Challenges of Law Enforcement in Combating Cryptocurrency Based Money Laundering In Indonesia

Gregorius Widiartana

The rapid development of cryptocurrency as a digital financial asset has introduced new challenges for the prevention and eradication of money laundering crimes. While cryptocurrencies offer efficiency, decentralization, and borderless transactions, these very characteristics also create significant vulnerabilities for misuse, particularly in facilitating illicit financial flows. In Indonesia, the existing legal framework on anti-money laundering, primarily regulated under Law Number 8 of 2010, was formulated prior to the widespread adoption of cryptocurrency and therefore faces limitations in addressing technology-driven financial crimes. This article examines the challenges of law enforcement in combating cryptocurrency-based money laundering in Indonesia through a normative juridical approach. The study analyzes relevant statutory regulations, institutional authority, and enforcement mechanisms involving agencies such as PPATK, Bappebti, the Financial Services Authority, and law enforcement bodies. The findings indicate that law enforcement faces substantial obstacles, including regulatory fragmentation, jurisdictional complexities, difficulties in tracing blockchain-based transactions, evidentiary constraints, and limited technical capacity among enforcement institutions. Furthermore, the absence of comprehensive regulation concerning decentralized finance and non-custodial digital wallets exacerbates enforcement difficulties. This article argues that without regulatory harmonization, enhanced institutional coordination, and the integration of technological capabilities into law enforcement practices, the Indonesian legal system risks lagging behind the evolving landscape of financial crime. Strengthening adaptive legal frameworks is therefore essential to ensure effective anti-money laundering enforcement in the digital asset era.

StableAML: Machine Learning for Behavioral Wallet Detection in Stablecoin Anti-Money Laundering on Ethereum

Luciano Juvinski, Han Li, Alessio Brini

Global illicit fund flows exceed an estimated $3.1 trillion annually, with stablecoins emerging as a preferred laundering medium due to their liquidity. While decentralized protocols increasingly adopt zero-knowledge proofs to obfuscate transaction graphs, centralized stablecoins remain critical transparent choke points for compliance. Leveraging this persistent visibility, this study analyzes an Ethereum dataset to establish an empirical baseline for behavioral AML detection. Our findings demonstrate that domain-informed tree ensemble models achieve higher Macro-F1 score, significantly outperforming graph neural networks, which struggle with the increasing fragmentation of transaction networks. The model's interpretability goes beyond binary detection, successfully dissecting distinct typologies: it differentiates the complex, high-velocity dispersion of cybercrime syndicates from the constrained, static footprints left by sanctioned entities. This methodological approach provides actionable insights that align with industry shifts toward deterministic verification, informing the auditability and compliance requirements under regulations such as the EU's MiCA and the U.S. GENIUS Act while minimizing unjustified asset freezes. By providing a high-precision behavioral classification of suspicious wallets, this approach contributes to raising the economic cost of financial misconduct while informing compliance practice under emerging stablecoin regulations.

Cryptocurrency Regulation in India: Legal Uncertainty, Financial Stability, and Digital Sovereignty

Pooja Kumari

The rapid global expansion of decentralized cryptoassets has confronted state authorities with complex regulatory, fiscal, and structural challenges.[1] In India, this tension is uniquely pronounced. The state has chosen to navigate private digital innovations by asserting its authority across multiple domains: maintaining structural barriers, implementing rigorous taxation frameworks, and advancing state-controlled alternatives. This research paper evaluates the three-dimensional matrix shaping India's cryptocurrency policy ecosystem: macro-legal uncertainty, systemic risks to financial stability, and the pursuit of digital sovereignty.By analyzing judicial shifts—such as the landmark Internet and Mobile Association of India (IAMAI) v. Reserve Bank of India case—alongside contemporary anti-money laundering amendments under the Prevention of Money Laundering Act (PMLA), the strict fiscal regimes established via the Finance Acts, and the parallel rollout of the Digital Rupee (e₹) as a Central Bank Digital Currency (CBDC), this paper demonstrates how India has constructed a de facto containment strategy. It concludes that while this approach has successfully mitigated systemic exposure and curbed capital flight, the persistent lack of an integrated statutory framework leaves retail investors exposed, keeps the domestic web3 ecosystem in legal limbo, and highlights the ongoing friction between private cryptographic protocols and sovereign monetary controls.

Γρηγόριος Ράπος

Η παρούσα διδακτορική διατριβή διερευνά τον εξελισσόμενο ρόλο του Bitcoin στο διεθνές χρηματοοικονομικό σύστημα, εστιάζοντας τόσο στις δυναμικές αλληλεπιδράσεις του με τις παραδοσιακές αγορές, όσο και στους μακροοικονομικούς παράγοντες που καθορίζουν τη μεταβλητότητά του. Η διατριβή αποτελείται από τρία εμπειρικά δοκίμια. Στο πρώτο κεφάλαιο εφαρμόζεται η μεθοδολογία των Atasoy και Özkan (2024), η οποία επιτρέπει τον εντοπισμό περιόδων εντός του συνολικού δείγματος κατά τις οποίες εκδηλώνονται επεισόδια contagion μεταξύ των εξεταζόμενων μεταβλητών. Το προτεινόμενο πλαίσιο συνδυάζει το υπόδειγμα DCC-GARCH με χρονικά μεταβαλλόμενους ελέγχους αιτιότητας κατά Granger, προκειμένου να διερευνηθεί η ύπαρξη contagion μεταξύ του Bitcoin και βασικών κατηγοριών περιουσιακών στοιχείων, όπως οι μετοχές, ο χρυσός, τα ομόλογα και ο δείκτης δολαρίου των ΗΠΑ. Τα αποτελέσματα καταδεικνύουν ότι παρατηρείται σποραδικό και μη συστηματικό contagion, γεγονός που υποδηλώνει ότι το Bitcoin δεν συνιστά πηγή συστημικού κινδύνου. Ωστόσο, η περίοδος της πανδημίας COVID-19 αποτελεί σημείο καμπής στη δομή των συσχετίσεων, καθώς οι δυναμικές συσχετίσεις εμφανίζουν διαφοροποιημένα πρότυπα και εντονότερες διακυμάνσεις, ιδίως όσον αφορά τη σχέση του Bitcoin με την αγορά μετοχών των ΗΠΑ. Το δεύτερο κεφάλαιο επεκτείνει την ανάλυση του πρώτου, προβαίνοντας σε σαφή διάκριση μεταξύ contagion και interdependence. Η ανάλυση πραγματοποιείται στο πεδίο των συχνοτήτων, αξιοποιώντας τη μεθοδολογική προσέγγιση των Bodart και Candelon (2009). Τα αποτελέσματα αναδεικνύουν την ύπαρξη αμφίδρομου contagion αλλά και interdependence μεταξύ του Bitcoin και μεγάλων διεθνών χρηματιστηριακών αγορών, ιδίως των Ηνωμένων Πολιτειών, κυρίως κατά την μεταπανδημική περίοδο. Τα αποτελέσματα αυτά υποδηλώνουν αυξανόμενη ενσωμάτωση στις διεθνείς χρηματοπιστωτικές αγορές του Bitcoin τόσο με ανεπτυγμένες όσο και με αναδυόμενες οικονομίες και αμφισβητούν την υπόθεση του «ασφαλούς καταφυγίου», υποστηρίζοντας ότι συμπεριφέρεται κυρίως ως περιουσιακό στοιχείο κινδύνου. Στο τρίτο κεφάλαιο διερευνώνται οι μακροοικονομικοί προσδιοριστικοί παράγοντες της μεταβλητότητας του Bitcoin μέσω ενός μικτής συχνότητας υποδείγματος GJR-GARCH-MIDAS-X, το οποίο ενσωματώνει 21 μακροοικονομικούς δείκτες. Τα αποτελέσματα δείχνουν ότι δείκτες οικονομικής και χρηματοοικονομικής αβεβαιότητας, η βιομηχανική παραγωγή, οι χρηματοοικονομικές συνθήκες, η ρευστότητα και μεταβλητές που σχετίζονται με τον πληθωρισμό επηρεάζουν σημαντικά τη μακροχρόνια μεταβλητότητα του Bitcoin. Συνολικά, τα ευρήματα της διατριβής υποδεικνύουν ότι το Bitcoin έχει μετεξελιχθεί από ένα σχετικά απομονωμένο ψηφιακό περιουσιακό στοιχείο σε ένα ολοένα και περισσότερο ενταγμένο στο διεθνές χρηματοπιστωτικό σύστημα και εξαρτώμενο από μακροοικονομικές συνθήκες χρηματοοικονομικό μέσο, χωρίς ωστόσο να συνιστά έως σήμερα πηγή συστημικού κινδύνου για το παγκόσμιο χρηματοπιστωτικό σύστημα.

Cryptocurrency Flows in Illegal Market

Abhinav B. Date, Amit Karbhari Mogal

Abstract This research investigates how cryptocurrencies are used in illegal markets, including darknet marketplaces, ransomware payments, and money laundering. The study examines transaction patterns, anonymity techniques, and the tools used by cybercriminals to hide illicit flows. To understand the increasing complexity of these activities, the research explores how digital currencies enable fast, borderless, and pseudonymous transactions that often bypass traditional financial regulations and monitoring systems. The study combines blockchain analysis, case studies, and expert observations to map these illegal flows and identify system vulnerabilities. By assessing the role of mixing services, privacy-oriented cryptocurrencies, decentralized exchanges, and chain-hopping techniques, the research highlights the methods used to obscure the origin and destination of digital assets. These insights help reveal how criminals exploit technology to move funds in ways that challenge traditional policing mechanisms. The findings aim to provide valuable insights for policymakers, cryptocurrency exchanges, and law enforcement agencies to improve detection, prevention, and regulation of illicit cryptocurrency activities. The research also examines current regulatory frameworks, global compliance standards, and existing technological tools used to trace illegal transactions. Furthermore, it discusses the challenges faced by authorities, including cross-border jurisdiction issues, lack of unified regulations, and the rapid advancement of blockchain technologies. Overall, this study contributes to a deeper understanding of how illegal cryptocurrency markets operate and highlights opportunities for strengthening cybercrime prevention through improved regulations, data-sharing frameworks, and innovative blockchain forensic solutions.

The Dark Web of Cryptocurrency: Unpacking the Nexus between Digital Currencies, Cybercrime, and Global Governance

AbdulMalik Olalekan Oladipupo

This study explores the intersection of cryptocurrency, cybercrime, and global governance. It focuses on identifying criminal techniques, analyzing forensic and regulatory countermeasures, and evaluating the broader governance dilemmas that arise. A qualitative desk-based approach was employed, synthesizing secondary data from peer-reviewed studies, institutional policy papers (FATF, IMF, Europol), and industry reports (Chainalysis, Elliptic, TRM Labs). Thematic content analysis was used to trace patterns in illicit cryptocurrency use, law enforcement responses, and regulatory innovations. The findings indicate that while advances in blockchain forensics and policy coordination have strengthened oversight, criminals increasingly exploit decentralized finance platforms, cross-chain laundering, privacy coins, and mixers to evade detection. Enforcement remains uneven, hindered by fragmented regulations and gaps in cross-border cooperation. Overall, the study concludes that cryptocurrency-enabled cybercrime remains a resilient and evolving threat that challenges the stability of the global financial system and exposes weaknesses in governance frameworks. Without stronger coordination, adaptive regulation, and robust technological capabilities, the risks of illicit finance will continue to outpace control efforts. To mitigate these risks, the study recommends enhancing cross-border collaboration, investing in advanced blockchain forensic tools, and adopting flexible, multi-stakeholder governance models that balance innovation with accountability.

Digital Ownership or Digital Deception? Understanding Fraudulent Behaviour in NFT Markets through the Fraud Triangle Lens

Rajsee Joshi Shah, Cerin Elsa Joji

Abstract: The non-fungible token (NFT) marketplace has rapidly evolved into a transformative space, experiencing remarkable growth in recent years. NFTs serve as digital ownership certificates linked to unique assets such as art, collectibles, and digital media, exemplifying blockchain innovation. This paper employs an exploratory, systematic literature review of Scopus-indexed sources to examine the fraud-prone dimensions of the NFT ecosystem. Using the fraud triangle framework—pressure, opportunity, and rationalization—it investigates individual and organizational drivers of deceit. The study identifies major fraud types including rug pulls, wash trading, Ponzi schemes, whitelisting, and phishing, offering insights to guide policymakers and participants in mitigating NFT-related risks. Keywords: Non-Fungible Tokens, Blockchain, Digital Fraud Vulnerabilities, Three-Factor Fraud Framework, Risk Mitigation JEL Classification Number: G32, G18, K83, K24, O33

Blockchain Forensics for Cryptocurrency-Driven Cybercrime

Seema Verma, Padmesh Tripathi, Pridhi Arora

Blockchain and cryptocurrencies have transformed the way digital transactions work by introducing decentralisation, transparency, and immutability. However, these features also allow some individuals to use them for cybercrimes. This chapter explains how blockchain records can be used to trace, investigate and mitigate such crimes. It also talks about how understanding the behaviour of users can help in finding out who the attackers are. This chapter begins with the basic ideas of blockchain and cryptocurrency, after this, it describes different types of cybercrimes that usually happen using cryptocurrency and also explains that traditional ways of investigating cybercrimes don't work well with blockchain and new frameworks are required to investigate and solve these cases. A key section of the chapter examines how blockchain forensics helps in detecting cybercrimes. User-centric threat intelligence will be explored to understand the people behind cybercrimes that can help in investigations. In the chapter, Legal and ethical considerations will be addressed.

Blockchain Forensics and Regulatory Technology for Crypto Tax Compliance: A State-of-the-Art Review and Emerging Directions in the South African Context

Pardon Takalani Ramazhamba, Hein Venter

The rise in Blockchain-based digital assets has transformed the financial ecosystems, which has also created complex governance and taxation challenges. The pseudonymous and cross-border nature of crypto transactions undermines traditional tax enforcement, leaving regulators such as the South African Revenue Service (SARS) reliant on voluntary disclosures with limited verification mechanisms, while existing Blockchain forensic tools and regulatory technologies (RegTechs) have advanced in anti-money laundering and institutional compliance, their integration into issues related to taxpayer compliance and locally adapted solutions remains underdeveloped. Therefore, this study conducts a state-of-the-art review of Blockchain forensics, RegTech innovations, and crypto tax frameworks to identify gaps in the crypto tax compliance space. Then, this study builds on these insights and proposes a conceptual model that integrates digital forensics, cost basis automation aligned with SARS rules, wallet interaction mapping, and non-fungible tokens (NFTs) as verifiable audit anchors. The contributions of this study are threefold: theoretically, which reconceptualise the adoption of Blockchain forensics as a proactive compliance mechanism; practically, it conceptualises a locally adapted proof-of-concept for diverse transaction types, including DeFi and NFTs; and lastly, innovatively, which introduces NFTs to enhance auditability, trust, and transparency in digital tax compliance.

Blockchain Technology as Trust Infrastructure for Third-Party Risk Management

Sagar Behere

Contemporary organizational ecosystems are critically vulnerable in third-party risk management frameworks due to centralized databases, fragmented documentation systems, and manual processes of assessment. Traditional approaches result in huge inefficiencies through redundant audits, version control complexities, and delayed responses for compliance along multi-jurisdictional vendor networks. The blockchain architecture introduces a fundamental architectural transformation through distributed ledger mechanisms, creating immutable audit trails, cryptographic verification protocols, and decentralized trust formation across organizations. The article reviews how blockchain works as an integrity infrastructure within regulatory technology ecosystems, allowing the automation of compliance through smart contracts, making transparent records available for authorized stakeholders, and removing single-point vulnerabilities from centralized control systems. The technical mechanisms for implementation include immutable vendor record systems, which integrate fragmented documentation into unified, tamper-proof ledgers; smart contract automation that allows deterministic outcomes in governance; and distributed assurance networks, which allow audit verification among multiple organizations. Regulatory dimensions are related to preserving privacy through hybrid on-chain and off-chain architectures, legal recognition challenges of smart contracts within jurisdictional frameworks, and ethics in governance requirements for human input within automated ecosystems of decisions. Implementation challenges involve the complexity of legacy system integration, the development of a structure for consortium governance, scalability constraints, and the scarcity of talent. Future trajectories include hybrid ecosystems, integrating blockchain's immutability with advanced analytics, tokenized reputation frameworks, and integrations with emerging technologies such as artificial intelligence and digital identity systems toward next-generation vendor risk governance.

Protecting Investors from Meme Coin Scams: A Smart Analysis Tool

Naman Naman, Shivani Chourey, Surya Gupta

Meme coins have become extremely popular in the cryptocurrency market, but they also carry a high level of risk. Many of these projects rely on social media hype and community excitement, yet a large number eventually turn out to be scams where developers steal investor funds and abandon the project, commonly known as rug pulls. This paper presents a smart analysis tool designed to help investors identify such risky meme coin projects before financial loss occurs. The proposed system examines both smart contract behavior and market-related factors, including ownership control, liquidity locking, token distribution, and developer wallet activity. The tool was tested on real-world meme coins, including well-known legitimate projects as well as confirmed scam tokens. The results show that the system is able to accurately distinguish between safe and high-risk projects. This approach provides a practical and effective way to improve investor safety in the rapidly evolving decentralized finance ecosystem

Bitcoin Custody Failure Modes: A Taxonomy for Professional Interpretation

CustodyStress

Bitcoin custody systems are designed by individuals with full contextual knowledge and later encountered by others—executors, trustees, attorneys, heirs—who must interpret and operate these systems without the original owner present. This interpretive gap produces recurring failure patterns that persist even when custody components technically exist. This paper presents a taxonomy of failure modes observed in Bitcoin custody systems when those systems are encountered under stress conditions including death, incapacity, device loss, and institutional failure. The taxonomy distinguishes between legal authority and cryptographic access, between security and survivability, and between documentation that enables action and documentation that merely describes existence. Seven failure mode categories are examined: (1) documentation without usability, where correct and comprehensive records nonetheless fail to enable execution; (2) time as an active dependency, where dormant systems degrade through institutional change, memory loss, and technological obsolescence; (3) dependency overlap, where apparently redundant components share hidden common roots; (4) partial access traps, where incomplete recovery attempts constrain or block subsequent paths; (5) authority-access misalignment, where legal entitlement and operational capability diverge; (6) coordination failure, where distributed control prevents action when parties cannot align; and (7) delay-induced state changes, where outcomes differ based on when recovery is attempted. The paper provides canonical vocabulary for professional communication about custody situations and offers a scenario reference for modeling system behavior under stress. It is intended as a descriptive reference for fiduciaries, estate planning attorneys, and advisors who encounter Bitcoin custody systems in professional contexts. The paper does not provide recommendations, evaluate custody arrangements, or establish standards of care.

GAS4SEC: Toward a Secure and Optimized Smart Contract for Digital Chain of Custody in Digital Forensics

Baysah Guwor, Rijwan Khan, Mohammad Shabaz

It is evident that blockchain offers strong guarantees of integrity and transparency for handling digital evidence; however, its practical adoption has remained a challenge due to factors such as privacy, deployment constraints, and admissibility issues in the real word environment. This study, therefore, proposes GAS4SEC, a framework for designing, validating, and deploying a secure, cost effective, and forensically sound blockchain-based evidence management system. The system combines formally bound smart contract architecture with role-based access control, record of immutable evidences and custody processes to maintain authenticity, traceability and accountability. In order to overcome the security risks and challenges, the research includes the systematic vulnerability analysis correlated with the OWASP smart contract risks to make sure that unauthorized access, logic abuse, and invalid state transitions are addressed. A validation-based process of development imposes forensic invariants and security guarantees across the lifetime of a contract, and controlled gas optimization is used to achieve better deployment without affecting the evidentiary integrity. The proposed system is deployed and tested on the Polygon Layer-2 blockchain, with functional testing, security testing, gas testing, and stress testing with evidence operations and role change concurrency. The experiment proves that the approach can be used to achieve scalable and cost-effective on-chain forensics operations without sacrificing the high levels of security assistance and forensic integrity and proves to be applicable to the management of digital evidence in practice.

The Digital Offshore: What Jeffrey Epstein Likely Saw in Bitcoin

David Krause

This article explores Jeffrey Epstein's financial habits, focusing on his longstanding efforts to evade traditional banking oversight and his early interest in emerging financial technologies such as Bitcoin. While there is no evidence linking cryptocurrency to his criminal activity, newly released records and reporting reveal that Epstein studied and invested in technology, seeking ways to minimize reliance on regulated intermediaries. The piece argues that Epstein's attraction to Bitcoin's features, especially its capacity to bypass formal banking structures, parallels the reasons cryptocurrency later became popular in illicit financial networks.

The Party's Over: How the Bitcoin ETF Killed Crypto's Cool Factor

David Krause

This paper documents a structural break in the risk return characteristics and cultural relevance of cryptocurrencies following the approval of the first spot Bitcoin ETF on January 10, 2024. Using daily price data from January 2021 to June 2026, we compare pre ETF and post ETF performance metrics, betas, and event study cumulative abnormal returns for Bitcoin, Dogecoin, and Ethereum relative to the S&P 500 and gold. We then introduce two independent measures of public interest, Google Trends and Wikipedia page views, to test the hypothesis that Bitcoin lost its cultural "coolness" after institutionalization. The findings are striking. Dogecoin, the quintessential speculative asset, saw its Sharpe ratio collapse from 0.30 pre ETF to 0.01 post ETF, while its annualized return fell from 63.17% to 2.82%. Google search interest for Dogecoin declined 63.1% and its Wikipedia page views collapsed 75.9%. Searches for "how to buy Bitcoin," a proxy for new retail entrants, declined 22.7%. In contrast, general "cryptocurrency" interest fell 47.5%, while Bitcoin maintained a stable Sharpe ratio and saw its beta relative to the S&P 500 decline from 1.33 to 1.11. An event study reveals that the Trump 2024 election produced a +47.37% cumulative abnormal return for Dogecoin, but this proved temporary. The MSTR sale in May 2026, Michael Saylor's first Bitcoin sale since 2022, generated a-6.56% abnormal return for Bitcoin. These results support the thesis that ETF approval marked a cultural as well as financial regime shift, as retail speculative energy exited the crypto market and Bitcoin moved toward more of a diversifier role.

Economic Criminology in the Digital Era: Algorithmic Detection of Money Laundering and Tax Evasion in Blockchain Networks

Robson Monteiro dos Santos

The rapid expansion of blockchain-based financial systems has fundamentally transformed the structure of economic crime. While distributed ledger technologies provide unprecedented transparency, they simultaneously enable pseudonymous interactions that can be exploited for illicit financial activities, including money laundering and tax evasion. This paper develops a theoretical and computational framework for detecting illicit financial behavior in blockchain networks. By integrating economic criminology, graph-based analysis, and machine learning techniques, it proposes a composite detection model capable of identifying suspicious transaction patterns through structural and behavioral indicators. The study argues that blockchain-based financial crime is not hidden but structurally embedded within transparent systems, requiring algorithmic interpretation rather than traditional investigative approaches. The findings highlight the importance of scalable, data-driven enforcement mechanisms and coordinated regulatory responses in addressing financial crime in decentralized environments.

Effect of Quality Regulatory Framework on Prevalence of Cryptocurrency-Related Financial Crimes in Nigeria

Abdul-rahman AHMAD, Mohammed Bashir Abdullahi, Yahaya YUSUF

The paper examined the effect of quality regulatory framework on perceived prevalence of cryptocurrency-related financial crimes in Nigeria. Employing mixed methods approach with survey data from 385 respondents and thematic analysis of 15 regulatory documents and 8 expert interviews, the study utilized descriptive and Ordinary Least Square (OLS) regression analysis. Diagnostic tests confirmed no serious multicollinearity (VIF < 5), heteroscedasticity (Breusch Pagan p > 0.05), and normality of residuals (Jarque Bera p > 0.05). The results revealed a significant relationship from improved monitoring tools (RUMT, β = 0.0939, p < 0.01) and blockchain compliance mechanisms (BCAC, β = 0.0960, p < 0.01) to the perceived prevalence of financial crimes thereby indicating rise in financial crimes and by exposing previously hidden irregularities. In addition, regulatory guidelines exhibit a weak deterrent effect (RAGC, β = -0.0412, p < 0.10), attributable to weak enforcement by agencies responsible for implementation (e.g., EFCC, NPF), lack of clarity in guidelines issued by the CBN and SEC, and fragmented institutional structures on AML/CFT (despite CBN and SEC being the guideline issuers, enforcement lags due to poor coordination among regulators and law enforcement). Customer Due Diligence Verification (CDDV) was statistically insignificant, indicating that traditional KYC/AML mechanisms are insufficient against sophisticated crypto-related activities involving mixers, decentralized finance platforms, and offshore exchanges. However, Culture of Compliance (CCUL, β = 0.0531, p < 0.05) and geopolitical zone (β = -0.0341, p < 0.05) also significantly shape perceptions. The findings suggest that Nigeria remains in an awareness stage of regulation defined as a phase where detection and monitoring capabilities improve (evidenced by positive coefficients for RUMT and BCAC) but enforcement mechanisms lag behind, allowing crimes to be identified more readily without commensurate reduction. Law enforcement agencies such as EFCC and NPF should prioritize strengthening enforcement capacity and adopting advanced blockchain analytics as the first step; policymakers (National Assembly, CBN, SEC) should ensure regulatory frameworks are clear and comprehensive, thereby reducing ambiguity and institutional fragmentation among CBN, CAC, NFIU, and others.

A Secure Blockchain Framework for Smart Property Ownership Verification Using Smart Contracts

Viraj Kiran Kulkarni, Manisha Kshirsagar

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.

Canadian Financial Infrastructure Exploited in Transnational Fraud

Emela Enyinna

This report examines the convergence of generative artificial intelligence, cryptocurrency laundering infrastructure, and cross-border social engineering in the evolution of romance scam-enabled financial crime affecting Canadian institutions. Drawing on reporting from the Federal Bureau of Investigation Internet Crime Complaint Center (FBI IC3), the Financial Transactions and Reports Analysis Centre of Canada (FINTRAC), the Royal Canadian Mounted Police (RCMP), and blockchain analytics firms Chainalysis and TRM Labs, the analysis identifies a measurable transition from opportunistic, manually-operated fraud schemes toward industrialized transnational operations. The report documents how AI-generated personas, deepfake impersonation tools, and multilingual automation systems have reduced operational costs for fraud actors while increasing victim acquisition at scale. Particular attention is given to cryptocurrency laundering pathways — including stablecoin conversion, decentralized finance (DeFi) layering, cross-chain transfers, and over-the-counter (OTC) broker off-ramping — that exploit the opacity of digital asset ecosystems and exceed the detection capabilities of traditional threshold-based anti-money laundering (AML) monitoring systems. The report further assesses Canada's specific vulnerability profile, attributing heightened exposure to widespread Interac e-Transfer adoption, high public trust in digital financial systems, and fragmented cross-border compliance coordination. Three systemic risk vectors are identified and analyzed: the industrialization of victim acquisition, increased laundering opacity through decentralized cryptocurrency infrastructure, and the systematic exploitation of Canadian digital payment rails. Recommendations are directed at the Economic and Financial Crimes Commission (EFCC), Nigerian financial intelligence agencies, and Canadian financial institutions and cryptocurrency platforms.
