The present study analyzed the utilization of the CDF for climate resilience projects in vulnerable communities of Sinazongwe District, Southern Province. It was observed that vulnerable communities in Sinazongwe continue to experience water scarcity, reduced agricultural output, and livelihood insecurity, despite the availability of expanded CDF resources meant to address these climate stresses. The study adopted a descriptive case study design with a mixed-methods approach, and sampled 120 respondents using both random and non-random (purposive or non-probability) sampling procedures. The study then employed the semi-structured questionnaires to community members/beneficiaries, to gather quantitative data; as well as the conduction of interviews using the semi-structured interview guide on the CDF committee members, WDCs, and government officials, to gather in-depth qualitative insights; and FGD held with community groups to understand collective perceptions, and challenges. The findings revealed that major CDF-funded climate resilience interventions included borehole drilling and rehabilitation, irrigation projects, conservation farming, tree planting, and water supply systems. Water-related projects were identified as the most significant interventions because they improved access to water, household food security, irrigation activities, and community coping capacity during drought periods. The study further established that community participation mainly occurred through community meetings and Ward Development Committees, although participation remained largely consultative rather than fully empowering. The findings also revealed that political influence, inadequate funding, delayed disbursement of funds, limited technical expertise, weak monitoring systems, and poor integration of DRR affected effectiveness and sustainability of climate resilience interventions. The study concluded that CDF has significant potential to support local climate resilience and livelihood improvement through decentralized financing. However, climate resilience interventions remained inadequate relative to increasing climate-related risks affecting vulnerable communities in Sinazongwe District. The study recommends increased climate-focused funding under CDF, stronger integration of Disaster Risk Reduction into local development planning, improved community participation, strengthened governance and accountability systems, enhanced technical capacity, and greater investment in early warning systems, environmental conservation, and sustainable livelihood diversification.
Purpose This study develops a pricing and contract design framework for cryptocurrency catastrophe (CAT) bonds to transfer extreme crypto-native risks, including protocol exploits, exchange breaches and decentralized finance (DeFi) failures, to capital markets. The paper aims to address arbitrage-free valuation, sponsor-optimal contract design and trustless settlement under the unique informational and operational features of blockchain systems. Design/methodology/approach We propose a multi-trigger crypto CAT bond structure that jointly captures short-term catastrophic shocks and long-term systemic deterioration through oracle-reported loss metrics. An arbitrage-free valuation framework is developed under an incomplete market setting using the minimal martingale measure, while sponsor-optimal contract design is formulated under a dual-measure framework. Empirically, crypto loss dynamics are modeled using generalized extreme value distributions and copula-based dependence structures, whereas financial risk factors are modeled through ARIMA–GARCH and vine copulas. A smart-contract-enabled on-chain settlement architecture is further introduced to automate trigger evaluation and cash-flow execution. Findings Empirical results based on REKT crypto incident data demonstrate strong dependence between monthly extreme and aggregate losses, with heterogeneous dependence structures across blockchain ecosystems. Simulation studies show that trigger and principal repayment designs substantially affect bond price distributions and tail risk exposures. Conservative trigger structures generate more stable bond valuations, whereas aggressive structures exhibit greater downside dispersion. The proposed framework supports economically viable risk transfer while enabling transparent and timely settlement through blockchain-based execution. Originality/value This study develops, to the best of our knowledge, the first integrated framework for crypto native catastrophe bonds that combines arbitrage-free pricing, sponsor optimal contract design and smart contract-based on-chain settlement. Unlike traditional CAT bonds or cyber insurance-linked securities the proposed framework explicitly incorporates oracle-based observability, crypto-specific dependence structures and automated settlement, providing a novel mechanism for transferring systemic digital asset risks to capital markets.

Decentralized Finance (DeFi) lending protocols currently rely on heuristic, utilization-based bonding curves that mandate severe over-collateralization, systematically excluding under-collateralized assets like corporate invoices. This paper introduces a mathematically optimal pricing mechanism for decentralized credit: the Reverse Kelly Automated Market Maker (rkAMM), the core engine of our proposed lending framework. By inverting the Kelly Criterion, traditionally used for optimal bet sizing, we construct a dynamic interest rate discovery protocol that explicitly prices individual loan risk. The rkAMM ingests real-time Probability of Default (PD) streams from an off-chain Explainable AI oracle and dynamically calculates the exact interest rate required to sustain target liquidity provider (LP) yields. We mathematically derive the Reverse Kelly pricing function ($r = \frac{y + PD}{1 - PD}$), proving its strictly convex superiority over Aave and Compound's static utilization curves in managing capital efficiency. Furthermore, we deploy the rkAMM architecture via Solidity smart contracts, optimizing for gas-efficient 1e18 (WAD) floating-point arithmetic. To ensure decentralized transparency, our simulation infrastructure leverages MLflow for tracking yield hyperparameters, Data Version Control (DVC) linked to DagsHub for versioning Real-World Asset (RWA) data arrays, and localized edge-inference via Ollama (Llama-3) and Hugging Face (FinBERT) for zero-cost predictive modeling. Monte Carlo simulations across 10,000 macroeconomic stress scenarios confirm that the rkAMM maintains protocol solvency and stabilizes LP yields at 12-15\% net of expected credit losses. This work provides the foundational financial engineering required to bridge the \$2 trillion global supply chain finance gap using permissionless blockchain infrastructure.
Regional decentralization within the framework of regional autonomy in Indonesia often creates a regulatory vacuum regarding the ownership and management of assets resulting from cooperation between the central and regional governments. This study aims to analyze the provisions of Law No. 23 of 2014 on Regional Government and to identify regulatory gaps and models for resolving conflicts over public assets following decentralization. The research method employed is a normative legal approach using legislative, conceptual, case-based, and comparative analyses. The findings reveal that Law No. 23/2014 does not explicitly regulate the status of assets during the agreement period, mechanisms for the transfer of rights and obligations, ownership proportions from multi-source financing, or compensation for the parent region. Consequently, legal uncertainty arises regarding large-scale strategic assets involving third parties. This study also found that multi-party mediation involving the governor and the prosecutor’s office proved more effective in resolving public asset disputes than litigation, as demonstrated in the Tasikmalaya case. This study recommends revising Law No. 23/2014 by adding a special chapter on the transfer of assets resulting from post-decentralization cooperation and formalizing the involvement of the prosecutor’s office in the mediation of public asset disputes.
This research study investigates the evolution of the Taliban from an insurgent movement into a hybrid insurgent-state actor. Utilizing datasets from terrorism, conflict, and open-source intelligence, the paper analyzes the motivations, organizational structure, financing mechanisms, operational capabilities, targeting patterns, and governance practices of the Taliban. It assesses the group's transition from insurgency to a de facto government following its resurgence in Afghanistan and examines the implications for regional security, international recognition, sanctions compliance, and counterterrorism policy. The findings indicate that the Taliban's unique blend of centralized ideological leadership, decentralized operational execution, economic adaptability, and increasing diplomatic engagement poses a multifaceted challenge for contemporary security analysis and international governance frameworks.

Abstract: The idea of cryptocurrency is really interesting. It started as a money idea and now it is changing how the world thinks about money and technology. Cryptocurrency began with Bitcoin in 2008. Now it includes ideas like blockchain and special kinds of contracts. There are also kinds of money from central banks and unique digital things called NFTs. This paper looks closely at the technology behind cryptocurrency. How it affects the economy, people and laws. It talks about the things that cryptocurrency can do which will probably help it grow. It also talks about the problems that cryptocurrency is facing which might slow it down. The paper looks at what might happen with cryptocurrency in the future and how it will affect the world and money systems. After looking at a lot of research from 2008 to 2023 it seems that cryptocurrency is a concept that could be really big, in the future. For it to really work some technical and other issues need to be figured out. Cryptocurrency has to deal with these issues to be sustainable. The idea of cryptocurrency is still very promising. It needs to solve some problems.. Keywords: Cryptocurrency, Blockchain Technology, Decentralized Finance (DeFi), Smart Contracts, Consensus Mechanisms

This article examines whether the use of stablecoins as instruments for financing agribusiness produces civil-liability imputation gaps that are incompatible with traditional dogmatic assumptions. Through a hypothetical-deductive method and a dogmatic-functional approach, the study analyzes stablecoins, tokenized agribusiness financing, decentralized finance, and comparative regulatory frameworks in the European Union, the United States, and Brazil. It argues that the operational decentralization promoted by stablecoins fragments the poles of liability, weakens linear causation, and renders the classical fault paradigm insufficient. The article proposes an interpretive model based on three pillars: layered proportional liability, duties of governance and due diligence, and accountability as an autonomous criterion of imputation. It concludes that civil liability has the dogmatic resources necessary to respond to the tokenized economy, provided that causation, fault, and risk are reconstructed in light of the structural complexity of blockchain-based arrangements.
Blockchain technology has moved from the fringes of cryptographic research into the center of serious conversations about how industries govern data, verify transactions, and establish trust between parties who have no prior relationship and no shared authority to appeal to. Yet for most professionals working in management, finance, healthcare, and logistics, the technology remains opaque — described in either overly technical language that assumes a computer science background, or in breathless promotional terms that obscure more than they reveal. This paper is an attempt to close that gap honestly. Drawing on a progressive self-directed engagement with blockchain fundamentals, this work develops a conceptual framework covering four interconnected dimensions: its foundational governance philosophy of decentralization and equal network rights; its cryptographic security architecture, encompassing public and private key pairs, symmetric and asymmetric encryption, and hash-based data integrity; its distributed node network, comprising full nodes, lightweight nodes, and mining nodes and their respective governance roles; and its real-world application domains across supply chain management, healthcare information systems, financial services, human resources verification, and artificial intelligence data integrity. The paper adopts a conceptual analysis methodology, synthesizing foundational and applied blockchain literature to construct an integrated framework accessible to management researchers and practitioners. The central argument is that blockchain's significance is not primarily technological but institutional: it represents a structural alternative to the centralized authority model that has governed data ownership and transactional trust for centuries.

Abstract We investigate the sustainability of a carry trade approach on AAVE V3, in which USDC is lended and used as collateral and Wrapped Ether is obtained by borrowing. We extend the Cox-Ingersoll-Ross model by incorporating Poisson-Exponential jumps to account for abrupt rate surges which can be seen on Decentralized Finance lending platforms. Using Monte Carlo simulation with 10,000 paths, we estimate liquidation probabilities. The approach takes into account compounding interest, price fluctuations for the borrowed asset, and the liquidation mechanics of AAVE V3. We use hourly data from January 2023 to January 2026 to estimate the model parameters for USDC and WETH, more specifically variable lending and borrowing rates. Our empirical results show that the average USDC supply rate (4.98%) exceeds the average WETH borrow rate (2.86%), yielding a positive spread 76% of the time. Even with WETH price appreciation from $1,381 to $4,926 during the sample period, the strategy yields a low probability of liquidation and positive expected returns. The 1-year liquidation probability is approximately 6.1-7.0% at depending on starting LTV and model used, with positive mean P&L for non-liquidated paths and mostly profitable paths. Our findings demonstrate that a profitable carry trade can be carried out on DeFi platforms using stablecoins as collateral and that these positions are sustainable.
Abstract Bitcoin was the breakthrough innovation demonstrating peer-to-peer transfer of value without a central bank and has since expanded to countless innovations such as smart contract applications, decentralized finance protocols and asset tokenization. The EU is moving from scattered state-specific rules governing cryptocurrency activities to a coherent European regulatory regime. This paper review the transition to a harmonized framework in 2024-2025 from a doctrinal-institutional perspective, unpack how to carry out the three main legislative instruments: MiCA, TFR on information accompanying transfers of funds and transfers of certain crypto-assets and amending the EU directive and the EU AML package . Moreover, I look at the implications of DAC8 for the tax treatment of crypto-assets and tokenized assets. In 2025, the market begins institutionalizing, as MiCA requires significant compliance measures in terms of governance, transparency and conduct for CASPs to get licensed. Moreover, in conjunction with the new TFR rules, compliance for CASPs, at least in the business models discussed, effectively transforms into an operational infrastructure issue revolving around data quality, process efficiency and interoperability. By way of comparison, I analyze eight example business models in eight representative EU markets that appear to be impacted. These include: two major exchanges, two broker-dealers offering cryptocurrency on trading platform, a provider of non-custodial software wallets, two DeFi protocol participants and two NFT platform providers. These fall into three general categories depending on their legal status, direct regulatory burden and level of engagement with decentralized technologies. Finally, harmonized regulatory frameworks like the one outlined for the EU increase operational fixed costs and favor consolidation, reduce the benefits for regulatory arbitrage and thereby boost user protection, although part of innovation may pivot towards B2B solutions.
Abstract Smart contracts are the fundamental building block of decentralized applications (DApps) and decentralized finance (DeFi). However, their immutability makes security flaws exceptionally costly. Despite advancements in vulnerability detection, such as static and dynamic analysis, formal verification, and Solidity language improvements, vulnerabilities continue to result in substantial financial losses, exceeding $2 billion in 2024 alone. This paper presents a comprehensive analysis of smart contract vulnerabilities derived from real-world exploits, systematically categorized into seven distinct types. Each category is illustrated with Solidity code examples and insights from notable exploits. An Enhanced test suite is developed by restructuring the existing solidity-defects-and-bugs suite and supplementing it with new smart contract implementations to address underrepresented vulnerabilities, including flash loan and price oracle manipulation. We evaluate three widely used analysis tools (Slither, Mythril, and 4naly3er) on both the original and Enhanced suites, revealing substantial limitations in detection coverage. To address these limitations, we introduce the Solidity Defects and Bugs Analysis (SDABA), which incorporates advanced analyses and detectors to identify 28 vulnerability variations across both suites. Results on the SDB and Enhanced test suites show that SDABA improves overall precision, recall, and F1-score compared with the evaluated tools. Finally, we release the source code, test suite, and vulnerability reports to support future research in smart contract security.
Climate change presents intensifying environmental, economic, and social challenges, particularly for developing countries such as India, where climate vulnerability intersects with pressing developmental priorities including energy access, poverty alleviation, and sustainable urbanization. While global frameworks such as the United Nations Framework Convention on Climate Change (UNFCCC) and the Paris Agreement establish mitigation and adaptation targets, their effectiveness depends significantly on decentralized and community-driven implementation. In this context, community-based climate solutions (CBCS) have emerged as an important bridge between national policy commitments and localized climate action. This paper examines India’s renewable energy transition and electric mobility initiatives as examples of decentralized climate governance. Renewable energy programmes implemented by the Ministry of New and Renewable Energy, especially rooftop solar expansion and the PM-KUSUM scheme, promote distributed power generation, solar irrigation, and farmer-centric energy systems. These interventions contribute not only to carbon emission reduction but also to rural income diversification, agricultural resilience, and enhanced energy security. By encouraging local ownership and participatory models, such programmes integrate climate mitigation with inclusive development objectives. Complementing these initiatives, electric mobility policies advanced by the Ministry of Heavy Industries, including the PM E-Drive scheme, support the adoption of electric two-wheelers, three-wheelers, and public transport systems. These measures reduce urban air pollution, lower fossil fuel dependence, and create green employment opportunities within emerging clean energy value chains. The diffusion of electric mobility further demonstrates how local entrepreneurship, cooperatives, and community participation can accelerate low-carbon transitions. By situating these initiatives within a community-based governance framework, the study argues that decentralized renewable energy systems and electric mobility expansion reinforce climate mitigation and adaptation while promoting socio-economic empowerment. The analysis concludes that India’s evolving climate strategy reflects a gradual shift toward participatory and multi-level governance models. Strengthening institutional coordination, expanding climate finance access, and enhancing local capacity-building remain essential to sustaining and scaling community-based climate action in alignment with global climate commitments.
The rapid transformation of financial systems requires secure and intelligent architectures capable of supporting predictive analysis, decentralized operations, and collaborative knowledge exchange. Traditional banking infrastructures often depend on centralized data management, creating challenges related to privacy risks, limited interoperability, and restricted cross-entity collaboration. This research proposes a Decentralized Banking Network (DBN) designed to integrate blockchain-based distributed systems, predictive assessment mechanisms, and secure knowledge-sharing capabilities. The proposed framework enables financial institutions to collaboratively analyse data while maintaining ownership and confidentiality of sensitive information. The architecture combines distributed ledger technology, intelligent prediction models, and decentralized governance mechanisms to improve financial decision-making. Blockchain concepts provide transparency and trust among participating entities, while predictive assessment techniques support risk evaluation, fraud detection, and strategic planning. The theoretical foundation of this research is derived from distributed ledger systems, decentralized control, and federated financial intelligence. Distributed ledger technology provides mechanisms for secure and transparent transactions across independent participants (Sunyaev and Sunyaev, 2020). Recent developments in federated financial ecosystems demonstrate the potential of decentralized analytics for improving risk assessment while maintaining data sovereignty (Arifin Shawn et al., 2025). The proposed network highlights how decentralized banking models can improve security, collaboration, and predictive accuracy. However, challenges related to scalability, regulatory compliance, computational complexity, and governance remain significant considerations. This research provides a conceptual framework for future banking ecosystems where institutions can achieve secure knowledge sharing without compromising confidential financial information.

Decentralized finance has disrupted the lending process by transferring the intermediary role from institutionally-led balance sheets into a public ledger framework of smart contracts, pooled liquidity, and tokenized governance. The relevance of such a change in the lending paradigm is more of a question of different trust mechanisms, where the solvency of actors can be maintained through the imposition of collateral and automated processing [1][3]. A qualitative comparison is made below through a literature-constrained synthesis of five sources on DeFi architecture, flash loan exploits, lending protocol structure, decentralized governance flaws, and extractable value [1]-[5]. The two protocols of Aave and Compound have been selected for being representative DeFi lending cases, as per the allowed literature that points them out to be the top loanable funds protocols, having liquidity pools and variable rates [1][3]. This comparison is made against CeFi as an institution-driven reference point rather than other DeFi lending protocols owing to the asymmetry of the evidence base. Three conclusions are drawn.Second, the risk architecture of DeFi lending is structurally different from other financial institutions in that flash loans, dependence on oracle feeds, smart contract weakness, composable nature, extractable value, and governance capture are not mere flaws in DeFi but inherent aspects of open and highly coupled financial systems [2][4][5]. Third, governance in DeFi is an additional security mechanism, as the governance of protocol control, parameters and responses to emergencies rests on the robustness of token-based decision-making mechanisms [4].
The aim of this research is to analyze the impact of Decentralized Finance (DeFi) platforms on the competitiveness of Iraqi private banks on the basis of the relationship between DeFi and the dimensions of competitiveness which are represented by operational efficiency, financial innovation and market share. This study used descriptive-analytical approach, and A questionnaire was distributed to employees of Iraqi private banks, who constituted the study sample and The study sample consisted of employees of Iraqi private banks. The data were analysed statistically with the SPSS software by appropriate statistical methods like correlation coefficient and regression analysis. The results of the research showed a positive and significant relationship between decentralized finance and banking competitiveness. In addition, the result of the regression analysis showed that the DeFi platforms had a significant effect on competitiveness, accounting for 59.2% of the variance (R-squared). The findings clearly show that decentralized finance helps to increase the operational efficiency and improve financial innovation, but with a moderate effect on market share. The study calls for Iraqi banks to embrace financial technology (FinTech) and improve their digital framework. Further, they need to be innovative and partner with FinTech firms to strengthen their competitive edge, given the fast pace of digital transformation.
This technical report provides an empirical evaluation of Bitcoin Layer-2 execution environments (BOB, Bitlayer, Citrea, Stacks, and Rootstock) against a six-layer architectural framework designed for institutional-grade decentralized finance (DeFi). Using Tage_Root — a purpose-built reference implementation operationalizing Bitcoin-native execution (L1) and trust-minimized bridging (L2) — the analysis assesses conditions required for credible BTC-denominated yield markets, including intent-based routing, autonomous capital allocation, zero-knowledge compliance, and accountable governance. The findings reveal that while several systems have substantially solved the bridge problem at the technical level, critical higher-layer infrastructure remains absent or weak. This architectural gap explains the persistent idleness of bridged BTC and the low capital efficiency observed in BTCFi protocols, despite significant growth in bridging capacity. The report offers a code-grounded diagnostic benchmark and lays the empirical foundation for forthcoming theoretical work on the “Bridge Problem” and the pricing of Bitcoin-denominated yield. It argues that trust-minimized execution alone is insufficient for institutional capital formation in Bitcoin DeFi.

This paper examines the fiscal impacts of climate-related events in the Philippines and proposes policy measures to build a climate-resilient economy. Through cross-sectional analysis, it finds that the fiscal resilience of local government units (LGUs) is influenced by their dependence on external revenues, the availability of preallocated funds, and the severity of disasters. The results underscore the need for region-specific fiscal strategies that diverge from conventional frameworks, given the country’s decentralized disaster management system and the pivotal role of local institutions. The study recommends establishing a dedicated climate resilience fund, adopting climate-responsive budgeting, strengthening risk transfer mechanisms, incentivizing green investments, and enhancing LGU capacity to manage adaptation financing. Additionally, investments in climate research, data-driven governance, and public awareness are essential. Aligning climate finance with long-term development goals and the 2030 Agenda for Sustainable Development would integrate resilience into national planning, enabling the Philippines to better withstand climate risk while promoting sustainable growth and fiscal stability.
Since the 1980s, decentralization has improved local development adaption in a number of sub-Saharan African nations. However, in recent decades, this approach of autonomous local administration has encountered challenges, such as a decline in funding. However, Côte d'Ivoire's Law No. 2003-208 of July 7, 2003, on the transfer and distribution of state competencies to local authorities, permits local elected officials to mobilise funds locally by establishing revenue-generating ventures in a number of industries, including tourism. How can local tourism support local development in Côte d'Ivoire's decentralized villages given the country's diminishing financial resources? The goal is to demonstrate how local tourist marketing may serve as a lever for funding local development in the dynamic of enhancing living standards. 200 household heads in neighbourhoods chosen by reasoned choice participated in a questionnaire survey, field observation, direct and semi-direct interviews, and documentary research as part of an empirical method. The municipality of Seguela seems to be brimming with a variety of tourism opportunities. To highlight these potentialities, local officials have undertaken to boost local tourism through the opening of roads, the improvement of potable water supply and electrification, the creation of public spaces for tourist attraction, the cleaning of gutters and street sweeping, and especially the establishment of the "Worodougou Lôgôba" festival, etc. These municipal investments have resulted in: the commercialisation of agricultural products and local cultural craftworks, the emergence of various means of mobility, the attraction of customers to restaurants, maquis, and hotels; thus creating direct and indirect jobs. Due to the increased foreign cash earned by tourist taxes, this has made it easier to optimise local budgetary resources.
Blockchain technology has transformed digital transactions by providing decentralized, immutable, and transparent ledgers that eliminate the need for centralized intermediaries. However, the inherent transparency of blockchain networks often exposes sensitive transaction details, creating significant privacy concerns for users and organizations operating in sectors such as finance, healthcare, supply chain management, and digital identity management. Balancing transparency with confidentiality has therefore become a critical challenge in the evolution of blockchain systems. Zero-Knowledge Proofs (ZKPs) have emerged as a revolutionary cryptographic solution that enables one party to prove the validity of a statement without revealing the underlying confidential information. This paper proposes a comprehensive framework for integrating Zero-Knowledge Proof mechanisms into blockchain systems to enhance transaction privacy while preserving transparency, security, and verifiability. The framework incorporates advanced cryptographic protocols, including zk-SNARKs and zk-STARKs, together with decentralized consensus mechanisms to achieve secure and efficient verification of blockchain transactions. The proposed approach evaluates system performance in terms of privacy preservation, computational efficiency, scalability, verification accuracy, and transaction throughput. The findings indicate that Zero-Knowledge Proof-based blockchain architectures significantly improve user privacy, reduce information leakage, strengthen security against malicious attacks, and maintain the transparency and integrity required for decentralized trust. The proposed framework provides a scalable and secure foundation for next-generation blockchain applications requiring both confidentiality and public verifiability.
Decentralized finance systems manage vast assets without central authority, creating a borderless economy that defies traditional legal boundaries. While fostering innovation, this independence invites global criminal activities, as perpetrators exploit automated, anonymous smart contracts to evade detection. Current international legal frameworks remain ill-equipped to address the complexities of cross-border digital fraud or assign liability within immutable, machine-run protocols. This research examines the jurisdictional conflicts and attribution challenges inherent in decentralized financial systems. Utilizing a qualitative doctrinal analysis of recent legislative initiatives and international legal standards, this article evaluates the viability of a functional equivalence model for assigning criminal responsibility. The findings suggest that harmonizing global regulatory requirements is essential to bridge the gap between technical execution and legal accountability. This study proposes a framework that integrates human-led dispute resolution with automated transparency to ensure stability, protect market participants, and foster long-term confidence in the global digital economy.
