Cryptocurrency, powered by blockchain technology, is transforming retail finance by introducing decentralized payment systems and alternative financial instruments. This study examines the technological, economic, behavioral, and regulatory factors influencing cryptocurrency adoption among consumers and businesses. Cryptocurrencies such as Bitcoin, Ethereum, and stablecoins offer benefits including faster transactions, cross-border payments, greater transparency, and reduced reliance on centralized intermediaries. However, challenges such as price volatility, regulatory uncertainty, cybersecurity risks, limited merchant acceptance, and low consumer awareness continue to hinder widespread adoption. Using a conceptual research framework, the study analyzes factors such as perceived usefulness, security, trust, ease of use, financial benefits, and regulatory support. The findings indicate that cryptocurrency adoption is gradually shifting from speculative investment toward practical applications, including digital payments, cross-border settlements, loyalty programs, and decentralized financial services. Stablecoins and blockchain-based payment solutions show greater potential for retail finance due to their stability and usability. The study concludes that successful cryptocurrency integration requires a balance between innovation, security, regulatory compliance, and consumer trust, while improved regulations and financial education are essential for sustainable adoption.

An emerging healthcare delivery model is enabling a new era of clinical care based on well-informed decision-making processes. Current healthcare information systems (HISs) fall short of adopting this model due to a conflict between information security needed to implement the new model and those already enforced locally to support traditional care models. Meanwhile, in recent times, the healthcare sector has shown a substantial interest in the potential of using blockchain technology for providing quality care to patients. No blockchain solution proposed so far has fully addressed emerging cross-organization information-sharing needs in healthcare. In this paper, we aim to study the use of blockchain in equipping struggling HISs to cope with the demands of the new healthcare delivery model, by proposing HealthyBlockchain as a granular patient-centered ledger that digitally tracks a patient’s medical transactions all along the treatment pathway to support the care teams. The patient-centered ledger is a neutral tamper-proof trail time-stamp block sequence that governs distributed patient information across the decentralized discrete HISs. HealthyBlockchain connects patients, clinicians, and healthcare providers to facilitate a transparent, trustworthy, and secure supporting platform.

As an important part of China's national economy, small and medium-sized enterprises (SMEs) play an important role in promoting China's economic growth, expanding jobs and increasing national tax revenue. However, due to the small scale of SMEs, low level of credit, lack of collateral, they are often plagued by narrow financing channels, financing difficulties and expensive financing, so a new technology is urgently needed to solve the current financing plight of SMEs. In recent years, block chain technology has attracted wide attention worldwide due to its decentralized and trustfree technical mechanism, and has become another new thing that can be popularized and applied on a global scale after the Internet. In this paper, "block chain" and "finance" are perfectly combined, aiming to use the properties of decentralization, immutability and traceability of block chain technology to improve the credit level of small and medium-sized enterprises and expand their financing channels. It is expected to effectively solve the financing difficulties of small and medium-sized enterprises, promote the sustainable and healthy development of small and medium-sized enterprises, and make greater contributions to the national economic growth.

This paper surveys the current status of blockchain technologies integration and its potentials with enterprise systems’ (ES). The blockchain technology has received substantial attention since the recent cryptocurrency-boom. The corporate world seeks to stay on the blockchain-train by exploring how they can benefit from the evolving technology and platforms. Hence, this research explores the capabilities and potentials of blockchain technology illustrated in the extant literature and investigates how it can reinforce, and be integrated with enterprise systems through semi-structured interviews with subject matter experts. The literature and collected data were classified into four components of blockchain technologies; identity, assets, logistics, and transactions. Our main findings suggest that there is scarce literature on blockchain integration with ES. Nevertheless, there is a huge potential for this integration, specifically on the transactions, identity, and logistics dimensions. In addition, our interview results suggest that blockchains can reinforce ES by accomplishing a single source of truth, and a common environment for shared information amongst a larger scope of actors and organizations.

As one of the disruptive technologies in the fourth industrial revolution, Blockchain has irrevocably changed how people live and work. Many scholars have studied the Blockchain, and the number of related publications has increased over time. Bibliometrics is an excellent method to study the development trend of a specific field. However, few scholars have used bibliometrics to research Blockchain; the inheritance and evolution among its different research themes have not yet been fully understood. This study emphasizes the scientific evolution and research focus of Blockchain through bibliometric analysis. We analyzed 2993 publications from 2014 to 2020 using co-word analysis and cluster analysis with bibliometric tools such as the SciMAT. The most productive author, country, institutions and leading research areas were identified, outlining the Blockchain field's fundamental developments. The results show the changes in keywords regarding Blockchain summarize the research hotspots in different periods. The study discusses the evolution process of various themes in each period, providing a meaningful reference for scholars to identify research hotspots and future research directions in the Blockchain field.

A blockchain features an immutable, encrypted, and distributed ledger that enables transactions even if trust and trusted intermediaries are absent. Despite research on their technological properties, few papers are on record to demonstrate (a) what business scenarios blockchains can enable and (b) under which circumstances they outperform rival technologies. This shortfall of design knowledge obscures blockchains’ value proposition, its conceptual limitations, and its positioning towards rival classes of IT artifacts. We set out to design a blockchain-based IS that enables pay-per-use business models for industrial equipment—a business model that suffers from high transaction costs and complex agency dilemma caused by asymmetric information. We demonstrate how smart contracts deployed in a blockchain can level these information asymmetries. However, we also find that blockchains will only outperform rival technologies if the business scenario fulfils a set of specific properties, narrowing down the scope of application scenarios for applying blockchains substantially.

Summary Motivation Most low‐ and middle‐income countries face an urgent need to scale up sustainable finance for low‐carbon and climate‐resilient infrastructure investment, yet underdeveloped capital markets tend to inhibit domestic resource mobilization for infrastructure investment. At the same time, domestic savers face a scarcity of “safe” local‐currency assets, resulting in the export of capital. Purpose This article explores options for mobilizing domestic savings through financial technology (fintech) solutions to scale up sustainable investment. Methods and approach The article discusses how fintech can help to complement conventional capital markets and mobilize financial resources for sustainable infrastructure investments. Findings The article puts forward a proposal for blockchain‐based project bonds to raise finance through a digital crowdfunding platform which is able to record transparently and certify the use of proceeds, sustainability impact, and revenue streams of projects by combining timestamp, public and private key mechanisms, and smart contract technologies. Policy implications The proposed approach would not only provide investors of different sizes with the opportunity to purchase local‐currency assets and issuers such as municipalities to raise funds for sustainable infrastructure investment, it would also facilitate project management once the project is operational, for example through metering and billing, and create full transparency over the life cycle of the investment, reducing problems concerning the misuse of funds.

“Smart Contracts” are tools based on distributed ledger technologies deployed in order to increase the efficiency of transactions. Their adoption is growing at an exponential scale due to the undisputable advantages brought by their property of self-executing tasks, yet on the opposite it raises concerns since it does not require any sort of moral scrutiny. In our paper we first address how the current ethical discussion can be framed in Decentralized Ledger Technologies, then we unfold the evolution in legal theory of a decentralized approach – epitomized by the motto “code is law” – finally we focus on “smart contracts” discussing the application of “engineering ethics” or the implementation of “ethical oracles”. At the end we conclude with a few remarks and some perspectives for future research.

A adoção de blockchain e contratos inteligentes tem se demonstrado uma opção valiosa para organizações inovarem em seus sistemas de informação. Nesse sentido, presencia-se também uma adesão ao desenvolvimento open source por parte dos envolvidos em tal ecossistema de soluções, especialmente com base na plataforma Ethereum e no uso do GitHub. Porém, apesar da presença de pesquisas prévias com foco na manutenção de contratos inteligentes, constata-se uma lacuna de pesquisa quanto 1) a análise do efeito que o processo de deploy na Ethereum exerce sobre os projetos open source em termos colaborativos e 2) na compreensão sobre o que efetivamente mudou nos repositórios após tal processo. Como fruto de uma pesquisa em andamento, este artigo contribui ao discutir um desenho de pesquisa exploratório pautado em Mineração em Repositórios de Software para compreender o efeito do processo de deploy na Ethereum em repositórios open source de contratos inteligentes.

Blockchain technology has gained increasing attention from research and industry over the recent years. This interest is mainly due to its core property that allows users to perform transactions without a Trusted Third Party (TTP), while offering a transparent and fully protected tracking of these transactions. However, there is a lack of reference models to describe and compare various Blockchain technologies, leading to some confusion between different kinds of solutions. We propose in this paper a reference model aiming to assess and compare different kind of Blockchain-based ecosystems, including Decentralized Applications (DApp).

Bitcoin is a social movement, which promises free and decentralized money, absent from the traditional regulatory institutions, but it can be challenging for financial industry regulators and other players in the financial markets. Thus, our study aims to analyze how the institutional voids manifest in the bitcoin institutionalization process as a currency. We adopt the institutional theory, from the perspective of institutional voids, in order to observe the concepts in emerging markets that show the difficulty or the beginning of the institutionalization of bitcoin as a currency. The institutional theory provides an opportunity to understand the reasons for using particular practices, actions, or manifestations. Our method is based on a qualitative exploratory approach with semi-structured interviews to understand how financial market experts perceive this phenomenon. Our results show that it is possible to identify how institutional voids manifest themselves, reinforcing the debate on whether bitcoin is, in fact, a currency.

Digital technologies are changing the business world at a rapid pace, bringing new challenges and opportunities for companies. This is especially true for blockchain technologies, which are increasingly being used to manage interorganizational transactions. Blockchains are distributed ledger technologies where data is replicated, shared, and synchronized over a network of computers without central servers. The main advantages of blockchains over standard contracts are that they are particularly secure, easily scalable, and comparatively inexpensive. At the same time, blockchains also present managers with a number of challenges in terms of network participation rules, control mechanisms, technology choices, and legal affairs. In this book chapter, we discuss these aspects and provide practical guidance for decision-makers. This discussion makes it easier for managers to determine whether and under what conditions blockchains offer an advantage for their business.

Abstract In this article, we explore the application of blockchain, a type of distributed ledger technology (DLT), in the field of energy trading. Specifically, we focus on crude oil trade. We argue that the application of blockchain technology and supplementary smart contracts supports responsible sourcing in complex supply chains and helps reduce information asymmetry in both the physical trade and paper trade of energy commodities markets. In order to apply blockchain technology to the energy market, we begin with a discussion on the architecture of blockchain and the different types of blockchain that might be applied in this sector. Further to this, we examine the current oil trading markets, particularly their relevant components, as part of the discussion on blockchain application. Subsequently, we look at how the various types of blockchain may be applied to the markets and examine their advantages and disadvantages. In conclusion, we look at the legal issues that may arise from such application, the potential solutions, and the potential impact of blockchain technology on the United Nations Sustainable Developmental Goals in the future and how a green fintech application can be developed.

Sensitivity of the health-related data and the focus on compliance and security has traditionally emphasized the need for centralized approach while implementing Electronic Health Records (EHR) systems. These one-institutional architectural designs are leading to fragmented and scattered pieces of valuable data across various data warehouses and silos. Interoperability challenges arise due to the absence of unified data management and exchange mechanisms making the social need for fundamental design changes bigger. The capability of a distributed ledger technology and blockchain to offer immutable, decentralized and cryptographically secured record of transactions throughout a peer-to-peer network can facilitate better collaboration and increased interoperability in the field of health and insurance information exchange processes. The paper examines different approaches and application of blockchain technology and identifies which implementations of components are more suitable and beneficial for the specific eco-system analyzed in the paper. This paper presents alternative way of dealing with information exchange across multiple stakeholders by justifying the use of decentralized approach, distributed access and solution how to comprehensively track and assemble health related data. We propose an architectural design and overview of a specific use case with focus on information exchange processes between health insurance providers and health care organizations, by using blockchain as an underlying technology. The architectural overview and data flows, backed up by sequence diagrams from specific use cases offered in this paper, can serve as a guide to the blockchain technology adoption and initial setup.
