【Abstract】Blockchain technology use cases for supply chains-strategically and operationally-have been highlighted in practice and in research. In this respect, various applications of analytical models have been introduced to un-derstand, analyze and make decisions related to blockchain phenomenon in production, operations, and supply chains. This work has received extensive-and some would argue unprecedentedly-rapid attention within the scholarly community. This early growth sets the stage for large-scale academic research and commercialization. Acknowledging this level of popularity, we provide a critical review of analytical models analyzing the current state-of-the-art research. This includes a synthesis of works that classify different research areas and general analytical model application within each research area. Bibliometric and network analysis tools help identify critical research contributions, key research areas, relationships among analytical models and research areas. Major findings include: (1) analytical models in this field are expanding rapidly; (2) the International Journal of Production Economics has been central to the analytical and production economic modeling research discourse; (3) ten research areas including antecedents, actions, scenarios and consequences are identified from a network analysis; and (4) the relationship between analytical models and research areas is evolving with insight into why and in which direction this work is likely to continue. We identify significant research gaps with great potential for scholarly advancement.

【Abstract】Vaccination offers health, economic, and social benefits. However, three major issues-vaccine quality, demand forecasting, and trust among stakeholders-persist in the vaccine supply chain (VSC), leading to inefficiencies. The COVID-19 pandemic has exacerbated weaknesses in the VSC, while presenting opportunities to apply digital technologies to manage it. For the first time, this study establishes an intelligent VSC management system that provides decision support for VSC management during the COVID-19 pandemic. The system combines block -chain, internet of things (IoT), and machine learning that effectively address the three issues in the VSC. The transparency of blockchain ensures trust among stakeholders. The real-time monitoring of vaccine status by the IoT ensures vaccine quality. Machine learning predicts vaccine demand and conducts sentiment analysis on vaccine reviews to help companies improve vaccine quality. The present study also reveals the implications for the management of supply chains, businesses, and government.

【Abstract】Shared manufacturing (SM) is an advanced manufacturing mode to solve the problems of information asymmetry and resource imbalance in the complex supply and demand relationship under the background of mass personalization. Blockchain can provide technical solutions for trust issues between manufacturing service providers and demanders, but less research has focused on the stable maintenance of a blockchained shared manufacturing network (BSMN). Industrial knowledge graph and cognitive intelligence play an important role in designing incentive mechanisms for BSMN. Based on the evolutionary game theory, this paper designs various incentive models and develops the corresponding smart contracts to encourage different enterprises to partici-pate in the "accounting" operations, to enhance the trust and maintain the operational stability of BSMN. Firstly, the evolution mechanism of BSMN was analyzed. Then, an evolutionary game model between shared manufacturing enterprise nodes was established to deduce the stable state of BSMN. Based on the analysis of the evolutionarily stable state, an incentive model with three strategies to encourage different enterprise nodes to participate in "accounting" operations was determined, and smart contracts of the incentive models were developed. Finally, the effectiveness of the proposed incentive models was verified by simulation experiments.

【Abstract】With the continuous development of Internet of Things, finance, big data and many other fields, blockchain has been widely used in these areas for transactions, data sharing, product traceabil-ity and so on. Numerous assets have appeared in the blockchain, and there are some levels of conflicts among privacy protection of these assets, transaction transparency and auditability in blockchain; so how to provide privacy preserving, make public verifications and audit the encrypted assets are chal-lenging problems. In this paper, we propose a privacy-preserving transaction scheme with public ver-ification and reliable audit in blockchain. First, we provide privacy preserving of transaction contents based on homomorphic encryption. It is flexible, as we decouple user identity and transaction contents. Then, we propose and design a multiplicative zero-knowledge proof with formal security analysis. Fur-thermore, several verification rules are defined by us in the scheme, such as balance verification and multiplicative verification based on the proposed multiplicative zero-knowledge proof. Our scheme enables reliable and offline auditing for each transaction, and we aggregate the zero-knowledge proofs to save the ledger space. Finally, we make a security analysis of our proposal in terms of transac-tion confidentiality, public verification and audit reliability, and we give a performance analysis of the proposed scheme.

【Abstract】The Internet of Medical Things (IoMT) significantly impacts our healthcare system be-cause it allows us to track and verify patient medical data before storing it in the cloud for future use. A rapidly expanding platform like IoMT requires high security to keep all data safe. The pa-tient's prescription history and other sensitive information must be encrypted and managed with great care. Nevertheless, it is challenging to determine what data uses are acceptable while protecting pa-tient privacy and security. Understanding the limits of current technologies and envisioning future research paths is crucial for establishing a safe and reliable data environment. An untrustworthy per-son can communicate with a trustworthy person via blockchain, a decentralized digital ledger that allows for end-to-end communication. Therefore, this research suggests that the healthcare industry with blockchain-integrated cyber-security based on artificial intelligence (BICS-AI) in medical care to preserve medical-related things. Blockchain applications have the potential to consistently identify the most severe, potentially life-threatening mistakes in the medical field. The use of blockchain for decentralized data protection helps to protect patient health records from compromise. With the help of an access control provider (ACP), here came up with a lightweight solution that addresses this issue by allowing the delegating of security operations. Medical data from IoMT and integrated devices can be collected and stored securely and distributed using a conventional in-depth approach combined with blockchain, making it suitable for healthcare professionals such as nursing homes, hospitals, and the healthcare industry where data exchange is required. The research findings indicate that the suggested system is viable and has a 94.84% security rate, a security performance of 96.4%, a success rate of 89.9%, and a 5.1% latency rate compared to traditional methods.

【Abstract】The advent of telemedicine with its remote surgical procedures has effectively transformed the working of healthcare professionals. The evolution of telemedicine facilitates the remote monitoring of patients that lead to the advent of telesurgery systems, i.e. one of the most critical applications in telemedicine systems. Apart from gaining popularity, the telesurgery system may encounter security and trust issues of patients' data while communicating with the surgeon for their remote treatment. Motivated by this, we have presented a comprehensive survey on secure telesurgery systems comprising healthcare, surgical robots, traditional telesurgery systems, and the role of artificial intelligence to deal with the numerous security attacks associated with the patients' health data. Furthermore, we propose a blockchain and federated learning-based secure telesurgery system to secure the communication between patient and surgeon. The results of the proposed system are better than those of the traditional system in terms of improved latency, low data storage cost, and enhanced data offloading. Finally, we explore the research challenges and issues associated with the telesurgery system.

区块链应用-虚拟经济-ICO

【Abstract】Recent research finds that whether or not ventures publish video pitches during crowdfunding campaigns affects their funding success. Little is known, however, about how and why video pitches help startups achieve higher valuations. To close this gap, we analyze metrics and the content of video pitches published along blockchain-based crowdfunding campaigns (a.k.a. token offerings, initial coin offerings, or ICOs). We confirm that the publication of video pitches increases the funding amount, and present novel evidence on the mechanisms behind this finding. First, the longer the video, the larger its valuation effect. Second, it is the information content that matters in videos, while non-informational content (e.g., music) has no effect. Third, information conveyed in videos vis-`a-vis other channels (e.g., white papers) act as informational substitutes. Fourth, investors react positively to buzz words in videos, and this effect is even more pronounced when there are many competing projects. Overall, our results suggest that videos are an important source of information for ICO investors, and investors' limited attention makes videos (and their content, especially buzzwords) more important in "hot" markets.

【Abstract】The article is devoted to the key issues that arise when digital objects are included in the heritage. The author consider how the classical theory of inheritance law can be used in the case of digital inheritance and what clarifications should be made to this theory. The purpose of the research is to examine the features of the category "objects of hereditary succession" and its transformation in the case of the digital transformation in society. In order to achieve this purpose the author in the first part of the research studies the general issues of the theory of objects of inheritance. The second part of the article it is analyzed the problems of attributing some objects of civil legal relations that have arisen in the process of digitalization of society to the hereditary mass (digital rights, cryptocurrency, social nets accounts). Finally, in the third part, using inductive reasoning, the researcher formulates general conceptual problems of the development of legislation related to digital objects of inheritance. Based on the results of the research, it was concluded that the following legislative solutions to the identified problems are possible: the establishment of a complete ban on inheritance of digital assets; the creation of a separate legal regulation of inheritance relations specifically for digital assets; the assumption of the fact of inclusion in the hereditary mass of a digital object only if it is really possible to put it into circulation; the assumption of some features of inheritance of "digital objects". Undoubtedly, the choice of approach strongly depends on the state's policy in the field of the digital economy, which in turn should proceed from sound concepts and practical proposals. The position of the author of the article is that the legal regulation of "digital" hereditary relations in Russia has be based on a mixed method, including a combination of traditional and technological methods. Such a method is most correlated with the assumption of the fact of inclusion in the hereditary mass of a digital object only if it is really possible to put it into circulation.
