Blockchain has gained momentum as a disruptive technology in supply chain management against its introduction as a finance-related instrument. Nevertheless, the developing academic understanding and the limited practical implications lead to insufficient insights into the use of blockchain technology, particularly in the supply chain finance (SCF) domain. Thus, the expected potential of blockchain technology remains underexplored. Accordingly, this study explicates this situation by examining the extant literature findings and web-based big data that can provide evidence about the real needs in supply chains, and investigating how blockchain emerges as a disruptive SCF-oriented technology. The study employs a web analytics method, Search Engine Results Page (SERP) analysis which considers the trends in blockchain technology use and the interactions between blockchain, supply chain and finance appearing in Google searches. The SERP method examined real-time clicks, web traffics and most commonly asked questions about blockchain. The SERP findings revealed that the interest in blockchain technology neither focused on finance nor data privacy as emphasised in the literature but mainly on the benefits of increasing digitalisation and efficiency in supply chains. The results offered practical implications for capturing recent blockchain- and supply chain-related trends and designing more digital and efficient supply chains.

Supply chains face many challenges around coordination, information asymmetry, quality assurance, complex disruptions, and traceability. Blockchain is arguably a technology that can address these challenges and make a significant impact. To shed light on the impact of blockchain, we undertake a cross-discipline systematic literature review on blockchain and supply chains. This review focused on identifying blockchain’s current and proposed impacts on the supply chain at three levels: organisational, inter-organisational, and industry. The findings identified twelve core supply chain themes across pre-implementation, post-implementation, and emerging tensions associated with adopting blockchain. These findings extend knowledge by going beyond understanding blockchain and its application and articulating multi-levels of impacts. Based on our review, we propose future research directions. By providing an overview of the current impact of blockchain, the review also offers insights to help managers to make informed decisions around the implementation and use of blockchain in supply chains.

This study investigates the variables affecting the adoption of blockchain technology (BT) among small and medium-sized enterprises (SMEs) with the application of artificial intelligence (AI) via the mediating lens of risk-taking behavior. As an initial sample, 150 owners/top managers from 150 SMEs (one informant from each) in Dhaka, Bangladesh, were chosen. A stratified random sample was employed for this cross-sectional study. Applying structural equation modeling, the combined influence of internal and external variables influencing the intention to adopt BT is explored. Results show that: (1) knowledge of artificial intelligence has a positive and significant effect on the adoption of blockchain technology; (2) the relevant advantage of artificial intelligence has a positive and significant effect on the adoption of blockchain technology; (3) perceived ease of use of artificial intelligence has a positive and significant effect on the adoption of blockchain technology; (4) risk-taking behavior mediates the relationship between knowledge of artificial intelligence and adoption of blockchain technology; (5) risk-taking behavior does not mediate the relationship between relevant advantage and perceived ease of use of artificial intelligence with the adoption of blockchain technology. The current study is one of the few empirical investigations relating to SMEs using artificial intelligence and blockchain technologies for business operations. The study’s limitations are the small sample size and use of a single informant. However, the findings on the adoption of blockchain technology have applications for boosting the competitiveness of SMEs. This study’s originality stems from two factors: the novelty of blockchain technology and its potential to upend SMEs’ conventional mode of operation. It highlights the need to consider the key variables affecting SMEs’ adoption of blockchain technology with artificial intelligence.
Dating back many millennia, agriculture is an ancient practice in the evolution of civilization. It was developed when humans thought about it and concluded that not everyone in the community was required to produce food. Instead, specialized labor, tools, and techniques could help people achieve surplus food for their community. Since then, agriculture has continuously evolved across the ages and has occupied a vital, synergistic position in the existence of humanity. The evolution of agriculture was based on a compulsion to feed the growing population, and, importantly, maintain the quality and traceability of food, prevent counterfeit products, and modernize and optimize yield. Recent trends and advancements in blockchain technology have some significant attributes that are ideal for agriculture. The invention and implementation of blockchain have caused a fair share of positive disruptions and evolutionary adoption in agriculture to modernize the domain. Blockchain has been adopted at various stages of the agriculture lifecycle for improved evolution. This work presents an intense survey of the literature on how blockchain has positively impacted and continues to influence various market verticals in agriculture, the challenges and the future.

Electronic Health monitoring system has performed an essential role in managing healthcare monitoring. E-health can provide effective and valuable facilities for the patients to monitor. Though, there are protection disputes in the current E-Health system. The current e-health system, on the other hand, has security issues. Malevolent doctors may work together with cloud Storage Service Providers (CSPs) to interfere with patients' electronic health records (EHRs) or promptly leak EHR matter to other enemies for income. (EHRs). The malevolent doctors may conspire with the Patient Healthcare Monitoring Service Provider (PHMSP) to manipulate with the patients'. For profit, EHRs or directly divulge the EHR content of EHRs to other opponents. Block-chain has recently appeared as one of the most powerful methods in the protection and secrecy fields. It is assumed to be the promised security approach that will eventually replace the security challenges in existing e-health monitoring systems. Encryption in blockchain refers to technical methods that make accessing encrypted data difficult for unauthorized resources. This research proposed a blockchain-based encryption framework to provide security-based solutions using a computational intelligence methodology.

The emerging Web3 economy and the Blockchain's massive adoption in 2021 shape the industry's future driven by distributed ledgers and smart contracts. Blockchain technology enables traceability, fraud prevention, and faster settlement of business processes, including talent recruitment. The current recruitment requires Applicant Tracking System (ATS), Artificial Intelligence (AI), and third-party HR recruitment agencies for sorting and verifying job application documents in every recruitment cycle, which are ineffective and inefficient. This paper proposes a model to discover and recruit reputable talent by leveraging blockchain technology, which enables trustless networks and allows entities to conduct transactions without mutual trust, called the recruitment system. This paper also seeks to enhance the relationship among recruitment entities by adopting a transparent and incorruptible decentralized autonomous organization (DAO) model powered by blockchain technology.

Abstract Organizations adopt blockchain technologies to provide solutions that deliver transparency, traceability, trust, and security to their stakeholders. In a novel contribution to the literature, this study adopts the technology-organization-environment (TOE) framework to examine the technological, organizational, and environmental dimensions for adopting blockchain technology in supply chains. This represents a departure from prior studies which have adopted the technology acceptance model (TAM), technology readiness index (TRI), theory of planned behavior (TPB), united theory of acceptance and use of technology (UTAUT) models. Data was collected through a survey of 525 supply chain management professionals in India. The research model was tested using structural equation modeling. The results show that all the eleven TOE constructs, including relative advantage, trust, compatibility, security, firm’s IT resources, higher authority support, firm size, monetary resources, rivalry pressure, business partner pressure, and regulatory pressure, had a significant influence on the decision of blockchain technology adoption in Indian supply chains. The findings of this study reveal that the role of blockchain technology adoption in supply chains may significantly improve firm performance improving transparency, trust and security for stakeholders within the supply chain. Further, this research framework contributes to the theoretical advancement of the existing body of knowledge in blockchain technology adoption studies.
Currently, the emerging countries like Morocco seeks to benefit from the potential of blockchain technology to meet its various growing demands, especially in sustainable supply chain management (SSCM). This explains the need for more effort to understand blockchain implementation and identify the barriers influencing the blockchain adoption decision in SSCM, especially, from Moroccan industry and service sectors perspective. In this context, this research paper proposes a group decision-making approach to identify the barriers from a comprehensive literature search, then evaluate them based on intuitionistic fuzzy analytic hierarchy process (IFAHP). Due to the varied importance of the selected barriers, IFAHP is utilized to allocate priority weights for each barrier according to its importance level. The evaluation results reveal that “Government policy and support” and “Challenges in integrating sustainable practices and blockchain technology through sustainable supply chain management (SCM)” are the best ranked barriers that impact the implementation of blockchain technology in Moroccan context. The main objective is to inquire the barriers preventing the blockchain implementation, and assist industry decision-makers in developing supple short- and long-term decision-making strategies for better sustainable supply chain management.
Aiming at improving the enterprise performance and venture capital management, the edge computing is combined with blockchain technology in the construction of the supply chains so as to improve the stability and security of raw material supply chains of venture capital enterprises. Firstly, the relationships among venture capital, enterprise performance, and supply chain integration are analyzed, and the positive impacts of optimization and innovation of supply chain technology and venture capital on enterprise performance improvement are discussed. Secondly, the edge computing and blockchain technology are adopted to optimize the supply chain, and a protocol model is established to improve the security of supply chain information transmission. In addition, the supply chain Internet of Things (IoT) system is designed in layers based on blockchain and edge computing technology. Finally, the designed protocol model is applied to the supply chain and the supplier performance is evaluated by using the fuzzy analytic hierarchy process (FAHP). The results show that the gas value of the designed protocol model is stable at 104,000∼116,000 in blockchain transactions, and the execution time of a single blockchain transaction fluctuates between 4,300 and 6,100 ms. Therefore, the designed protocol model can effectively ensure the security of supply chain data during the transmission. The evaluation results of supplier performance suggest that the cooperative relationship between venture capital enterprises and suppliers is affected by many factors. Optimizing the supply chain structure and production activities can improve the performance of suppliers and venture capital enterprises. This work provides a reference for analyzing the performance of blockchain technology on venture capital enterprises and suppliers.

However, challenges such as high initial investments, scalability issues, and the need for industry-wide standards were identified as barriers to widespread adoption. The study emphasized the importance of continued research to address these challenges and refine blockchain applications in supply chain management. Unique Contribution to Theory, Practice and Policy: The Theory of Transaction Cost Economics, Resource-Based View (RBV) of the Firm and Agency Theory may be used to anchor future studies on blockchain technology in supply chain management. The study recommended expanding theoretical frameworks to better incorporate blockchain technology's unique aspects into supply chain theories. Practically, organizations were advised to conduct pilot projects and phased rollouts to evaluate blockchain's impact before large-scale implementation, and to invest in training for effective technology management. Policy recommendations included the development of regulatory frameworks and industry standards to facilitate blockchain adoption. Collaboration among industry stakeholders was encouraged to address integration challenges and standardize solutions. Further research into specific applications and the integration of blockchain with other technologies was suggested, alongside investment in education and training programs for supply chain professionals.
Today, smart supply chains are one of the main and growing applications of evolving technologies such as the Internet of Things (IoT), artificial intelligence (AI), and blockchain, which bring many benefits. IoT and blockchain security is a subset of cybersecurity that protects against IoT-related threats. Therefore, the simultaneous combination of these technologies and the creation of a supply chain based on the artificial intelligence of things (AIoT) and blockchain, in addition to increasing the performance of activities in supply chain processes, can also bring many security challenges to this smart supply chain. Because the data collected by IoT devices and stored in the blockchain-based systems that manage them are much more sensitive than traditional network security strategies.Due to the importance of this issue, in this study, an attempt has been made to analyse these security indicators in the AIoT and blockchain-based intelligent supply chain using a combined decision-making method in a fuzzy neutrosophic environment. Understanding these security measures will definitely help to implement more secure and powerful smart supply chains. The results showed that customer privacy criteria have the highest priority. The following priorities are authentication, Security challenges based on infrastructure, and network integrity.

In Industry 4.0, the development of intelligent supply chains is the key to improving enterprise efficiency and customer satisfaction. At present, the strategy with blockchain to optimize the supply chain ensures the security of data sharing and interaction between different suppliers. However, the quality of service (QoS) loss in time efficiency and supplier cooperation is still a severe problem in these strategies. Therefore, it is essential to conduct reputable supplier selection to reduce QoS loss under the premise of blockchain security. Meanwhile, choosing a reputable supplier as the primary peer in the blockchain consensus process can also effectively reduce transaction latency. To solve this problem, a reputation-aware supplier assessment system, named SAS, is proposed. Specifically, Canopy and K-medoids are utilized to classify suppliers preliminarily. Then backpropagation neural network is deployed to evaluate supplier reputation. The results show that SAS is effective in supplier reputation evaluation through extensive experiments.
