Digital assets and the future of finance

Technologies such as cryptocurrencies, non-fungible tokens (NFTs), and decentralized finance (DeFi) systems are reconfiguring markets

Digital assets have been one of the most disruptive and relevant topics on the global stage. Technologies such as cryptocurrencies, non-fungible tokens (NFTs) and decentralized finance systems (DeFi) are challenging economic paradigms, reconfiguring markets, and introducing regulatory and ethical issues. This has caused relevant discussions both in the financial market and in academia regarding this topic.

The existing literature on digital assets reflects the complexity of this phenomenon, addressing topics ranging from widely studied ones, such as volatility and pricing, to emerging issues, such as environmental impact and tokenization of traditional assets. Bibliometric analyses, such as the one conducted by Baskar et al. (2024), which served as the basis for this article, highlight not only the increase in the number of publications but also the evolution of research themes and institutional collaborations, demonstrating the maturity and growing importance of this field.

Since the launch of Bitcoin in 2009, the scientific literature related to digital assets has grown exponentially. The bibliometric analysis conducted in this study shows that the number of academic publications increased from less than 50 per year in 2010 to over 1,500 in 2024. This growth is associated with important milestones, such as the increase in Initial Coin Offerings (ICOs), the popularization of Non-Fungible Tokens (Non-Fungible Tokens, NFTs) and the expansion of Decentralized Finance (Decentralized Finance, DeFi). These events not only boosted academic interest, but also encouraged international collaborations, opening up space for new topics and significant advances in the field.

Baskar et al. (2024) presented a comprehensive review of scientific production on digital assets, using a bibliometric approach to highlight trends, identify the most influential authors and institutions, and map gaps that still need to be filled. Furthermore, they discussed the challenges faced by the sector, such as regulation, accessibility, and security, and pointed out future directions for research and practical applications.

Just as advances in artificial intelligence are modifying various areas, digital assets have the potential to transform the global financial system, offering opportunities and challenges. This article aims not only to explain, but also to inform future practices and strategic decisions in the field of digital assets. To this end, it is essential to understand not only the advances achieved, but also the challenges and gaps that still need to be addressed.

Gaps in the literature

The advancement of research on digital assets has revisited a series of emerging themes that reflect the technological advances and the changes in the economic dynamics, social and environmental. Despite the progress, important gaps still limit a more comprehensive and practical understanding of the impact of these assets.

One of the main challenges is the sustainability and the environmental impact of blockchain technologies, especially those based on Proof-of-Work (PoW), like Bitcoin. PoW uses a competitive mechanism in which miners employ large amounts of computational power to solve complex mathematical problems, ensuring transaction validation and network security. This process is highly energy-intensive, resulting in high environmental costs. On the other hand, Proof-of-Stake (PoS) selects validators based on the amount of cryptocurrency they hold and are willing to “stake” as collateral, eliminating the need for energy competition and drastically reducing energy consumption. For example, according to recent data, Bitcoin consumes approximately 204.5 TWh of energy per year, equivalent to Thailand’s energy consumption, while Ethereum, which migrated to the PoS mechanism, reduced its energy consumption by over 99%, illustrating the potential of less energy-intensive solutions (Ali et al., 2024; Lin, 2023).

Another important research focus is the regulation of digital assets. The accelerated development of these technologies often surpasses the regulatory capacity of governments, creating uncertainties for investors and hindering large-scale adoption. The collapse of the exchange FTX in 2022, due to unregulated practices, is a clear example of the risks of this regulatory gap, causing losses to thousands of investors. Issues regarding global harmonization remain particularly relevant in emerging economies. In countries like El Salvador, for example, the adoption of Bitcoin as legal tender has brought financial inclusion, but has also exposed significant risks due to the asset’s volatility and the absence of a robust regulatory infrastructure.

The adoption of digital assets in emerging economies is another area of focus. In regions with limited banking infrastructure, cryptocurrencies have been used as a store of value and a medium of payment, offering viable alternatives for financial inclusion. In Kenya, for example, platforms like BitPesa enable low-cost international transfers, benefiting small businesses and workers who rely on financial remittances. However, digital exclusion in rural areas still represents a significant obstacle. Similarly, in India, stablecoins have been used to offer secure and accessible payment alternatives in rural areas. Despite these initiatives, broader analyses of the social and economic impacts of this adoption remain scarce.

Furthermore, the security of blockchain networks is a critical topic. Despite advancements, attacks on smart contracts, fraud in exchanges, and other vulnerabilities continue to pose significant risks, especially for individual investors. The attack on Poly Network in 2021, which resulted in the theft of over US$600 million, highlighted the need for more rigorous code audits and more resilient networks. In parallel, exchanges like Binance have been implementing monitoring tools based on artificial intelligence to mitigate fraud, but small investors remain vulnerable to schemes such as phishing and rug pulls.

Finally, the limited interdisciplinarity within the field is a significant barrier. Most studies focus on economic or technological perspectives, neglecting integrations with areas such as law, ethics, and social sciences. The Venezuelan context offers an illustrative example. Faced with economic difficulties and the depreciation of the bolívar, marginalized communities in Venezuela have turned to cryptocurrencies, especially stablecoins like USDT, to preserve value and conduct transactions. However, significant challenges persist, such as digital exclusion in rural areas and the lack of digital literacy, which limit the broader adoption of these technologies (Mattos et al., 2020).

Additionally, studies such as “El nuevo dólar gris en Venezuela es digital” highlight how the growing dependence on digital assets in this context evidences the need for analyses that transcend purely economic dimensions. These challenges are amplified by cultural and infrastructural barriers, which hinder equitable access to technological innovations. Without an interdisciplinary approach, which considers social and cultural factors, cryptocurrencies run the risk of perpetuating existing inequalities, rather than mitigating them (El País, 2024).

Therefore, future analyses should explore the interactions between technology, society, and economy, promoting a more comprehensive understanding of the impact of digital assets in vulnerable contexts. This includes integrating areas such as social sciences and law, seeking solutions that address both the benefits and risks associated with the adoption of emerging financial technologies.

The identification of these emerging themes and gaps presents a unique opportunity for interdisciplinary collaborations that accelerate the development of innovative solutions. Future research should prioritize regulatory frameworks that balance innovation and safety, the development of sustainable technologies, and the exploration of how digital assets can promote social inclusion and economic inclusion. By addressing these issues, it will be possible to maximize the positive impact of digital assets and transform them into fundamental tools for sustainable global development.

Future

Digital assets are redefining the global financial system, promoting innovation, inclusion, and efficiency. From the emergence of Bitcoin to the popularization of NFTs and DeFi, these technologies have expanded the boundaries of finance and introduced new regulatory, environmental, and technological challenges. Despite this, advances in the field, such as tokenization, and the use of sustainable technologies highlight their transformative potential.

Challenges, such as high volatility, environmental impact, and lack of uniform regulation, still limit its large-scale adoption. Overcoming these barriers will require cross-sector collaboration, balanced regulatory frameworks, and investment in technologies that combine sustainability and security. Furthermore, integration with traditional financial systems and the promotion of digital inclusion are essential to expand its scalability and social impact.

With collaborative and innovative approaches, digital assets have the potential to build a more resilient and accessible financial system, transforming the global economy for future generations.

Determinants of supermarket location in São Paulo

A study investigated the determining factors for supermarket location in the state of São Paulo, with the objective of investigating the factors that explain the presence and expansion of these establishments, considering socioeconomic, demographic, and market dimensions. Data from the 2010 and 2022 Demographic Censuses of IBGE and information from the National Registry of Legal Entities of the Federal Revenue of Brazil were used to build a georeferenced database. A Random Forest classification model was applied, adjusted by grid search with cross-validation, prioritizing the recall-macro metric due to the imbalance of the dependent variable, which represented the presence or absence of supermarkets within a 50-meter buffer. The results indicated that supermarket location is strongly associated with demographic, income, and population characteristics in the surrounding area. The analysis of variable importance showed that sociodemographic factors, such as elderly literacy, household income, and the presence of other food establishments, exerted significant influence, especially in the immediate vicinity. The findings reinforced the hypothesis that the spatial distribution of supermarkets is not random, being conditioned by socioeconomic characteristics and the commercial structure of the territory, offering subsidies for business decisions and urban planning.

Anti-Racist Education: Inclusive Educational Practices and Social Development

Antiracist education, understood as a structuring axis of inclusive education and social development, was investigated in the Brazilian context. The study aimed to identify and analyze, based on legal documents and teachers’ perceptions, educational practices capable of promoting antiracism in school and society, and how the implementation of Laws nº 10.639/03 and nº 11.645/08 contributed to social justice. A qualitative and documentary approach was adopted, with analysis of educational legislation, curricular guidelines, institutional reports, and academic literature. Complementarily, a semi-structured questionnaire was applied to 295 Basic Education teachers. The data were evaluated quantitatively and qualitatively, through thematic content analysis, and validated with bibliographic studies. The results revealed a paradox: despite a robust legal framework, the implementation of antiracist policies proved fragile and sporadic, with a lack of teacher training, adequate teaching materials, and monitoring. Significant educational inequalities between white and black students were found to persist, and most teachers acknowledged the occurrence of racism in schools, but without clear institutional protocols. Neuroscientific analysis showed that racism negatively impacts students’ cognitive and emotional development. It was concluded that antiracist education is central to quality education, requiring political commitment, public investment, and intersectoral articulation. The integration of Neuroscience in teacher training and the production of qualified materials are crucial to strengthen the school’s role in building a more just and inclusive society.

Data Transformation into Strategy: Applied Research for Ecotourism Operation Optimization

The growing demand in ecotourism in Minas Gerais has driven the search for business intelligence to transform customer data into strategic information. The study aimed to structure a data science pipeline to collect, segment, and classify the customer base of an ecotourism operation, in order to optimize marketing actions and anticipate market movements. An exploratory, quali-quantitative research was conducted through a case study. 2,777 transactional records from an ecotourism company, referring to January 2024 to December 2025, were used. The methodological process involved automated data collection (Google Sheets API), processing and enrichment (ETL), validation, and creation of RFM (Recency, Frequency, and Monetary Value) attributes. Dimensionality reduction via PCA and K-Means clustering was applied, with the number of clusters defined by the Elbow method and Silhouette Score. The results were validated with DBSCAN and K-Medoids. The results revealed the identification of three behavioral customer segments: “Loyal”, “Low Value”, and “Potential”. The “Loyal” segment represented the highest accumulated economic value, while the “Potential” segment stood out for its high average ticket and potential for conversion into recurrence. The integration of data analysis techniques proved to be a robust and replicable method for generating intelligence in ecotourism. It was concluded that the structured data science pipeline enabled the behavioral segmentation of the customer base, the statistical validation of the groups, and the creation of a predictive system for new buyers, providing subsidies for data-driven strategic decisions and future analyses.

Classification of defaulting customers using supervised machine learning techniques

The risk of default in credit operations demanded analytical approaches to anticipate losses. This study comparatively evaluated the performance of supervised machine learning models in classifying defaulting customers in credit card operations. The public dataset “Default of Credit Card Clients” from the University of California Irvine was used, with 30,000 observations and class imbalance. The algorithms Logistic Regression, Random Forest, and Extreme Gradient Boosting were employed. The imbalance was addressed by assigning weights to the classes, and model optimization occurred with the RandomizedSearchCV method, prioritizing sensitivity. Cross-validation results indicated that the Extreme Gradient Boosting model showed a higher capacity for identifying the defaulting class and better discriminatory performance, followed by Random Forest and Logistic Regression, with a sensitivity of 0.8250 and an AUC-ROC of 0.7844 for XGBoost. Interpretability analysis, conducted by the Shapley Additive Explanations (SHAP) technique, highlighted the predominance of variables associated with payment behavior, especially the history of delays. It was concluded that tree-based models, particularly boosting techniques, proved to be more suitable for capturing complex patterns in the data, configuring themselves as consistent alternatives for credit risk management.

Optimization of annual budget planning through project management methodologies

The Annual Budget Planning (POA) is a crucial process for translating organizational strategy into operational and financial goals, but it frequently faces deadline pressures, interdepartmental dependencies, and the repetition of habitual expenses. The study aimed to analyze how the combined application of project management practices and Zero-Based Budgeting (OBZ) can optimize the POA. To this end, a case study was developed in the Brazilian operation of a publicly traded company in the beverage sector, using documentary research of its 2023 results report and an anonymous questionnaire applied to 47 respondents. Documentary analysis indicated growth in net revenue, expansion of gross profit and adjusted EBITDA, and contained advancement of selling, general, and administrative expenses, suggesting cost discipline and operational leverage. The complementary survey revealed a high perception of cascading effect on the schedule, strong support for defining cost package owners, and a preference for technical justification of expenses, in addition to demand for controlled flexibility after the baseline definition. It was concluded that structuring the POA as a project, associated with the rigor of OBZ, increased the process predictability, reinforced accountability for expenses, and broadened the coherence between budgetary execution and economic-financial performance.
