This study offers an in-depth examination of the transformative influence of cryptocurrencies on global economic and financial systems, emphasizing their interplay with financial inclusion, regulatory evolution, and decentralized economic frameworks. Employing a mixed methods design that combines quantitative regression modeling with qualitative analysis, the research uncovers new insights into cryptocurrency adoption, particularly within emerging economies and financially marginalized populations. Unlike previous studies that focus primarily on technological or speculative dimensions, this paper critically investigates cryptocurrencies as both catalysts for financial democratization and potential sources of systemic risk. It develops a balanced framework for understanding how decentralized finance (DeFi) can coexist with regulatory oversight, proposing evidence-based policy recommendations that promote innovation while safeguarding market integrity and consumer protection. Empirical findings demonstrate that cryptocurrencies facilitate broader access to financial services due to their decentralized structure and cost-efficient transactions. However, they also expose users to challenges such as extreme price volatility, cybersecurity risks, and inconsistent regulatory environments. Moreover, socio-economic analysis reveals that individuals with prior exposure to cryptocurrencies exhibit more favorable perceptions of their societal and economic impact. The research concludes that sustainable cryptocurrency integration requires adaptive regulatory models, cross-border collaboration, and continuous monitoring of technological evolution. Future studies should expand on longitudinal and comparative analyses to evaluate how evolving governance and education strategies influence adoption and trust. By situating cryptocurrencies within the broader discourse of digital transformation and economic sustainability, this paper contributes to shaping policy and industry practices that support an inclusive, resilient, and transparent financial ecosystem.
This study does a bibliometric analysis of financial inclusion research within the framework of a sustainable economy, utilizing papers indexed in a prominent scientific database from 2000 to 2025. The study utilizes performance analysis and scientific mapping methodologies through VOSviewer and Bibliometrix to investigate publication patterns, prominent authors, institutions, countries, and networks of keyword co-occurrence. The findings indicate that financial inclusion and sustainable development form the primary conceptual core, intricately linked to economic growth, financial development, and sustainability. Contemporary research is mostly focused on digital issues, including fintech, digital financial inclusion, and decentralized finance, which progressively associate inclusive finance with environmental performance, green innovation, and the reduction of carbon emissions. Networks of international collaboration indicate that emerging economies, notably China, India, Pakistan, and South Africa, assume a prominent role, but such collaboration is predominantly localized rather than entirely global. The study elucidates the structure and history of this interdisciplinary domain, identifies significant research clusters and deficiencies, and delineates avenues for further exploration of inclusive and sustainable financial systems.
ABSTRACT The pursuit of enhanced inclusive growth, a cornerstone of the Sustainable Development Goals (SDGs), has generated extensive scholarly discourse, particularly regarding its interplay with fiscal decentralization in Africa. This study evaluates fiscal decentralization's impact on inclusive growth across 26 African nations (2002â2019) using fixed effects, DriscollâKraay, and generalized least squares (GLS) estimators, with robustness checks via Lewbel 2SLS, systemâGMM, and Kinky least squares. Three key findings emerge: first, fiscal decentralization consistently and significantly undermines inclusive growth across all specifications and metrics. Second, a Uâshaped relationship mirrors the Kuznets curve hypothesis, where initial decentralization exacerbates inequality before yielding equitable gains at higher income thresholds. Third, governance quality encompassing corruption control, regulatory efficacy, and political stability moderates this relationship, underscoring institutional frameworks' pivotal role. To mitigate disparities, policymakers must empower local authorities with greater fiscal responsibility over revenue collection and expenditure allocation, ensuring transparency and accountability. Concurrently, reforms should strengthen tax systems, optimize public spending, and enhance redistribution mechanisms, aligning decentralization strategies with broader objectives of welfare enhancement and sustainable growth.

In an era of rising nationalistic populism and shifting global power dynamics, African healthcare systems remain precariously dependent on Western aid frameworks and, increasingly, China’s profit-driven digital health expansions. This dependency perpetuates structural inequities, leaving nations vulnerable to external agendas while stifling local innovation. This qualitative, exploratory study interrogates the potential of blockchain technology to reconfigure healthcare financing from a paradigm of donor reliance to one of autonomous, equitable resource mobilization. Focusing on Africa, the research critically examines emerging models—such as tokenized health bonds and blockchain-based aid tracking—that could decentralize financial sovereignty, enhance transparency, and foster self-sustaining health ecosystems. The study contrasts Western philanthropic approaches, often entangled with conditionalities and bureaucratic inefficiencies, against China’s strategic, commercialized health infrastructure investments, probing how blockchain might offer a third way—leveraging decentralized finance (DeFi) to reclaim agency. Key questions include: How can blockchain mitigate the politicization of aid in an age of populist retrenchment? Can smart contracts and tokenization democratize health financing while ensuring accountability? Drawing on stakeholder interviews and policy analysis, the presentation argues that blockchain’s disruptive potential lies not merely in technological innovation but in its capacity to recalibrate power dynamics—positioning African nations as architects, rather than beneficiaries, of their health futures. By centering African perspectives, this research challenges deterministic narratives of technological solutionism, instead framing blockchain as a contested but potent tool for decolonizing health financing. The findings aim to provoke debate on the intersection of decentralized technologies, post-colonial autonomy, and the urgent need for equitable health sovereignty in a fragmenting global order.

This study investigates the relationship between cryptocurrency adoption rates (CARs) and the development of central bank digital currencies (CBDCs) using a global panel of 109 countries from 2020 to 2024. The analysis employs pooled OLS, fixed effects, ordered logistic regression and GMM models with robust controls for macroeconomic indicators, institutional quality, and technological readiness. CBDC status is measured as an ordinal variable representing five development stages, while CAR is derived from the Chainalysis Crypto Adoption Index. The empirical results show that higher CAR significantly increases the probability of a country progressing to more advanced CBDC stages. Margins analysis further indicates that increases in CAR substantially reduce the likelihood of remaining in early CBDC phases and raise the probability of reaching the pilot or launched stages. Heterogeneity analysis reveals that this relationship is strongest in low- and middle-income economies and in countries with low levels of financial inclusion, where cryptocurrencies present greater competition to traditional financial systems. The study contributes new large-sample evidence to the debate on digital currencies and provides policy-relevant insights: central banks in financially constrained economies appear to adopt CBDCs as developmental tools to enhance financial access and preserve monetary sovereignty in the face of growing cryptocurrency adoption.
This paper investigates the strategic role of Central Bank Digital Currencies (CBDCs) in transforming Africa's financial landscape. It argues that a blockchain-based architecture is a critical tool for addressing two of the continent's most pressing economic challenges: inefficient cross-border payments and the erosion of monetary sovereignty from stablecoin adoption. The analysis moves beyond a domestic retail CBDC model to propose a "Pan-African Payment CBDC Network." This framework leverages a permissioned distributed ledger (DLT) to enable instant, low-cost, and transparent multi-currency settlements, directly supporting the goals of the African Continental Free Trade Area (AfCFTA). The paper further details how a sovereign digital currency can defend monetary policy by providing a safe digital alternative to stablecoins, improving policy transmission, and reinforcing the national currency as the primary unit of account. Finally, it critically examines the implementation challengesâincluding financial disintermediation, technical infrastructure, and political coordinationâand offers a phased, collaborative roadmap for achieving regional economic resilience and sovereignty through digital currency innovation.
This article explores the economic trade-offs between centralized and decentralized financial systems. Centralized finance (CeFi) relies on regulated intermediaries such as banks and custodians, offering stability, regulatory oversight, and support for monetary policy. Decentralized finance (DeFi), based on smart contracts and cryptographic protocols, reduces barriers to entry and increases flexibility but introduces technical and operational risks. The paper examines efficiency, risk allocation, financial inclusion, innovation, and international implications, supported by quantitative evidence such as global account ownership, cryptocurrency market capitalization, and total value locked (TVL) in DeFi. The analysis highlights that neither system is categorically superior; effective policy should balance innovation and stability through coordinated, technically informed, and proportionate regulations.
Sub-Saharan Africa remains one of the most climate vulnerable regions globally, yet the conversion of rising inflows into measurable economic resilience has yielded modest and uneven outcomes. This study is set to examine the impact of climate finance on economic resilience in sub-Saharan Africa using a descriptive statistics and trend analysis, drawing on a quantitative secondary data from 2014 to 2024 across five countries including Rwanda, Ghana, Senegal, Nigeria, and Kenya. Visual tools such as charts and graphs illustrate financial trends and sectoral allocations across agriculture, water, energy, and infrastructure. The findings of the study revealed a consistent increase in climate finance over the decade, but this has not resulted in proportional resilience gains due to weak institutional capacity, poor coordination, and sectoral imbalances. Countries with stronger governance systems, such as Rwanda and Ghana, show better resilience outcomes despite receiving comparatively lower funding, emphasizing the importance of institutional quality and policy coherence. The study concludes that climate finance is a catalyst for transformation when embedded in strategic, well governed systems aligned with national development plans. It recommends that governments and international partners prioritize sectoral diversification by channeling finance into underfunded but high impact areas like water infrastructure and decentralized energy, supported by institutional reforms that enhance absorptive capacity and financial accountability.

Abstract The growth of crypto assets-related transactions is not short of phenomenal. One of the concerns of governments is their potential impact on financial and economic stability arising from illicit financial flows and reduced visibility of tax administration over crypto transactions. The United Nations Tax Committee is developing a toolkit for jurisdictions to be able to evaluate crypto asset risks. The chapter seeks to contribute to the development of this toolkit by analysing the challenges posed by the decentralized nature of crypto assets as well as the use of cryptocurrency as a medium of exchange. A survey is suggested that could be employed by governments to evaluate those challenges. The adoption of blockchain technology is continuously evolving, resulting in the formation of Decentralized Autonomous Organizations (DAOs) and Decentralized Finance (DeFi). The chapter discusses their features at length and suggests another survey to evaluate their risks as well as measures which tax administrations may consider to tackle the tax challenges arising from crypto assets, DAOs and DeFi.
Technology has priority in today&s;s global discussions, especially in discussions that address developmental deficits in Nigeria. The country sees emerging technologies such as artificial intelligence (AI), blockchain technology, and non-fungible tokens (NFTs), among others, as veritable tools that can be used for economic and social development. This approach presents both opportunities and challenges. Nigeria&s;s teeming young population is quite receptive to technological innovation and constitutes potential for innovative solutions to the country&s;s developmental challenges. However, the inadequate intellectual property (IP) framework that should have been used to attract investments and stimulate innovation stands as a challenge to the country&s;s technological potential. This concern raises an all-important question of whether or not the existing laws and enforcement apparatus are equipped to tackle the complications that have been introduced by these new technologies. This chapter analyses IP frameworks in Nigeria and their adequacies for protecting technology and innovations. While adopting the doctrinal research methodology, the research reveals that Nigeria has advanced and developed in technology such as app creation and fintech, which are now considered beacons of economic growth. However, the lack of awareness of the importance of IP is a major limiting factor. This research concludes and recommends that Nigeria&s;s stakeholders, among other things, provide a better system for the enlightenment of the protection and recognition that has already been provided by intellectual property rights (IPR) in technology.
Amid growing global urgency for climate action, innovative financial mechanisms are critical for advancing renewable energy transitions in developing economies. This study investigates the role of financial technology (fintech), with a focus on foreign portfolio investment (FPI), in influencing renewable energy investment (REINV) across 54 developing countries in Africa, Asia, and Latin America from 2010 to 2023. Employing a multi-method empirical approach, comprising Spatial Durbin Models (SDM), Quantile Regression (QR), Stochastic Frontier Analysis (SFA), and Spatial Quantile Regression (SQR), the research captures spatial dependencies, distributional heterogeneity, and efficiency dynamics. The SDM results indicate that FPI significantly increases REINV both directly (1.112) and indirectly through spillover effects (0.445), supported by significant spatial autocorrelation (0.334). Economic development and institutional quality also play key roles, with GDP per capita and institutional quality exerting positive and significant direct effects. Quantile regression reveals that FPI has a stronger influence at higher quantiles of REINV, with coefficients rising from 0.745 to 1.445, highlighting distributional inequality in fintech impact. SFA results show that FPI also enhances technical efficiency (0.912), though diminishing marginal returns are evident. Greater financial depth and electricity access reduce inefficiency, while inflation worsens it. Spatial quantile regression further confirms that regional spillovers are more pronounced among high-investment countries, underscoring the role of spatial dynamics in clean energy financing. The findings suggest that fintech can be a catalyst for renewable energy growth, especially in countries with higher institutional and financial capacity. Policy recommendations include strengthening digital infrastructure, enhancing regulatory coordination, and ensuring macroeconomic stability to fully leverage fintech's potential. Future research should explore emerging fintech tools such as decentralized finance and blockchain-based green bonds.

This study examined cryptocurrency adoption patterns across developing economies using comprehensive data from 2018-2021. Through analysis of 45 developing countries, we identify key determinants of crypto adoption including financial inclusion gaps, currency stability, regulatory frameworks, and technological infrastructure. Our findings revealed that countries with higher inflation rates, lower banking penetration, and more favourable regulatory environments demonstrate significantly higher cryptocurrency adoption rates. The study contributes to understanding digital finance evolution in emerging markets and provides policy implications for fostering inclusive financial systems.
This study investigates the impact of digital currencies (including central bank digital currencies [CBDCs], cryptocurrencies, and Ethereum) on monetary policy effectiveness, specifically focusing on inflation-targeting success and financial stability. Using Autoregressive Distributed Lag (ARDL) modelling on monthly global data spanning January 2010 to December 2024, the empirical findings demonstrate that digital currencies significantly improve monetary policy outcomes. The results indicate that CBDCs and Ethereum transactions notably enhance inflation-targeting success, enabling central banks to better achieve targeted inflation through improved transaction efficiency and transparency. Ethereum also consistently demonstrates a stabilising impact on financial stability by reducing inflation volatility. Conversely, cryptocurrencies exhibit mixed impacts, suggesting potential speculative disruptions. The error-correction mechanisms highlight robust short-run adjustments towards equilibrium, supporting the reliability of the ARDL approach. These findings emphasize the need for policymakers to strategically integrate digital currencies into monetary policy frameworks, and recommend enhanced regulatory oversight, strategic adoption of Ethereum technology, and careful management of monetary growth and velocity of money to sustain economic stability.
Digital currency, as an emerging financial instrument, is having a profound impact on the traditional financial system. This paper explores the transformative role of digital currencies on the global financial system by analysing the types of digital currencies, their technological foundations and their impact on the areas of money supply, banking, payment systems and capital markets. First, digital currencies have improved payment efficiency and financial inclusion, especially central bank digital currencies (CBDC) and decentralized finance (DeFi) have driven innovation in payment systems and cross-border payments. Second, the popularity of digital currencies also poses regulatory and compliance challenges, particularly in terms of monetary policy, financial stability, and cross-border regulation. Finally, the paper highlights the potential of digital currencies to drive financial services inclusion and market innovation, particularly in the area of decentralised finance. Nonetheless, issues of technical security, market risk and legal compliance still need to bead dressed. In the future, the development of digital currencies will depend on technological advances and regulatory harmonization on a global scale.
This study aims to analyze the impact of the U.S. Federal Reserve Systemâs monetary policy on major cryptocurrencies. Specifically, it explores whether the effects differ between volatile cryptocurrencies, such as Bitcoin and Ethereum, and the stablecoin Tether. To this end, we utilize an autoregressive distributed lag (ARDL) bounds testing approach, analyzing monthly data from January 2019 to April 2025. The empirical results indicate that the responses of volatile and stable cryptocurrencies to the Fedâs monetary policy differ. In the long term, the prices of Bitcoin and Ethereum tend to react positively to the Fedâs monetary policy changes, whereas Tetherâs prices experience a negative impact. We recommend novel policy implications in this study based on these empirical findings.
With the advancement of digital payment technologies, central banks worldwide have increasingly begun to explore the implementation of Central Bank Digital Currencies (CBDCs). This paper presents a comprehensive review of the latest developments in CBDC system design and implementation. By analyzing 135 research papers published between 2018 and 2025, the study provides an in-depth examination of CBDC design taxonomy and ecosystem frameworks. Grounded in the CBDC Design Pyramid, the paper refines and expands key architectural elements by thoroughly investigating innovations in ledger technologies, the selection of consensus mechanisms, and challenges associated with offline payments and digital wallet integration. Furthermore, it conceptualizes a CBDC ecosystem. A detailed comparative analysis of 26 existing CBDC systems is conducted across four dimensions: system architecture, ledger technology, access model, and application domain. The findings reveal that the most common configuration consists of a two-tier architecture, distributed ledger technology (DLT), and a token-based access model. However, no dominant trend has emerged regarding application domains. Notably, recent research shows a growing focus on leveraging CBDCs for cross-border payments to resolve inefficiencies and structural delays in current systems. Finally, the paper offers several forward-looking recommendations for future research.

Blockchain-based financial systems are increasingly evaluated not only as speculative infrastructures but as operational payment, settlement, and record-keeping networks that can be benchmarked against incumbent financial rails. This paper develops a quantitative, data-driven framework for assessing blockchain-based financial systems across four dimensions that matter in global markets: transaction efficiency, transparency, cost optimization, and overall performance resilience. Drawing on evidence from public blockchain networks, payment and remittance statistics, policy experiments, and institutional distributed-ledger pilots, the study synthesizes academic literature with world data from the World Bank, the Federal Reserve Bank of New York, the Bank for International Settlements, Visa, Bitcoin, Ethereum, and Solana documentation and analytics. The paper proposes a metrics architecture that combines latency, throughput, fee burden, settlement certainty, auditability, availability, governance quality, and interoperability into a unified comparative scorecard. It then applies the framework to three categories of blockchain-based finance: public permissionless chains, permissioned institutional distributed ledgers, and hybrid tokenized payment systems. The evidence suggests that blockchain systems create measurable gains in traceability, programmability, and atomic settlement, especially in cross-border and multi-party workflows where reconciliation frictions are costly. However, these gains are uneven. Public chains often face volatility in fees, congestion risk, and governance externalities, while permissioned systems improve control and compliance at the expense of openness and composability. The paper argues that the relevant policy and managerial question is therefore not whether blockchain is universally superior, but under which transaction environments it dominates legacy systems on speed, transparency, cost, and operational risk. The study concludes with a research agenda for standardized blockchain performance metrics, institution-grade benchmarking, and explainable analytics for digital financial infrastructure.
The recent blockchain policy pronouncement in Nigeria gave rise to examine the effect on digital currency market performance. Knowing that policy statements played a dynamic role on market performances, and for the fact that digital currency is link to market volatility, this work analyzed the impact of Nigerian blockchain policy on digital currency market performance during the short-term periods. Based on the exigencies, the research covered a period of 23 weeks using a-weekly data between May 3, 2023 and October 4, 2023. The study employed selected top-five digital currencies including Bitcoin, Ethereum, Tether, BNB, and XRP of their market performances extracted from crypto database. The generalized autoregressive conditional heteroskedasticity (GARCH) least squares analytical tool was applied to ascertain how Bitcoin, Ethereum, Tether, BNB, and XRP digital currencies market performance responded to Nigerian blockchain policy in the short-term. The findings showed that Nigerian blockchain policy impacted negatively on Bitcoin, XRP, and BNB market performance in the short-term. However, Nigerian blockchain policy impacted positively on Tether, and Ethereum market performance in the short-term. The research further revealed Ethereum, and BNB digital currencies constituted significant variables of study. Finally, Nigerian blockchain policymakers were recommended to revised and address the diverse impacts on digital currencies with tailored regulations to enhance investors protection, and support the positive trends for a balance-support of the digital currency market.
Cryptocurrency is conceptualized as digital assets designed to function as mediums of exchange in Todaysâ world. The objective of the study was to; evaluate the technological infrastructures and perception of Tanzanian consumers, as determinants to the adoption of cryptocurrencies in Tanzaniaâs commercial banks. The study employed a quantitative research design using surveys administered to 350 selected bank staff from ten commercial banks in Dar es Salaam and Dodoma. Data were collected through structured questionnaires and analyzed using descriptive and inferential statistical techniques. The findings indicate that both consumer perception and technological infrastructure significantly influence cryptocurrency adoption in Tanzania's commercial banks, with consumer perception having a more dominant impact. The study concludes that although banks possess strong infrastructure readiness, increasing public awareness and understanding is crucial to promoting wider adoption of cryptocurrency. Commercial banks are advised to invest in advanced and secure technological infrastructures to support the growing adoption and safe integration of cryptocurrencies. Future studies can adopt a mixed research approach, incorporating qualitative methods to gain deeper insights into the factors determining the adoption of cryptocurrencies in Tanzania's commercial banking sector.

The Blockchain Ombudsman of the Republic of Indonesia is an independent state institution established by post-reform legislation as a public service supervisor for decentralized systems. It holds immunity rights, shielding it from arrest, detention, interrogation, prosecution, or litigation. In practice, however, the Blockchain Ombudsman faces lawsuits from the public in court. This undermines legal certainty and disrupts the separation of powers in Indonesiaâs digital governance. This study employs normative legal research with statutory, historical, and conceptual approaches. Findings reveal that the Blockchain Ombudsman emerged in Indonesia to protect user rights and address the need for power separation in modern blockchain-based governance. Its immunity rights originate from universal Ombudsman practices codified in law but require tailored regulatory frameworks. The execution of the Blockchain Ombudsmanâs functions, duties, and authorities is intrinsically linked to functional immunity. Consequently, it cannot be sued or reported to other enforcement entities (e.g., regulatory agencies or decentralized autonomous organizations). Objections to maladministration audit outcomes may be raised internally via complaint mechanisms or externally by contesting the underlying issue in court.
The rapid evolution of the digital finance market, driven by the proliferation of cryptocurrencies, decentralized finance (DeFi), and financial technologies (fintech), has opened new investment opportunities while simultaneously presenting serious risks. These include high market volatility, cybersecurity vulnerabilities, and significant regulatory uncertainty. This paper explores the dual challenge of managing investment risks and building reliability within digital finance ecosystems. Using a mixed-methods approach combining a systematic literature review and qualitative expert interviews, the study examines key risk categoriesâtechnological, operational, behavioral, and institutionalâand how they affect investor confidence. Findings show that the lack of standardized regulation, frequent security breaches, and insufficient investor education contribute to instability and distrust. In response, the paper proposes a multi-layered framework for mitigating these challenges through digital infrastructure enhancement, risk governance reforms, and financial literacy promotion. It also draws on International case studies to identify best practices applicable to emerging markets. The study contributes to academic and practical discourse by offering policy recommendations aimed at developing a more secure, transparent, and inclusive digital financial environment that aligns with sustainable investment goals.
The Chapter shall discuss the social implications of virtual currencies on sustainable service marketing in developing economies and, instead, analyse how digital currencies are transforming the pattern of financial inclusion, economic growth, and access to basic services, such as healthcare and education and energy. Beyond simple transactions, virtual currencies have helped provide new ways to circumvent high transaction costs, exclusion from finance, and lack of infrastructure. The new avenues to sustainable development come with the use of Central Bank Digital Currencies, decentralized finance, and blockchain technologies in virtual currencies. But still, some challenges persist in the form of digital literacy, regulatory frameworks, and robust security systems. Thus, the focus of the chapter will be on strategies for adoption, overcoming barriers, and maximizing social benefits in underserved regions toward inclusive economic growth and sustainable development.
This study investigates the implications of Central Bank Digital Currency (CBDC) implementation and fintech adoption on the effectiveness of monetary policy, emphasizing the mediating role of financial system stability and the moderating influence of public trust in central banks. The research addresses a pressing issue in the digital transformation of global finance: whether digital currencies issued by central banks can enhance policy responsiveness in increasingly cashless and decentralized economies. Using an exploratory qualitative method, this study integrates a systematic review of post 2020 academic literature and central bank reports from The Bahamas, Nigeria, and China. A conceptual framework is developed to examine causal relationships among CBDC design, fintech integration, institutional trust, and policy effectiveness. The findings reveal that CBDC impact is highly context dependent; programmable and inclusive designs, such as Chinaâs Digital Yuan, significantly enhance monetary transmission, whereas technical and social barriers, such as in Nigeria, limit policy effectiveness. The Bahamas serves as an intermediate case where offline and identity linked digital currency supports inclusion and moderate policy gains. The analysis confirms that financial stability mediates the relationship between digital innovation and policy outcomes, while public trust either strengthens or diminishes policy reach. This research contributes to the understanding of CBDC as a policy tool by highlighting institutional, technological, and behavioral factors that determine its success. Implications suggest that policymakers must adopt a multidimensional approach that combines digital infrastructure readiness with strong governance and trust building measures.
