As the global economy continues to grow, more companies are outsourcing their logistics activities to third-party logistics (3PL) providers. This is because consumers have a high demand for various types of goods delivery, \nincluding for small and large packages, light and heavy items, and so on. As a result, package delivery services have become more competitive, offering a range of services to meet these diverse needs. However, this increase in competition has also made it more important for consumers to carefully consider their options and choose a delivery service that is efficient,cost-effective, and reliable. The solution is to use a logistics recommendation system and smart contracts that allow consumers to easily determine and order logistics services according to their needs. Therefore, in this study the author want to state that this paper as proposed paper.

Social distancing has been implemented to stop the COVID-19 outbreak, which is currently a major public health concern on a global scale. Telemedicine is used by medical professionals to monitor their patients, especially those with chronic diseases. However, various implementation-related risks, including data breaches, access restrictions within the medical community, inaccurate diagnoses etc., are faced by traditional telemedicine. We proposed the enhanced decentralised smart healthcare system (DSHS) to reduce the risks associated with traditional telemedicine healthcare solutions that utilise blockchain-based smart contracts to monitor, supervise, and carry out transactions. An immutable Modified Merkel tree structure is used to hold the transaction for viewing and accessing revocation contracts on a public blockchain, updating and sharing patient health records with all entities. Performance evaluation is done on the Ethereum platform. The simulation results show that the proposed framework outperforms existing telemedicine solutions by enhancing transparency, boosting efficiency, and reducing average latency in the system.

This paper investigates the relationship between national culture and the early adoption of Bitcoin. Utilizing a dataset comprised of Google Trends data on Bitcoin search interest for 64 countries, we construct measures of early Bitcoin adoption and examine their correlation with Hofstede's cultural dimension scores. Our findings reveal that in developed countries, lower Masculinity and Long-Term Orientation are associated with earlier Bitcoin adoption. In contrast, developing countries with lower Indulgence are found to adopt Bitcoin early. This paper contributes to the literature by highlighting how different cultural traits, moderated by a country's development status, can influence the Bitcoin early adoption.

Das Ziel dieser Bachelorarbeit ist die Darstellung von Techniken zur Verfolgung von Transaktionen und Entitäten auf der Bitcoin Blockchain. Die zugrundeliegende Forschungsfrage lautet wie folgt: Welche Aussagekraft und Grenzen haben Heuristiken und Analysemethoden zur Nachverfolgung von Bitcointransaktionen und wie wirken sie sich auf deren Anonymität aus? Zur Beantwortung der Forschungsfrage wird eine Literaturrecherche durchgeführt. Die Funktionsweise der Methoden wird dargestellt, Stärken und Schwächen der Methoden werden aufgezeigt und gegebenenfalls Verbesserungsvorschläge gemacht. Es zeigt sich, dass die Anonymität des Bitcoin-Systems aus verschiedenen Richtungen eingeschränkt werden kann. Die vorgestellten Analysemethoden haben jedoch ihre Grenzen und können die Anonymität des Bitcoinsystems nicht endgültig überwinden. Letztendlich bleibt festzuhalten, dass die Anonymität eines Nutzers von seiner Bitcoin-Nutzung und der Nutzung seines Umfelds abhängt. Ein bewusster, anonymer Umgang mit der Kryptowährung ist die Grundlage für eine solide Privatsphäre.

This paper considers introducing asymmetric privacy in the design of central bank digital currencies (CBDC) and digital currencies more generally to preserve the privacy of money spent while keeping the benefits of digital records for money received. It is shown that this feature would help minimize real distortions between consumers, firms, and financiers while enabling tax optimization and better access to external financing. Protecting the privacy of consumers is desirable from a welfare and efficiency standpoint as long as there exist noticeable privacy concerns. Implementing asymmetric privacy is technologically feasible, using, for instance, zero-knowledge proofs or other privacy tools. This paper has been accepted by Lin William Cong for the Virtual Special Issue on Digital Finance. Supplemental Material: The online appendix is available at https://doi.org/10.1287/mnsc.2024.06830 .

Purpose This paper aims to investigate optimal anti-counterfeiting strategies for non-fungible token (NFT) platforms in decentralized digital marketplaces. Using a game-theoretic model, it analyzes how verification policies shape interactions among platforms, genuine creators, counterfeiters and consumers. Addressing a theoretical gap, the study models the incentives and trade-offs platforms face when deciding whether and how much to verify product authenticity. It evaluates the impact of these decisions on consumer surplus and creator welfare, providing insights for platform operators and regulators seeking to balance profitability, authenticity and stakeholder interests. Design/methodology/approach A game-theoretic model examines strategic interactions among NFT platforms, genuine creators, counterfeiters and consumers across varying verification levels. The model incorporates dual sales channels (authentic and dubious), platform commissions and consumer heterogeneity in quality preference. By solving for subgame perfect equilibria, the analysis reveals how verification intensity influences counterfeiter entry, pricing and welfare outcomes. Comparative statics and equilibrium analysis provide managerial implications. The framework highlights the trade-offs platforms face in balancing verification costs with consumer trust and marketplace efficiency. Findings The study reveals counterintuitive results. First, the relationship between verification intensity and counterfeiter entry is non-monotonic – moderate verification can increase counterfeit activity by softening price competition between the dual channels. Second, stronger verification may reduce consumer surplus as price increases outweigh trust benefits. Third, the optimal verification level depends on verification costs and commission structures. Moderate verification often emerges as optimal, while excessive verification can harm both consumers and genuine creators. Research limitations/implications This study contributes to the literature on digital platform governance and anti-counterfeiting by introducing a formal game-theoretic model tailored to decentralized NFT marketplaces. It advances understanding of how verification strategies influence market structure and welfare outcomes in environments with limited enforcement. The findings challenge conventional views that stronger verification always benefits consumers and sellers, revealing nuanced trade-offs in decentralized platforms. These insights provide a foundation for future research on optimal platform design and regulation in blockchain-enabled, trust-sensitive digital ecosystems. Practical implications This paper offers actionable guidance for NFT platform managers in designing effective anti-counterfeiting strategies. It reveals that moderate verification – rather than maximal enforcement – is often optimal, even without cost constraints, as excessive verification can unintentionally reduce consumer surplus and original creator welfare. The findings highlight the importance of aligning verification intensity with platform commission structures. Regulators are also advised to consider incentive-compatible policies that promote trust while preserving market participation. These insights support more balanced and efficient governance in decentralized digital marketplaces. Social implications This study highlights the broader societal impact of anti-counterfeiting strategies in decentralized digital economies. It shows that well-intentioned verification efforts may unintentionally harm consumers by increasing prices and limiting access to authentic digital goods. The findings call for a more nuanced understanding of how policy and platform design affect consumer welfare, creator livelihoods and digital trust. By emphasizing the trade-offs between authenticity and accessibility, the study informs policymakers and platform designers about the importance of inclusive, efficient verification mechanisms that protect stakeholders without stifling innovation or participation in the rapidly evolving NFT and blockchain ecosystems. Originality/value This study fills a theoretical gap by modeling decentralized NFT marketplaces with limited enforcement and uncertainty. It is among the first to analyze anti-counterfeiting strategies in this context, offering practical guidance for platform operators and regulators. The findings enrich digital platform governance literature by highlighting nuanced trade-offs in verification strategies.
