Blockchain technology has been explored for governmental supervision of construction work (GSCW) due to its merits of traceability, immutability, and transparency. However, its decentralized nature is seemingly incompatible with GSCW, which is a type of centralized governance per se. This research aims to find a network topology with a proper level of (de)centralization and, based on this topology, to develop a blockchain-based model for GSCW. First, a literature review is conducted to identify problems in GSCW. Then, a cross-sectoral learning is performed between GSCW and digital currency electronic payment systems. Next, a design science research method is adopted to develop a dual-layer blockchain-based GSCW model integrated with an incentive mechanism. Finally, the model is illustrated in Hyperledger Fabric and its strengths and weaknesses evaluated. It was found that the model can enable an information-sharing, tamper-proof, and privacy-preserving mechanism without affecting the current status and routines of GSCW units and project teams. The model developed in our study can serve as a valuable reference for policymakers, practitioners, and researchers to develop governance policies or blockchain applications.

The construction industry is one of the largest industries in any country, contributing significantly to economic growth. A range of researchers explained that the construction industry suffered from numerous issues where financial issues are more critical. Late payments, cash flow issues, and lack of security of the payment are some of them. Blockchain technology shows a potential use for managing financial activities. Therefore, this research tends to investigate the applicability of blockchain technology to manage financial issues in the Sri Lankan construction industry. A comprehensive literature survey was carried out to assess the concept of blockchain technology and identified financial issues in the construction industry. A qualitative expert opinion survey was conducted with eight construction experts who had knowledge of the blockchain technology, selected through purposive sampling to collect data in a Sri Lankan context. The collected data was analysed using the content analysis method. The findings of the expert interviews indicated that faster transactions would help to reduce late payments; removing third parties from the transaction will reduce the involvement of many parties in the transaction process; and trust, security, transparency will help to increase foreign investments. Further, the lack of knowledge in the area, legal and tax issues, low investment, and social issues will be the challenges in adopting blockchain technology to the construction industry. The research finally suggests the ways to overcome such challenges in terms of using pilot projects, government rules and regulation. Thus, the research proposes that use of blockchain technology could minimise a significant number of financial issues in the construction industry.

Owing to the lack of research in emerging Asian nations, this research aimed to unearth the determinants of blockchain acceptance for supply chain financing by a Bangladeshi financing company called IPDC. Centred on a technology acceptance framework called UTAUT (unified theory of acceptance and use of technology) and open innovation research, an expanded model with a mediating variable is developed for this study. This research work employs the deductive inference method in conjunction with the positivism paradigm. A structural questionnaire was used to gather data, which were then processed through Smart-PLS (partial least square) for SEM (structural equation modeling). The survey includes all the people who are directly or indirectly involved in the supply chain financing platform of IPDC. The study consists of seven direct hypotheses and one mediating hypothesis. The results show that all the direct hypotheses except the impact of social influence on the behavioural intention to use (BINTU) blockchain are significant. The mediating hypothesis indicating the role of BINTU in the relationship between facilitating conditions (FCON) and the actual use of blockchain is also supported. FCON and BINTU together explain 88.7% variation in blockchain use behaviour for supply chain financing. The research advances past findings by employing an expanded UTAUT framework and validating observations with the other relevant studies throughout the world.
In recent times, organizations are increasingly adopting blockchain technology in their supply chains due to various advantages such as cost optimization, effective and verified record-keeping, transparency, and route tracking. This paper aims to examine the factors influencing the intention of small and medium enterprises (SMEs) in India to adopt blockchain technology in their supply chains. A questionnaire-based survey was used to collect data from 216 SMEs in the northern states of India. The study has considered an integrated technology adoption framework consisting of the Technology Acceptance Model (TAM), Diffusion of Innovation (DOI), and Technology-Organization-Environment (TOE). Using this integrated TAM-TOE-DOI framework, the study has proposed eleven hypotheses related to factors of blockchain technology adoption. Confirmatory factor analysis (CFA) and structural equation modeling (SEM) have been used to test the hypotheses. The results show that relative advantage, technology compatibility, technology readiness, top management support, perceived usefulness, and vendor support have a positive influence on the intention of Indian SMEs to adopt blockchain technology in their supply chains. The complexity of technology and cost concerns act as inhibitors to the technology adoption by SMEs. Furthermore, the three factors, namely, security concerns, perceived ease of use, and regulatory support, do not influence the intention to adopt the technology. The study contributes to filling a significant gap in the academic literature since only a few studies have endeavored to ascertain the technology adoption factors by supply chains of SMEs in a developing country like India. The study has also proposed a novel integrated technology adoption framework that can be employed by future studies. The findings are expected to enable SMEs to understand important factors to be considered for adopting blockchain technology in their supply chains. Furthermore, the study may benefit the blockchain technology developers and suppliers as they can offer customized solutions based on the findings.
Purpose This study aims to analyze the importance of disruptive technological innovations on qualitative service delivery and their impact on the investment banks’ employee performance. Design/methodology/approach The cluster sampling method has been used to collect the primary data from the 250 respondents from foreign investment banks. Variables used are employee performance, service delivery, technology, security, operations, strategy and quality through chi-square, linear stepwise multiple regression analysis and correlation. Findings Storage network, operating cost, client reporting, cloud system and money laundering are the highest and most significant predictors of employee performance. Employee performance multiplies every unit with a strategic solution owing to positive and robust correlation (0.944). Fusion technology-based banks offer quality service to their clients. Originality/value A combination of artificial intelligence and blockchain ensures increasing automation to improve efficiency and reduce the operating cost creating a seamless integration in fraud detection, customer support, risk management, security, digitization and automation process, algorithmic trading, wealth management, etc.
Banks attempt to invest in emerging financial technology (FinTech), such as blockchain, to enhance competitiveness. There is a great deal of literature on the technical and legal aspects of blockchain. However, there is little specific guidance on how banks can apply a holistic model to evaluate the blockchain-based business. This study proposes a hybrid decision model with confidence-weighted fuzzy assessments to address this valuable research topic. Supported by a group of seasoned experts, five major blockchain-based business models are evaluated for a domestic bank in Taiwan. The key findings contribute to understanding the importance of the involved factors and identifying the ideal business strategy for the bank. The result suggests that the most crucial dimension is policies and regulations, not the technical capability of banks.

BACKGROUND: In the collaborative business environment, blockchain coupled with smart contract removes the reliance on a central system and offers data integrity which is crucial when the transacting parties rely on the shared data. The acceptance of such blockchain-based systems is necessary for the continued use of the services. Despite many extensive studies evaluating the performance of blockchain-based systems, few have focused on users' acceptance of real-life applications. OBJECTIVE: The main objective of this research is to evaluate the user acceptance of a real-life blockchain-based system (BBS) by observing various latent variables affecting the development of users' attitudes and intention to use the system. It also aims to uncover the dimensions and role of trust, security and privacy alongside the primary Technology Acceptance Model (TAM)-based predictors and their causal relationship with the users' behavior to adopt such BBS. METHODS: We tested the augmented TAM with Trust Model on a BBS that comprises two subsystems: a Shopping Cart System (SCS), a system oriented towards end-users and a Data Sharing System (DSS), a system oriented towards system administrators. We set research questions and hypotheses, and conducted online surveys by requesting each participant to respond to the questionnaire after using the respective system. The main study comprises two separate sub-studies: the first study was performed on SCS and the second on DSS. Furthermore, each study data comprises initial pre-test and post-test data scores. We analyzed the research model with partial least square structural equation modelling. RESULTS: The empirical study validates our research model and supports most of the research hypotheses. Based on our findings, we deduce that TAM-based predictors and trust constructs cannot be applied uniformly to BBS. Depending on the specifics of the BBS, the relationships between perceived trust antecedents and attitudes towards the system might change. For SCS, trust is the strongest determinant of attitudes towards system, while DSS has perceived privacy as the strongest determinant of attitudes towards system. Quality of system shows the strongest total effect on intention to use SCS, while perceived usefulness has the strongest total effect on intention to use DSS. Trust has a positive significant effect on users' attitudes towards both BSS, while security does not have any significant effect on users' attitudes toward BBS. In SCS, privacy positively affects trust, but security has no significant effect on trust, whereas, in DSS, both privacy and security have significant effects on trust. In both BBS, trust has a moderating effect on privacy that correlates with attitudes towards BBS, whereas security does not have any mediating role between privacy and attitudes towards BBS. Hence, we recommend that while developing BBS, particular attention should be paid to increasing user trust and perceived privacy.

Purpose This paper presents a systematic literature review, including content and bibliometric analyses, of the impact of blockchain technology (BT) in auditing, to identify trends, research areas and construct an agenda for future research. Design/methodology/approach The authors include studies from 2010 to 2020 in their structured literature review (SLR), using accounting journals on the Scopus database, which yielded 40 articles with blockchain and auditing at its core. Findings One of the contributions of the authors’ analyses is to group the prior research, and therefore also the agenda for future research, into three main research areas: (1) Blockchain as a tool for auditing professionals to improve business information systems to save time and prevent fraud; (2) Smart contracts enabling Audit 4.0 efficiency, reporting, disclosure and transparency; (3) Cryptocurrency and initial coin offerings (ICOs) as a springboard for corporate governance and new venture financing. The authors’ findings have several important implications for practice and theory. Practical implications The results of this study emphasise that (1) the disruption of blockchain in auditing is in a nascent phase and there is a need for compelling empirical studies and potential for the involvement of practitioners; (2) there may be a need to reconsider audit procedures especially suited for digitalisation and BT adoption; (3) standards, guidelines and training are required to pivot towards and confront the challenge BT will represent for auditing; and (4) there are two sides to the BT coin for auditing, enthusiasm about the potential and risk upon implementation. These practical implications can also be seen as a template for future research in a quest to align theory and practice. Originality/value The authors’ SLR facilitates the identification of research areas and implications, forming a useful baseline for practitioners, professionals and academics, as they draft the state of the art on the disruption of blockchain in auditing, highlighting how BT is changing auditing activities and traditions.

The interest in the implementation of distributed ledger technologies (DLTs) is on the rise in the construction sector. One specific type of DLT that has recently attracted much attention is blockchain. Blockchain has been mostly discussed conceptually for construction to date. This study presents some empirical discussions on supply chain management (SCM) applications of blockchain for construction by collecting feedback for three blockchain-based models: project bank accounts (PBAs) for payments, reverse auction–based tendering for bidding, and asset tokenization for project financing. The feedback was collected from three focus groups and a workshop. The working prototypes for the models were developed on Ethereum. The implementation of blockchain in payment arrangements was found to be simpler than in tendering and project tokenization workflows. However, the blockchain integration of those workflows may have large-scale impacts on the sector in the future. A broad set of general and model-specific benefits/opportunities and requirements/challenges was also identified for blockchain in construction. Some of these include streamlined, transparent transactions and rational trust building, and the need for challenging the sector culture, upscaling the legacy information technology (IT) systems, and compliance with the regulatory structures.
This paper introduces an architecture to improve the pharmaceutical supply chain's security by using the Internet of Things, semantic web, and blockchain. This architecture increases transparency and visibility of drug flows and improves the representation of the increasing amounts of data that have been generated from pharmaceutical supply chain transactions. The pharmaceutical companies have problems dealing with the complexity of their supply chains, which represent the full life cycle of drugs from extracting raw materials, production, distribution, tracking of drugs, and quality assurance to use by patients. They need to create an efficient, effective, transparent, immutable, and secured supply chains to achieve a competitive advantage in a fast-changing market. A proposed architecture which applies the semantic web technology is implemented to enhance the representation capability of the IoT-blockchain based pharmaceutical supply chain data by annotating them with semantically rich languages to conduct formal reasoning, and aggregating data from heterogeneous sources in easy way and an interoperable manner. The proposed architecture integrates IoT, blockchain, and semantic web to help pharmaceutical companies improving their supply chains in transit and storage, improving patient satisfaction, trust through transparency, preventing drug counterfeit and sharing and reusing knowledge related to the pharmaceutical supply chain with other systems.
The utilization of energy in blockchain division is high as resource allocation models are using this technology and the rundown of resource utilization cases is continually developing. The communicated and permanent nature of blockchain innovation might be utilized to quicken the progressing change to increasingly decentralized and digitalized vitality frameworks and to address a portion of the difficulties the business is confronting in providing security in identification of authorized users and resource allocation transactions among the authorized users. The allocated resources to the users need to be recorded, otherwise the attackers may use them for malicious operations. In any case, blockchain is a developing innovation and it is viewed as a basic vulnerability by numerous users as the difficulties and chances of execution are still to a great extent. There is in this way an absence of information and shortage of dynamic gadgets for getting why, when and how the innovation can include significant worth. The proposed Resource Allocation for Authorized Users using Time specific Blockchain Methodology (RAAUTBM) performs resource allocation to authorized users to avoid malicious actions among blockchain-based use cases and increase practical information about how blockchain could be actualized. The RAAUTBM model verifies all the users for allotting access to the system. The proposed model allots the resources only to the authorized users and to identify the malicious users and remove them from the framework. The resources once allotted to a user remains for a time interval and then the resource is re-allotted to other authorized users for avoiding delay. Resource exchanges in this segment are known to be dull and wasteful, to a limited extent because of the absence of promoted straightforwardness. This research work centers around the advancement of a blockchain application that can improve the resource exchange procedure among authorized users. The proposed model is compared with the traditional methods and the results demonstrate that the proposed model is effective in allocating resources only to the authorized users.
The integration of digital technologies into business processes has a history of more than half a century. With the integration of technologies in the supply chain, businesses began benefiting from the possibilities as early as the 1970s. The emergence of ERP in the 1990s represents the beginning of a new era of the supply chain. Increasing competition and sustainability pressure have done businesses far from being sufficient on their own to respond to environmental conditions. This situation has made it necessary for companies to establish efficient supply chains. One of the main elements that ensure the efficiency of supply chains is that the flows in the supply chain can be monitored in real-time, and the problems that may arise can be intervened on time. Nowadays, businesses can obtain large amounts of data by integrating the Internet of Things technology into their business processes, can store and transfer this data more effectively with cloud computing technology, and can provide useful outputs for business goals with big data analytics. Especially in the last few years, blockchain opportunities have become more prominent. Businesses have begun to look for ways to gain gains by integrating this technology into the supply chain. In this study, the current academic situation in supply chain management has been revealed by the bibliometric analysis of studies published on the Web of Science. Important actors in the field were identified, and their primary contributions to the field were revealed. Content analysis of the terms used in related studies and the development and interactions of the concepts over time are among the research findings. Through this study, both a general phenomenon of the field and various predictions regarding the future directions it will take are provided.
Background: The healthcare industry is the new frontier for blockchain technology. Given its properties of immutability and decentralization, blockchain represents an opportunity for unprecedented level of privacy and security for all stakeholders by ensuring data integrity while giving patients control over their own health data. On a backdrop of rising interest in blockchain in general and blockchain healthcare applications in particular, there has been a proliferation of blockchain healthcare projects over the past few years. The aim of this review is to identify and understand real-world blockchain healthcare projects that have attained commercial success in the highly competitive blockchain market. Methods and findings: A scoping review was performed in January 2021 on all projects in the CoinMarketCap database. Following a pre-defined inclusion and exclusion criteria, eligible projects were selected. A single reviewer then reviewed each project's official website and whitepaper (where available) and performed data abstraction; 10 blockchain healthcare projects fulfilled the selection criteria. The review found that these projects made up 0.24% of the total number of actively tracked projects on CoinMarketCap. In terms of market capitalization, the total market capitalization for the projects was US$65,078,849, comprising less than 0.01% of the total market capitalization of all projects. Among the projects, the most frequent type was for personal health tracking. Conclusions: This review revealed that blockchain health projects currently comprise a small fraction of the overall number of commercially successful blockchain projects. However, because this sub-industry is still in its early stages, there are reasons to be optimistic that many more blockchain health projects will emerge and attain commercial success in future. Findings from this review done from an entrepreneurial perspective should help with the identification of future projects most likely to succeed.

BACKGROUND: In the era of big data, artificial intelligence (AI), and the Internet of Things (IoT), digital data have become essential for our everyday functioning and in health care services. The sensitive nature of health care data presents several crucial issues such as privacy, security, interoperability, and reliability that must be addressed in any health care data management system. However, most of the current health care systems are still facing major obstacles and are lacking in some of these areas. This is where decentralized, secure, and scalable databases, most notably blockchains, play critical roles in addressing these requirements without compromising security, thereby attracting considerable interest within the health care community. A blockchain can be maintained and widely distributed using a large network of nodes, mostly computers, each of which stores a full replica of the data. A blockchain protocol is a set of predefined rules or procedures that govern how the nodes interact with the network, view, verify, and add data to the ledger. OBJECTIVE: In this article, we aim to explore blockchain technology, its framework, current applications, and integration with other innovations, as well as opportunities in diverse areas of health care and clinical research, in addition to clarifying its future impact on the health care ecosystem. We also elucidate 2 case studies to instantiate the potential role of blockchains in health care. METHODS: To identify related existing work, terms based on Medical Subject Headings were used. We included studies focusing mainly on health care and clinical research and developed a functional framework for implementation and testing with data. The literature sources for this systematic review were PubMed, Medline, and the Cochrane library, in addition to a preliminary search of IEEE Xplore. RESULTS: The included studies demonstrated multiple framework designs and various implementations in health care including chronic disease diagnosis, management, monitoring, and evaluation. We found that blockchains exhibit many promising applications in clinical trial management such as smart-contract application, participant-controlled data access, trustless protocols, and data validity. Electronic health records (EHRs), patient-centered interoperability, remote patient monitoring, and clinical trial data management were found to be major areas for blockchain usage, which can become a key catalyst for health care innovations. CONCLUSIONS: The potential benefits of blockchains are limitless; however, concrete data on long-term clinical outcomes based on blockchains powered and supplemented by AI and IoT are yet to be obtained. Nonetheless, implementing blockchains as a novel way to integrate EHRs nationwide and manage common clinical problems in an algorithmic fashion has the potential for improving patient outcomes, health care experiences, as well as the overall health and well-being of individuals.

Blockchain has gained substantial recognition for its ability to induce transformation and innovation in existing business models and frameworks. Consequently, the application of this technology to the management domain and its processes has attracted increasing interest from academia and industry. Although research addressing the use of blockchain in management has gained momentum, this field presents a discontinuous overview of the current scope and boundary of the knowledge thereon. This study addresses this lacuna using bibliometric analyses to synthesize the prior literature. Data from Scopus 586 articles, entailing contributions from 72 countries, 273 journals, 1016 organizations, and 1284 authors, were analyzed. The findings indicate a maturing research focus on blockchain applications in specific managerial sectors, such as finance and supply chain management. However, this field's conceptual evolution is posited to be in its infancy in other sectors, such as for managing luxury goods and counterfeit products. Further, the thematic classification of the extant literature led to the identification of the following four major themes of research: strategy and regulation, enablement and implication, multi-domain deployment, and the inefficiencies of bitcoin. These findings are used to propose directions for further research in this field, such as the need for methodological advancement and theoretical grounding.

Purpose Blockchain is one of the most significant emerging technologies that is set to transform many aspects of industry and society. However, it has several major technical, social, legal, environmental and ethical complexities that offer significant challenges for mainstream use within the public sector. The coronavirus disease 2019 (COVID-19) pandemic has compelled many public sector employees to work remotely, highlighting a number of challenges to blockchain adoption within the Indian context signifying the pertinence of this research topic in the post-pandemic era. This study offers insight to researchers and policymakers alike on how such challenges are interdependent within this important subject. Design/methodology/approach We explored 16 unique sets of challenges selected from the literature and gathered data from nine experts from government settings, healthcare and education sectors and academia who have significant knowledge and experience of blockchain implementation and use in their respective organisations. The implementation of Interpretive Structural Modelling (ISM) and Matriced' Impacts Croise's Multiplication Appliquée a UN Classement (MICMAC) provided a precise set of driving, linkage and dependent challenges that were used to formulate the framework. Findings The developed ISM framework is split into six different levels. The results suggest that the bottom level consists of challenges such as “Lack of standards (C9)” and “Lack of validation (C10)” form the foundation of the hierarchical structure of blockchain adoption. However, the topmost level consists of a highly dependent challenge termed “adoption of blockchain in the public sector (C16)”. The research filters the selected set of five challenges to develop a parsimonious model and formulated six propositions to examine the impact of “lack of standard (C9)”, “lack of validation (C10)” on “security issues (C3)” and “privacy concerns (C2)”, which eventually determine individuals' “reluctance to use blockchain technology (C12)”. Originality/value This research fills a key gap in exiting research by exploring the key challenges in blockchain adoption within the public sector by developing a valuable framework to model this important topic. To the best of our knowledge, this is the first paper to address these challenges and develop a parsimonious model for challenges of blockchain adoption in the public sector settings.

Planning to adopt the Blockchain is very active in many industries, especially in supply chains. Researchers believe that the Radio-frequency identification (RFIDs), yesterday’s Blockchain, is now obsolete. The strongest reason that the Blockchain is the tool of this era is its unique features; real-time information sharing, cyber-security, transparency, reliability, traceability, and visibility, all of which boost the supply-chain performance. Despite the extensive literature on Blockchain, in recent years, no clear framework has defined whether a supply chain should implement Blockchain or not. This study attempts to fill this gap by proposing a framework for complex supply chain networks. In doing so, first, we identified the supply-chain practices of the oil industry in Pakistan, then we empirically analyzed the impact of these practices on operational performance. The results show that the supply chain management (SCM) practices positively impact operational performance. On the other hand, with the help of literature, we identified different Blockchain features and their influence on different supply chain practices. This study guides managers and decision-makers to evaluate their current supply-chain practices and understand the relationship between supply-chain practices and Blockchain features, and how different Blockchain features can help improving supply-chain practices and ultimately improving operational performance.

The conventional education system in developing countries has been enhanced recently by implementing the latest technology of distributed ledger. Disruptive technology is a fundamental requirement for greater accountability and visibility. We explored the key factors affecting the intentions of educational institutions to use blockchain technology for e-learning. This study proposed an expanded model of Technology Acceptance Model by integrating the diffusion of innovation theory. Based on an online survey, the conceptual model was tested and validated using structural equation modeling. The results showed that compatibility had a significant impact on blockchain use in smart learning environments. Other significant effects were also found on adoption of blockchain technology. This study offers an expanded Technology Acceptance Model for implementing blockchain that could assist decision makers in building a smart learning environment for the educational institutes for the emerging economies.
Abstract Service supply chain management is a complex process because of its intangibility, high diversity of services, trustless settings, and uncertain conditions. However, the traditional evaluating models mostly consider the historical performance data and fail to predict and diagnose the problems’ root. This paper proposes a distributed, trustworthy, tamper-proof, and learning framework for evaluating service supply chain performance based on blockchain and adaptive network-based fuzzy inference systems (ANFIS) techniques, named Di-ANFIS. The main objectives of this research are as follows: (1) presenting hierarchical criteria of service supply chain performance to cope with the diagnosis of the problems’ root; (2) proposing a smart learning model to deal with the uncertainty conditions by a combination of neural network and fuzzy logic; and (3) introducing a distributed blockchain-based framework due to the dependence of ANFIS on big data and the lack of trust and security in the supply chain. Furthermore, the proposed six-layer conceptual framework consists of the data layer, connection layer, blockchain layer, smart layer, ANFIS layer, and application layer. This architecture creates a performance management system using the Internet of Things, smart contracts, and ANFIS based on the blockchain platform. The Di-ANFIS model provides a performance evaluation system without needing a third party and a reliable intermediary that provides an agile and diagnostic model in a smart and learning process. It also saves computing time and speeds up information flow.
Applying blockchain technology for information sharing in supply chain is driven by many factors, but developing trust is one of the most proposed. However, trust is a multidimensional, intangible concept without an agreed-upon definition. Whereas some argue that trust is the main driver of blockchain technology, others have found a negative relationship. This study focuses on how applying blockchain in supply chain management can influence trust and proposes a corresponding research agenda. Trust and blockchain technology discussions are scattered throughout the literature. Thus, a systematic literature review was performed based on a conceptual trust framework. This study discovered a gap in linking trust theories to blockchain technology applications especially in supply chain management, and provided insights into trust's reciprocal nature. Current literature strongly expects trust as a consequence for blockchain adoption if considered in the technology. Simultaneously, trust in supply chain partners is strongly expected as an antecedent to blockchain because it requires openness in information sharing. Thus, propositions and agenda for future research are suggested. The research is limited to literature findings due to the immaturity and low scalability of blockchain technology adoption; however, the most reviewed articles in less than two years old, increase the results' accuracy.
Blockchain technology has been gaining traction across different sectors. It has the potential to immensely benefit the healthcare sector, given the sector's inherent complexities, problems, and inefficiencies. However, to date, no comprehensive, evidence-based effort has been made to understand the readiness of this sector for blockchain adoption. We proposed a readiness assessment framework that encompasses the complex interplay of different underlying factors, social structures, and institutional mechanisms and that covers all key stakeholders. Based on a systematic literature review, the framework is applied to the UAE's healthcare sector and its applicability and usefulness is established. The findings show the multifaceted significance of government readiness in driving blockchain initiatives. Large firms are found to be more willing to leverage the opportunities afforded by blockchain. Lack of clarity on blockchain regulations and laws, and issues pertaining to privacy and trust are found to affect the readiness of all stakeholders. The proposed framework and the study's findings will be useful in guiding policy interventions and developing support mechanisms to strengthen areas related to blockchain adoption.

After the development and inception of cryptocurrencies, Blockchain has found much usefulness in many domains. The Blockchain technology offers several advantages like decentralization, traceability, anonymity, cryptography, collective maintenance and immutability. The possible disruption and prospective capabilities of the Blockchain technology has been extensively utilized in the Finance domain. There has been extensive exploration on the integration and application of Blockchain technology in the domain of supply chain and supply chain finance as well. But, a detail framework of application is seldom mentioned. In this research, we have studied and analyzed the possible synchronization between Blockchain technology and supply chain finance. This study also presents a conceptual framework based on Blockchain technology to enhance the efficiency of supply chain financing for small and medium scale enterprises. Finally, this study proposes three supply chain finance models and their operation processes on a Blockchain Platform.
