LITERATURE REVIEW The Modern Monetary Theory (MMT), formulated in the early 1990s, (Asada et al., 2023), and the principles of blockchain technology (Kawaguchi, 2019), introduced by Satoshi Nakamoto in 2008, form the theoretical and technological underpinnings of a transformative shift in the global financial paradigm. Together, these frameworks challenge traditional monetary systems and provide innovative solutions through the rise of cryptocurrencies, such as Bitcoin. By offering decentralized, censorship- resistant financial mechanisms, cryptocurrencies transcend the limitations of conventional systems while simultaneously introducing complex challenges related to regulation, monetary sovereignty, and financial stability. Modern Monetary Theory (MMT) MMT posits that sovereign governments (Christopher 1 Department of Finance, University of Carthage, Faculty of Economic Sciences and Management of Nabeul, Tunisia * Corresponding author’s e-mail: boussettajdidi36@gmail.com Pa ge 16 3 https://journals.e-palli.com/home/index.php/ajfti Am. J. Financ. Technol. Innov. 3(1) 162-176, 2025 et al., 2023), as issuers of their own currency, are not constrained by traditional fiscal limits like households or businesses. Instead, their spending is limited primarily by inflationary pressures rather than a need to balance budgets. This perspective shifts the focus from deficit control to effective resource allocation and economic stabilization. In the context of digital finance, MMT raises questions about how decentralized currencies fit into the framework of national monetary policy and economic sovereignty. Blockchain Principles Blockchain technology (Chhina et al., 2024), as outlined by Nakamoto, provides a secure, decentralized ledger that eliminates the need for intermediaries in financial transactions. The foundation of blockchain lies in its: Decentralization Removing central authority by distributing control across a peer-to-peer network. Transparency Ensuring all transactions are publicly recorded on the ledger. Immutability Protecting the integrity of transaction records through cryptographic security. These principles underlie the functionality of cryptocurrencies and form the backbone of their ability to operate independently of traditional financial systems. Cryptocurrencies Ppportunities and challenges Opportunities Decentralization and Financial Inclusion Cryptocurrencies enable access to financial services for underserved populations, especially in regions with limited banking infrastructure. Censorship Resistance By removing reliance on central authorities, cryptocurrencies empower users to transact freely without fear of interference or restriction. Programmable Money Smart contracts, powered by blockchain, allow for automated, conditional transactions that expand the utility of digital currencies beyond simple value transfer. Challenges Regulation and Compliance The decentralized nature of cryptocurrencies poses significant challenges for regulatory authorities. Issues such as money laundering, tax evasion, and market manipulation require novel frameworks that balance innovation with oversight.

Emerging Aspects in Information Warfare: The Economic Front - FinTech and Cryptocurrencies Cryptocurrencies: Unraveling the Dynamics of Digital Financial Instruments In the realm of financial innovation, cryptocurrencies have gone from niche interest to transformative force over the past decade. This digital evolution has ushered in a new era of trading, investment and financial opportunities. Today, cryptocurrency trading is no longer confined to the digital underground, but has entered the mainstream, offering savvy traders ample opportunities to diversify their portfolios. As an expert in the field, I’ll provide an insightful overview of the dynamics within the world of cryptocurrencies. The landscape of cryptocurrency trading is characterized by both incredible opportunity and significant complexity. A defining feature of the crypto space is its notorious volatility, where fortunes can be made or lost in a matter of moments. This volatility was exemplified during the 2022 crypto crisis, when even prominent figures such as Changpeng Zhao, the CEO of Binance1, experienced significant losses of billions of US dollars in a matter of days. Despite the inherent risks, successful crypto investors thrive on these market fluctuations and use them to their advantage by (Allen et al., 2022). In response to the unpredictability of the market, algorithmic trading has emerged as a significant trend. Algorithmic trading uses computer code to automate trades based on pre-defined criteria, capitalizing on high-speed transactions. As the cryptocurrency market operates around the clock, algorithmic trading removes the limitations of human vigilance, increasing accuracy while minimizing the impact of emotion and human error on trading decisions by (Shaik et al., 2023). Another notable development is the rise of decentralized finance (DeFi), which marks a profound shift in the crypto landscape. Rooted in the decentralized ethos of cryptocurrencies, DeFi platforms offer innovative services and products. Yield farming and liquidity mining are prime examples, allowing traders to earn rewards by contributing liquidity to specific protocols, often generating significant returns. In addition, the concept of staking has gained traction, allowing users to passively earn profits by locking up their cryptocurrencies to participate in securing a proof- of-stake blockchain by (Afshan et al., 2024). But along with the remarkable potential for profit, the world of cryptocurrency trading comes with its share of risks. In addition to market volatility, challenges include potential market manipulation, regulatory uncertainty, and technological vulnerabilities. Regulators such as the DOJ, CFTC, and SEC have increased their scrutiny of the digital currency industry, leading to increased regulation in response to market developments. Despite these challenges, the future appears promising for crypto traders, provided the right safeguards are implemented to ensure a safe and well-regulated environment. The dynamics of cryptocurrency trading offer a complex yet enticing landscape for both seasoned and aspiring traders. The intersection of innovation, technology and finance has created a new generation of opportunities and challenges, prompting individuals to navigate the ever-changing currents of the crypto market. To succeed in this space, traders must have a keen understanding of market dynamics, algorithmic strategies, and regulatory developments, while maintaining a calculated approach to risk management. With the right strategies in place, the future holds great potential for crypto traders and the broader ecosystem. Deciphering DeFi: Fundamental Concepts and Core Tenets The profound metamorphosis witnessed in contemporary financial paradigms, embodied by the DeFi revolution, emanates from the central tenet of decentralization. This paradigmatic shift has not only redefined the conventional conceptualizations of financial intermediaries and control but has been the subject of discerning investigations within the scholarly realm (Shah et al., 2023). In elucidating the transformative potential of decentralized systems, Smith and colleagues discern a paradigm wherein decentralization, orchestrated by the intricate mechanics of blockchain technology, engenders a financial infrastructure marked by heightened resilience and imperviousness to tampering. This work. Shah et al. (2023), contends that decentralization serves as a bulwark, obviating the dependence on centralized authorities and fortifying the fabric of financial ecosystems. Furthermore, the erudite inquiries of (Alamsyah et al., 2024) traverse the landscape of decentralized governance models within DeFi platforms. Their discerning findings illuminate the intricate interplay of decentralized decision-making processes, unraveling the nuanced contributions to the robustness and adaptability inherent in financial systems navigating the DeFi frontier. The DeFi landscape is unequivocally propelled by the catalytic force of smart contracts, embodying programmable self- executing contractual mechanisms. Recent scholarship by Siddharth M. Bhambhwani, (Puschmann & Huang- Sui, 2024), accentuates the transformative potential of smart contracts, elevating them beyond mere operational tools to become vanguards of process automation within financial frameworks. Their discerning study unveils the multifaceted impact of smart contracts, delineating how these instruments not only ameliorate operational inefficiencies but also serve as formidable mitigators against the omnipresent risk of human error, thereby fortifying the reliability quotient of financial transactions. Moreover, the scholarly endeavors undertaken by (Bennett et al., 2023), delve into the intricate tapestry of smart contracts, spotlighting their pivotal role in orchestrating complex financial agreements intrinsic to decentralized lending and borrowing. Their incisive Pa ge 16 5 https://journals.e-palli.com/home/index.php/ajfti Am. J. Financ. Technol. Innov. 3(1) 162-176, 2025 findings underscore the efficiency dividends and heightened accessibility ushered in by the deployment of smart contract technology. The foundational bedrock of DeFi platforms resides in the robust edifice of blockchain technology, epitomizing transparency and immutability within financial transactions. Recent scholarly contributions by (Bennett et al., 2023) ,traverse the evolutionary trajectory of blockchain platforms, discerning their instrumental role in shaping the intricate contours of the DeFi ecosystem. Their erudite exploration posits that the utilization of blockchain not only begets secure and transparent financial interactions but also acts as a catalyst in fostering a more inclusive financial milieu. Furthermore, the scholarly opus presented by (Bhambhwani & Huang, 2023), unfurls a meticulous scrutiny of the scalability challenges besieging blockchain-based DeFi platforms. Their discerning insights offer a scholarly compass navigating ongoing efforts to surmount scalability issues, thereby paving an enlightened path for the continued development and pervasive adoption of decentralized financial systems. Figure 1: Architecture of Decentralized Finance Source : binance.com DeFi operates within a stratified framework, delineated in Figure 1. At the foundational stratum, commonly referred to as the settlement layer, the blockchain diligently records and finalizes transactions. Progressing from this foundational layer, developers craft an array of cryptoassets, encompassing indigenous tokens like ETH, stablecoins, and non-fungible tokens (NFTs). Ethereum, as an exemplar, extends its support to an upper tier recognized as the application layer, wherein an array of financial services, including but not limited to lending and asset management, are rendered. Figure 2 delineates a trajectory wherein the aggregate value of cryptoassets ensconced within DeFi contracts experienced a notable surge, subsequently undergoing a retraction coincident with the disruptions witnessed within various cryptoasset trading platforms, such as Terra, Celsius, and FTX, during the course of 2022. Figure 2: Total value Locked in Decentralized finance on Ethereum Source: DeFiLlama; Last Observation: July 2023 Pa ge 16 6 https://journals.e-palli.com/home/index.php/ajfti Am. J. Financ. Technol. Innov. 3(1) 162-176, 2025 DeFi represents a paradigm shift in financial services, emancipating transactions from traditional intermediaries through the utilization of blockchain technology. This is accomplished by employing programmable smart contracts, executable on the blockchain. A concrete illustration of smart contract functionality can be gleaned from collateralized loans, such as mortgages, as expounded upon in the work by (Puschmann & Huang-Sui, 2024). In contrast to conventional lending arrangements reliant on trusted intermediaries, smart contracts assume the role of custodians in the absence of a centralized authority. In a scenario analogous to collateralized loans, a borrower commits a digital asset as collateral within the smart contract, with its release contingent upon successful repayment (Figure 3). Should the borrower default, the smart contract autonomously liquidates the collateral to fulfill the lender’s claim. The deterministic execution of smart contracts, hinging on pre-established conditions, mitigates incentive challenges confronted by traditional intermediaries. DeFi harnesses the potential of these programmable smart contracts to decentralize an array of financial services, as delineated in Table 1. Exemplary instances encompass decentralized stablecoins like Dai, facilitating seamless payments; decentralized exchanges such as Uniswap, fostering frictionless asset trading; lending protocols like Aave; and decentralized asset management platforms exemplified by Yearn. Figure 3: Portrays an illustrative scenario within Decentralized finance Lending Source: www.DeFiLlama.com In this depiction, a borrower engages with a smart contract, committing a digital asset as collateral. Subsequently, the smart contract oversees the lending process, ensuring the secure and automated release of collateral upon successful repayment. In the event of a default, the smart contract autonomously initiates the liquidation of collateral to fulfill the lender’s claim. This visualization encapsulates the decentralized and automated nature of lending transactions within the realm of decentralized. Table 1: Comparative Overview of Financial Services in Cryptocurrency-based Finance vs. Traditional Finance Financial Service Crypto-based Finance Traditional Finance Decentralized Stablecoins Facilitates payments with digital stability (e.g., Dai) Centralized fiat currencies with stable value Decentralized Exchanges Enables frictionless asset trading (e.g., Uniswap) Centralized exchanges with intermediary oversight Lending Protocols Provides decentralized lending services (e.g., Aave) Traditional loans with reliance on trusted intermediaries Decentralized Asset Management Platforms Empowers decentralized asset management (e.g., Yearn) Centralized fund and portfolio management structures Pa ge 16 7 https://journals.e-palli.com/home/index.php/ajfti Am. J. Financ. Technol. Innov. 3(1) 162-176, 2025 This table offers a comparative analysis between financial services provided by cryptocurrency-based finance and those in traditional finance. Cryptocurrency-based finance, exemplified by DeFi, introduces decentralized stablecoins, decentralized exchanges, lending protocols, and decentralized asset management platforms, thereby contrasting with traditional finance, which relies on centralized systems for currency stability, asset trading, lending, and asset management. Figure 4 delineates the market shares of various sectors within the DeFi ecosystem, offering a visual representation of Ethereum’s DeFi system composition. The distribution is based on the aggregate value of cryptoassets secured within the Ethereum DeFi network. Figure 4: Composition of Ethereum’s Decentralized Finance Services Source: http://www.DeFiLlama.com A pivotal characteristic of DeFi lies in its “composability,” a feature driven by the open-source nature of smart contracts. This attribute allows developers to intricately assemble code components akin to Lego bricks, thereby innovating and fabricating novel financial products. A tangible illustration of composability is the synthesis of an exchange contract and a lending contract to formulate a smart contract tailored for margin trading. This inherent ability to seamlessly interconnect different smart contract functionalities not only fuels the expeditious growth of the DeFi ecosystem but also enhances the intricate web of interdependence among its various applications.

Regression Mean Square The regression mean square, calculated by dividing the regression sum of squares by the degrees of freedom, stands at 0.025, indicating the average variability explained by the model for each degree of freedom. F-Statistic The F-statistic, with a substantial value of 434.296, signifies the ratio of explained variability to unexplained variability in the model. This statistic is indicative of the model’s overall significance in elucidating the variance in stock market returns. Significance (Sig.) The significance level associated with the F-statistic is denoted by a p-value of 0.000, implying a statistically significant fit of the regression model. This suggests that the observed relationships between the predictor variables and stock market returns are unlikely to have occurred by random chance alone. The ANOVA analysis underscores the robustness and statistical significance of the regression model in explaining the variability in stock market returns. The substantial F-statistic and small significance value affirm the model’s validity and its ability to capture the dynamics of the stock market with the included predictor variable.

Innov. 3(1) 162-176, 2025 The heatmap reveals significant correlations among the metrics: Stock Market Returns Have a strong inverse correlation with GDP Growth (-0.83), Inflation (-0.84), and the Volatility Index (-0.81). This suggests that higher economic growth and inflation are associated with lower stock returns, while higher volatility corresponds with negative returns. Bitcoin Price Shows a moderate positive correlation with Ethereum (0.59) and the 10-year Treasury Yield (0.65), indicating that crypto movements may align with bond market trends. However, Bitcoin has weak correlations with GDP Growth (-0.32) and Inflation (-0.22), suggesting limited sensitivity to traditional economic indicators. Inflation Rate Has a strong positive correlation with GDP Growth (0.74) and the Volatility Index (0.83), highlighting how rising inflation can spur economic uncertainty and market volatility. 10-year Treasury Yield ,038 ,007 ,188 5,773 ,000*** ,025 ,051 ,439 ,243 ,097 ,265 3,772 GDP Growth Rate -,055 ,005 -,360 -11,507 ,000*** -,064 -,046 -,832 -,446 -,193 ,286 3,495 Inflation Rate -,044 ,004 -,363 -11,279 ,000*** -,052 -,037 -,844 -,439 -,189 ,270 3,709 Volatility Index -,006 ,001 -,233 -6,580 ,000*** -,008 -,004 -,808 -,274 -,110 ,223 4,485 a.

Innov. 3(1) 162-176, 2025 This network graph highlights relationships with a correlation magnitude above 0.5, revealing distinct clusters of interrelated metrics: Cryptocurrency and Bond Cluster Bitcoin, Ethereum, and the 10-year Treasury Yield form a tight cluster, suggesting a strong interrelationship. The correlations indicate that movements in bond yields might influence crypto prices or vice versa, possibly due to shifts in investor risk preferences. Macro-Economic Cluster Inflation Rate, GDP Growth Rate, and the Volatility Index are closely linked, highlighting how inflation and economic growth are significant drivers of market volatility. This cluster suggests that rising inflation tends to accompany higher volatility and economic expansion phases. Stock Market Returns Stock Market Returns are linked to multiple nodes, including Ripple Price, indicating a more dispersed influence across various metrics. The connections suggest that stock returns might react to a mix of macroeconomic factors and specific asset classes, including cryptocurrencies. Conclusion The graph emphasizes two dominant themes: the influence of macroeconomic conditions on market volatility and the interconnectedness of cryptocurrencies and bond yields. Investors should consider these clusters when assessing risk and diversification strategies. • All variables are stationary at the 5% significance level.

Consistency Across Tests Both ADF and KPSS tests consistently confirm that all variables are stationary. This dual confirmation enhances the reliability of subsequent analyses, such as Granger causality and VAR modeling. Implications for Modeling Since all variables are stationary, we can proceed confidently with vector autoregression (VAR) or other time series models without the need for differencing, simplifying the analysis. Caution for Ethereum Price Despite being stationary, Ethereum Price warrants careful monitoring due to its relatively weaker ADF test result, which might suggest sensitivity to external shocks or volatility. Conclusion The stationarity of all variables establishes a robust foundation for predictive modeling, ensuring that parameter estimates and hypothesis tests remain valid and reliable.

J. Financ. Technol. Innov. 3(1) 162-176, 2025 Response to Shocks in PC1 Stock Market Returns (%) → PC1 A positive shock to PC1 triggers a strong and immediate positive response in stock market returns, peaking around period 2. This effect gradually dissipates, indicating that PC1 captures key underlying factors significantly affecting returns. Self-Response (PC1 → PC1) PC1 exhibits a notable degree of persistence, suggesting that shocks to this component have lasting effects. This aligns with the fact that PC1 explains 99.7% of the variance, making it the dominant predictor. Response to Shocks in PC2 Stock Market Returns (%) → PC2 In contrast, shocks to PC2 produce a smaller and more transient impact on stock returns. The effect diminishes rapidly, highlighting PC2’s limited but noticeable predictive power. Self-Response (PC2 → PC2) PC2 shows a quicker stabilization compared to PC1, suggesting that its influence on the market is less persistent. Interactions Between PC1 and PC2 PC1 → PC2 and PC2 → PC1 The IRFs suggest some degree of interaction between the two components, with shocks in one potentially influencing the other. However, the impacts are relatively mild, indicating that PC1 and PC2 capture distinct aspects of market behavior. Stock Market Returns to Itself The IRF for Stock Market Returns (%) → Stock Market Returns (%) shows a cyclical pattern, implying that market returns have some level of autocorrelation or inertia. This characteristic can be critical for forecasting future trends. Conclusion The IRFs confirm that PC1 is the most influential factor for predicting stock returns, while PC2 provides supplementary but limited insights. Dominance of PC1 The strong and persistent response to PC1 shocks reinforces its role as the primary driver of stock market returns. Limited Role of PC2 While PC2 has a detectable influence, its effects are shorter-lived and less substantial. Forecasting Implications The persistence of PC1’s impact suggests that models focusing on this component could significantly improve forecast accuracy.
