative effects on Bitcoin. The geopolitical risk and economic policy uncertainty able serve as a hedging instrument against Bitcoin. Bitcoin also can act as a safe haven against geopolitical risk and economic policy uncertainty. A summary of further implication from previous study suggested utilizing other uncertainty measures, applying other cryptocurrency, exploring Bitcoin’s relationship with other financial assets, and employing alternative methodologies.

This study focuses on specifically looking at how penetration testing affects the market value of smart contracts. This study uses a web-based IDE to deploy smart contracts, and it performs penetration testing utilizing reentrancy and delegatecall attacks. The targeted smart contract is exposed to potential exploitation as a result of the assaults' successful implementation. This study shows that penetration testing indirectly affects token prices since incorrect parameter selection and successful attacks might cause changes in token prices. The results emphasize how critical it is to find and fix smart contract vulnerabilities in order to reduce risks and potential losses.

The environmental impact of Bitcoin mining has become a significant concern, prompting several governments to consider or implement bans on cryptocurrency mining. However, these well-intentioned policies may lead to unintended consequences, notably the redirection of mining activities to regions with higher carbon intensities. This study aims to quantify the environmental effectiveness of Bitcoin mining bans by estimating the resultant carbon emissions from displaced mining operations. Our findings indicate that, contrary to policy goals, Bitcoin mining bans in low-emission countries can result in a net increase in global carbon emissions, a form of aggravated carbon leakage. We further explore the policy implications of these results, suggesting that more nuanced approaches may be required to mitigate the environmental impact of cryptocurrency mining effectively. This research contributes to the broader discourse on sustainable cryptocurrency regulation and provides a data-driven foundation for evaluating the true environmental costs of Bitcoin regulatory policies.

The prospects for the widespread introduction of decentralized finance into global financial markets are analyzed. The aim of the study is to consider the opportunities provided to users and investors by the DeFi ecosystem (decentralized finance), and the potential risks of implementing services, applications, protocols based on decentralized financial instruments in both foreign and Russian financial markets. With the help of the theoretical (analysis, synthesis, abstraction) and empirical (comparison, observation) research methods, opinions of leading domestic and foreign experts on the innovative capabilities of DeFi are presented. Based on up-to-date statistical data from the innovative dApps – DappRadar platform, analytical reviews, conference reports, public speeches and expert interviews, initiatives of the main financial regulator of the United States – The United States Securities and Exchange Commission (The United States Securities and Exchange Commission), the Commodity Futures Trading Commission (CFTC), and the Russian Financial Action Task Force (FATF) group for the development of financial measures to combat money laundering, the author emphasizes the need to implement a regulatory framework to settle the spread of decentralized finance. The resulting conclusions are the inclusion of digital assets in the “anti-money laundering” legislation of Russia, as well as a number of other measures aimed at bringing regulatory clarity to the sphere of DeFi initiatives. The main conclusion of the study highlights the difficulties in the large-scale spread of decentralized finance, which is justified by the direct impact of potential risks of using it, distributed by the author to a number of system groups. As a promising predictive model for the development of DeFi, the author proposes a safe harbor model for tokens developed by Hester Peirce. The relevance and scientific novelty of the research are justified by the possibility of using the achieved results (including in the field of analyzing initiatives recommended by large regulatory institutions in relation to uncontrolled financial markets) to introduce a transparent, open, reliable ecosystem of decentralized finance.

Abstract Inadequate oversight and an inchoate appreciation are giving terrorist groups ready access to transboundary financial transfers by means of virtual currency. This chapter counters the prevailing approach that treats cryptocurrency-enabled crimes, such as terrorism, as monolithic. This chapter demonstrates that terrorist groups are using cryptocurrency and decentralized finance to fundraise and transfer funds in conjunction with the traditional financial system. Since actual case studies are few and data limited, this chapter is a proof of concept: it compares terrorist financing schemes by the Al-Qassam Brigades and Al Qaeda that used virtual assets. The comparison of virtual assets being used finds that standards developed and recommended by the Financial Action Task Force (FATF) are wholly inadequate to contain the proliferation of decentralized finance technology and centralized virtual assets as drivers of the global Illicit International Political Economy (IIPE). FATF recommendations are not sufficiently nuanced, nor are they effective at detecting, disrupting and deterring he nexus of crypto, crime and terror. To make matters worse, FATF members are falling short on implementing even FATF’s inadequate standards. The chapter concludes that FATF needs to: clarify inclusion criteria under the current definition of virtual assets; broaden regulations, improve interagency collaboration, and formulate more nuanced recommendations that are sensitive to crypto-enabled crimes across different criminal activities and criminogenic factors.

Smart Contracts (SCs) communicate with each other using external calls. Their interactions can be malicious, resulting in the loss of Ether. One can blame the reentrancy attack for this exploitation. Several previous endeavors detected the reentrancy vulnerability by creating testing tools using static analysis like Remix. However, these approaches do not execute the programs; hence, we cannot confirm their results. In this paper, we present TechyTech that detects both reentrancy and tx.origin vulnerabilities using a novel dynamic analysis approach of involuntary transfer (i.e., unintended transfer). Henceforth, we use a tree-based categorization string to distinguish the two vulnerabilities and their variations. Further, our research discusses multiple SC-related issues like the hijacked stack, deployed owner, and non-generation of transaction receipts in connection with reentrant calls, which we could not find in previous work. Using an example, we demonstrate how the actual Ether transfer is greater than the intended due to reentrancy.We acknowledge that due to dynamic analysis, TechyTech may suffer from VMExceptions.

This article explores the evolution of crypto-anarchy, tracing its origins from the cypherpunk movement to the rise of decentralized finance (DeFi) and its transformative effects on legal and economic systems. Central to crypto-anarchy is the belief in individual empowerment through privacy, financial autonomy, and decentralization, which allows users to bypass traditional intermediaries like banks. While these technologies offer increased freedom and financial inclusion, they also introduce significant risks such as money laundering, tax evasion, and the facilitation of illegal activities, posing challenges to current regulatory frameworks. The article examines the socio-economic implications of decentralization, including both the democratization of finance and the widening wealth disparities, as early adopters often gain disproportionate rewards. Environmental concerns related to energy-intensive cryptocurrencies like Bitcoin and ethical dilemmas surrounding privacy versus accountability are also addressed. The article concludes by examining the potential for AI, blockchain, and decentralized governance models to further disrupt traditional financial and governance structures, while emphasizing the need for robust regulatory frameworks to mitigate risks and ensure long-term sustainability. It envisions a future where decentralized technologies contribute to a more transparent, equitable, and participatory global economy.

This paper presents an ongoing study of a novel attack surface generator tool for smart contracts developed in Solidity. The tool leverages a rule-based engine and ChatGPT API for security analysis. The rule-based engine provides numerical values and key variables and functions for further analysis, while ChatGPT handles complex queries. However, ChatGPT may generate similar responses for more general questions, irrespective of the given contract code. The tool combines both approaches to identify and mitigate potential security vulnerabilities in Solidity-based smart contracts. The effectiveness of the tool is evaluated on real-world smart contracts, and its potential for detecting and preventing common attack vectors is demonstrated.
