Smart contracts enable autonomous execution between contracting parties without a centralized authority, thereby reducing contract management costs and enhancing the transparency and reliability of contracts. However, the absence of such a certification authority increases the risk of fraud. Rug-pull, a typical form of fraud, involves developers hiding backdoor codes in smart contracts to steal funds under certain conditions, causing significant damage to users. A Rug-pull list warns users of potential fraud, but it only identifies risks after damage has occurred. Additionally, existing backdoor code analysis tools are limited in their ability to detect backdoor codes hidden through modifications to existing patterns or suffer from low accuracy because they rely on comparisons with predefined backdoor codes. Therefore, this paper proposes a balance-tracking-based backdoor code detection model to identify backdoor codes in smart contracts. The proposed model detects backdoor codes by extracting functions from Ethereum bytecodes and inspecting the extracted functions to track balance changes. This approach allows for the detection of balance changes even when backdoor codes are concealed. Experimental results verifying the effectiveness of this model demonstrate 98% accuracy, 0.96 recall, and 0.98 precision. These results are expected to contribute significantly to effectively reducing fraud risks such as Rug-pull.

The field of cryptocurrencies is in existence and dynamically evolving for over 14 years. Each year introduces new cryptocurrencies, with their total number exceeding 8,500. However, to date, there is no exhaustive categorization of cryptocurrencies that could possibly fully describe the landscape of the cryptocurrency market, which underscores the relevance of this research. The objective of this study is to construct a hierarchical categorization (taxonomy) of cryptocurrencies based on their main characteristics and functions. The principal research method is a retrospective analysis of the development of the cryptocurrency field from the creation of Bitcoin to the present day. As the industry evolved, new projects emerged, which significantly differed in their properties from what existed before, thus forming entirely new categories and niches in the cryptocurrency space. Moreover, the emergence of certain types of cryptocurrencies could lead to changes in the existing classification. The outcome of this research is a taxonomy of interchangeable cryptocurrencies/tokens. The proposed taxonomy is accompanied by a detailed examination of the cryptocurrencies associated with each category, as well as a consideration of the largest cryptocurrencies in terms of capitalization through its prism. The scientific novelty of this research lies in the absence of similar studies that look at the issue of categorizing cryptocurrencies through a historical lens.

Blockchain technology, characterized by features such as decentralization, is transforming the financial system and providing new tools for financial crime governance. However, its characteristics like anonymity are also exploited by criminals, giving rise to new types of financial crime. This paper analyzes its "double-edged sword" effect from a financial professional perspective: first, it outlines the technical principles and current applications; then, it explores its empowering mechanisms as a "sharp sword" in anti-money laundering, combating terrorist financing, and enhancing transaction transparency. Subsequently, it analyzes its abuse as a "dark blade" in criminal activities such as cryptocurrency money laundering. Employing the financial regulation "trilemma" framework, the paper argues for the necessity and challenges of seeking a balance between decentralization, privacy protection, and effective regulation. It proposes comprehensive governance pathways, including building an adaptive regulatory framework that synergizes "RegTech" and "Compliance Tech." The research indicates that guiding blockchain technology to serve financial security and stability requires acknowledging and mastering its dual nature.

This bachelor thesis focuses on the role of cryptocurrencies in the process of laundering the proceeds of crime, particularly in the context of money laundering. The aim of the thesis is to explore how cryptocurrencies, due to their anonymity and decentralized nature, facilitate the process of money laundering and circumvention of financial regulation, thus providing new opportunities for criminals to carry out illegal transactions. The theoretical part of the thesis focuses on the theoretical underpinnings of cryptocurrencies and blockchain technology that are key to their operation, and explores in detail the money laundering process and its phases. The thesis analyzes the mechanisms by which cryptocurrencies are used to mask the origin of illicit financial flows and their subsequent legalization. The practical part of the thesis includes simulations of cryptocurrency transactions using real tools to anonymise financial flows that criminals can use to launder illicit funds. At the end of the work, the weaknesses of the cryptocurrency sector regulations are identified and possible measures are proposed to reduce the risk of its abuse in illegal activities.

Stablecoins have become a critical element of the cryptocurrency ecosystem, offering benefits such as value stability, efficient cross-border transactions, and enhanced access to Decentralized Finance (DeFi) and everyday payment systems.Their increasing adoption demonstrates their capacity to transform financial processes by enabling faster transactions, reducing fees through blockchain technology, and expanding financial inclusion for unbanked populations.However, these advantages come with significant national security concerns, including the risks of illicit financial activities, gaps in regulatory oversight, and potential disruptions to monetary policy.This article explores the implications of stablecoins for Nigeria's national security, focusing on their usage, regulatory challenges, and associated risks.It highlights vulnerabilities such as the potential for market manipulation, exploitation by criminal networks, and the use of stablecoins for money laundering, cyberattacks, and other illicit financial activities.The article also examines how these risks could undermine financial stability and national security, particularly in a context of limited regulatory capacity.By drawing lessons from global regulatory frameworks, the study stresses the urgent need for Nigeria to develop robust regulatory measures to address these risks and ensure financial stability.It calls for a balanced approach that promotes innovation while safeguarding the integrity of the financial system.

In the era of deep integration between the digital economy and globalization, virtual currencies represented by Bitcoin, with their decentralized architecture, anonymous transaction characteristics, and crossborder circulation advantages, have become a new carrier for cross-border money laundering crimes. Statistics show that the global virtual currency money laundering scale exceeded the $20 billion threshold in 2024, with cross-border money laundering accounting for 60%. The cross-regional mobility, technological concealment, and regulatory arbitrage characteristics of such crimes pose a subversive challenge to the traditional anti-money laundering governance system. Through in-depth deconstruction of the four core models of virtual currency money laundering—anonymous wallet mixing services, cross-chain bridging and decentralized finance (DeFi) operations, and darknet trading ecosystems—it is evident that they face governance dilemmas in electronic data forensics, such as massive and decentralized data storage and enhanced anonymity technology countermeasures. In response to the new patterns of money laundering crimes in the big data era, public security and judicial authorities need to break down industry barriers, establish cross-departmental judicial collaboration mechanisms, and promote the construction of cloud-based think tank systems. These measures will significantly improve the efficiency and accuracy of electronic data forensics, providing a solid judicial guarantee and technical support for combating cross-border virtual currency money laundering crimes and safeguarding national financial security and order.

<b>RESUMO:</b> A última década testemunhou a consolidação das Finanças Descentralizadas (DeFi) e a busca por maior eficiência nos mercados de capitais através da tokenização de Ativos do Mundo Real (RWA). Este artigo propõe o Unified Structured Finance Protocol (USFP), uma arquitetura DeFi híbrida projetada para a tokenização e negociação de produtos estruturados (como Debêntures, ETFs e COEs) no contexto regulatório brasileiro. O problema de pesquisa central é: Como desenvolver um <i>framework</i> de protocolo DeFi que preserve a eficiência e a liquidez da descentralização, ao mesmo tempo em que acomoda os requisitos rigorosos de <i>Anti-Money Laundering</i> (AML), <i>Know Your Customer</i> (KYC), e relatórios regulatórios exigidos para a tokenização de valores mobiliários no Brasil? Os objetivos são: 1) Propor o <i>Unified Structured DeFi Note</i> como um meta-ativo tokenizado. 2) Detalhar uma arquitetura de protocolo que integra um Módulo de Compliance (<i>RegTech</i>) e um AMM Regulado (RL-AMM). 3) Analisar o encaixe conceitual dessa arquitetura no panorama regulatório brasileiro (CVM/BACEN). A contribuição principal (Tese) é que a viabilidade de protocolos DeFi para o mercado de capitais brasileiro reside na separação funcional entre a liquidação descentralizada (<i>trustless</i>) e o acesso permissionado (<i>trusted</i>) [8]. Esta abordagem define um novo modelo de Infraestrutura de Mercado de Capitais Programável (<i>D-CMI – Decentralized Capital Market Infrastructure</i>), essencial para a tokenização de RWA regulamentados. A centralização intencional dos pontos de controle de acesso (KYC/AML) e de relatórios permite que o regulador mantenha a supervisão, enquanto as operações de <i>payoff</i> e negociação se beneficiam da eficiência <i>on-chain</i>
