【Abstract】The number of Electric Vehicles (EVs) on the road has steadily grown in the past decade in response to an urgent call to reduce carbon emissions. This growth must be accompanied by robust charging solutions to relieve range anxiety in EV drivers, especially in long-haul routes with little to no infrastructural support outside of cities. Mobile Charging Stations (MCS) deployed on trucks are becoming a popular solution in such scenarios. However, incorporating MCS in the EV energy trade market faces three main challenges: (1) an efficient allocation of MCS, (2) ensuring truthfulness in energy price bidding to avoid price inflation, and 3) ensuring secure, transparent transactions without compromising the security of the participants. To tackle these problems, a zone-distributed auction framework is proposed that can be deployed on smart contracts, providing a well-rounded solution for EV owners to avail energy from a fleet of MCS. In this work, a Repeated Single- Minded Auction (R-SMB) model is used, where the MCS bid to earn the right to serve charging requests received in their proximity. With each round of allocation, the approach allows for path planning of the deployed MCS while also controlling foul play with the energy prices in the local market through the competition incorporated by the auctions. Furthermore, the smart contract implementation of the framework ensures a trusted and transparent execution of the auction, MCS allocation as well as payment completion. The performance of the proposed framework is evaluated against the optimal Vickrey-Clarke-Grove (VCG) auction to prove its viability.

【Abstract】The Life Cycle Sustainability Assessment (LCSA) methodology offers a promising solution to achieve a sustainable built environment by simultaneously considering all sustainability pillars. However, traditional LCSA applications are typically confined to the early design stages of building projects, where they assess the entire life cycle of a building using static historical data rather than being employed as a decision-making tool throughout all project phases with real-time data integration. This research addresses these limitations by investigating the integration of LCSA with Digital Twin (DT) and Blockchain technologies to enhance sustainability assessments in building projects. The primary aim is to develop a dynamic framework that incorporates realtime data across a building's entire life cycle. This study utilizes a systematic literature review to identify current trends and gaps, leading to the development of an integrative framework validated through a case study of a typical residential building. The findings demonstrate that integrating DT facilitates continuous monitoring and assessment of environmental, economic, and social impacts, while Blockchain ensures data security, integrity, and transparency. This novel approach supports real-time, iterative LCSA applications, enhancing decision-making from design through construction and maintenance. By showcasing a practical application of DT and Blockchain in real-world scenarios, this framework significantly advances sustainable practices in construction. The originality of this research lies in its holistic approach, combining DT and Blockchain to deliver a more accurate, reliable, and comprehensive sustainability assessment model, setting a new standard for future developments in the field.

【Abstract】Enhancing data privacy security in medical data sharing is crucial for the informatization development in the healthcare sector. This paper proposes a healthcare data sharing scheme based on two-dimensional chaotic mapping and blockchain (2DCM-DS). Specifically, a new two-dimensional chaotic mapping is proposed, which demonstrates superior chaotic performance. Then, by incorporating biometric audio information as an identity credential and integrating it with the proposed two-dimensional chaotic mapping, we design a data encryption method that establishes a strongly coupled and bi-directionally verifiable data ownership relationship in healthcare data sharing. Finally, we employ blockchain as the underlying network and design corresponding smart contracts to support 2DCM-DS. This approach addresses potential issues of unauthorized access, malicious tampering, and single points of failure in centralized data sharing. Experimental results demonstrate that 2DCM-DS effectively protects data security under the specified attack models. The results validate the security and efficiency of the 2DCM-DS, proving its application potential in healthcare insurance data sharing scenarios.

【Abstract】The expansion of smart contracts on the Ethereum blockchain has created a diverse ecosystem of decentralized applications. This growth, however, poses challenges in classifying and securing these contracts. Existing research often separately addresses either classification or vulnerability detection, without a comprehensive analysis of how contract types are related to security risks. Our study addresses this gap by developing a taxonomy of smart contracts and examining the potential vulnerabilities associated with each category. We use the Latent Dirichlet Allocation (LDA) model to analyze a dataset of over 100,040 Ethereum smart contracts, which is notably larger than those used in previous studies. Our analysis categorizes these contracts into eleven groups, with five primary categories: Notary, Token, Game, Financial, and Blockchain interaction. This categorization sheds light on the various functions and applications of smart contracts in today's blockchain environment. In response to the growing need for better security in smart contract development, we also investigate the link between these categories and common vulnerabilities. Our results identify specific vulnerabilities associated with different contract types, providing valuable insights for developers and auditors. This relationship between contract categories and vulnerabilities is a new contribution to the field, as it has not been thoroughly explored in previous research. Our findings offer a detailed taxonomy of smart contracts and practical recommendations for enhancing security. By understanding how contract categories correlate with vulnerabilities, developers can implement more effective security measures, and auditors can better prioritize their reviews. This study advances both academic knowledge of smart contracts and practical strategies for securing decentralized applications on the Ethereum platform.

【Abstract】Small and medium enterprises (SMEs) in supply chains often struggle to obtain external financial resources from banks, due to their poor supply chain visibility. Prior studies suggest that adopting blockchain technology can enhance supply chain visibility, thus facilitating access to supply chain finance (SCF). In this study, we compare the traditional SCF mode with the blockchain-enabled SCF mode within the framework of a dual-channel closed-loop supply chain (CLSC). Our analysis incorporates both prepayment financing and accounts receivable financing or purchase order financing into the analytical model. Our main findings are as follows. Firstly, adopting blockchain technology leads to a reduction in the interest rate, enabling the manufacturer and the retailer to raise their buy-back prices. This increase in buy-back prices subsequently encourages greater recycling of used products. Secondly, in a context marked by high cross-price elasticity, we observe abrupt pricing fluctuations in both online and offline sales channels. However, adopting blockchain technology can effectively mitigates these fluctuations, thus ensuring the sustained stability of demand in both sales channels. Thirdly, in the blockchain-enabled mode, equilibrium wholesale price, offline sales price, manufacturer's buy-back price, and retailer's buy-back price are higher compared to those in the traditional mode. Conversely, the equilibrium direct sales price is lower in the blockchain-enabled mode than in the traditional mode. Fourthly, changes in interest rates and cross-price elasticity have analogous impacts on pricing dynamics in both the traditional and blockchain-enabled modes. Fifthly, adopting blockchain technology leads to an all-win outcome for participants in SCF arrangements only when the benefits of blockchain-enabled traceability and reduced interest rates outweigh the costs associated with hosting and access.

【Abstract】The scalability challenge in consensus methods based on Proof of Work (POW) has led to the popularity of voting-based consensus methods. Practical Byzantine Fault Tolerance (PBFT) is one of the most desired approaches. However, the PBFT protocol faces communication complexity and possible faulty behaviors of nodes that can disrupt the consensus process. To reduce the complexity of PBFT, sharding is a useful technique. However, sharding may decrease the probability of successful consensus in PBFT, as the effects of faulty nodes become more destructive. In this paper, we introduce a shard-based Dynamic Balanced Consensus Tree (DBCT) that is well-suited for performing PBFT hierarchically. Additionally, we propose a distributed configuration method that gradually develops this structure while the PBFT consensus is in progress. Proper distribution of node weights in Sharding committees can provide a basis to propose appropriate ideas for aggregating votes in PBFT, control node clustering based on weight parameters, and provide a fair and proportional method to select the block-proposer node. Furthermore, the unpredictable dynamic configuration of this consensus structure could be considered as a defense strategy against some possible attacks. The simulation results confirm the quality of our proposed configuration method to make a dynamic and balanced consensus tree while the consensus is in progress. Our numerical analysis results confirm the capability of the proposed consensus structure and its distributed configuration method in efficiently balancing node placement across the layers of the dynamic consensus structure.

【Abstract】The Internet of Things (IoT) has expanded rapidly, generating vast amounts of data that require effective protection. Traditionally, the attribute-based searchable encryption (ABSE) as been used within IoT to maintain data privacy and integrity. However, existing ABSE approaches often rely on centralized systems that are susceptible to single-point failures and are inefficient in terms of decryption and data retrieval. Therefore, we propose a novel blockchain-assisted multi-keyword searchable encryption scheme (BAMKSE) that utilizes the decentralized nature of blockchain to overcome these limitations. This scheme integrates ciphertext policy attribute-based encryption (CP-ABE) with key policy attribute-based encryption (KP-ABE) to provide advanced access control and mutual authentication, while offloading the computational burden of decryption to cloud-based pre-decryption services. Security analyses demonstrate the resilience of BAMKSE against chosen keywords attacks (CKAs) and chosen-plaintext attacks (CPAs), offering an effective solution for secure and efficient IoT data handling.

【Abstract】Blockchain technology is rapidly transforming how businesses and individuals interact. Its inherent security features, including immutability, tamper-proofing, and verifiable data provenance, are driving its adoption across numerous sectors. The financial sector heavily influences blockchain for its tamper-proof nature, leading to the rise of cryptocurrencies, the technology offers much more. Beyond security, it streamlines processes, reduces costs, and improves customer experience. Smart contracts are one of the predominant key components that automate predetermined operations, further enhancing blockchain's capabilities. Understanding the importance of blockchain in non-financial applications is crucial for fully exploiting its potential. This analysis explores the fundamentals of blockchain technology and its applications beyond finance. To meet the growing demand across various sectors, blockchain must integrate with other trending technologies such as the Internet of Things (IoT), Artificial Intelligence (AI), and the edge-cloud paradigm. The analysis examines the role of these technologies in facilitating blockchain-enabled applications. Furthermore, the paper researches the specific use cases such as insurance, energy, healthcare, digital voting, supply chain management and government. Concentrating on these sectors elucidates how organisations harness blockchain to tackle intricate challenges, thereby fostering the advancement of sophisticated digital processes and contributing to societal progression.

【Abstract】Purpose: This paper aims to analyze the connectedness between the natural gas, wheat, gold, Bitcoin and Gulf Cooperation Council (GCC) stock indices with the advent of exogenous and unexpected shocks related to the health and political crises. Design/methodology/approach: For this end, a quantile-based connectedness method is applied on returns of different assets during the period 01/01/2016-05/01/2024. Findings: The empirical findings display that the existence of time-varying connectedness between markets is well-documented and seems to be stronger during the COVID-19 pandemic and the Russia-Ukraine war. The connectedness is fostered with extreme events, showing that shocks propagate increasingly during turbulent periods compared with calm ones. The connectedness is event-dependent. Practical implications: The empirical results offer insightful information for policymakers and investors about the contagion effect and volatility spillover among GCC stock markets and other asset classes during different crises. Originality/value: This study examines different asset classes' dynamism connection with sock prices in the GCC countries to better apprehend the (dis)similarities between different asset classes in terms of information transmission. It also investigates the connectedness structure among different asset classes under extreme market conditions and how spillover effects across GCC markets and other ones can be time- and event-dependent.

【Abstract】Due to the scarcity of spectrum and the abuse of idle spectrum, it is very important to share idle spectrum to achieve greater utilization of spectrum. Unfortunately, the existing research hardly considers the security problem and privacy protection of spectrum trading in the dynamic spectrum sharing (DSS) system. Thus, we propose a secure and conditional privacy-preserving blockchain-based spectrum trading scheme in a DSS system. We exploit blockchain and ring signature to build a spectrum sharing system to solve the spectrum access and management issues. In our scheme, primarily, Monero currency is used to trade the spectrum between users for ensuring the fairness of the transaction. Besides, the ring signature on blockchain can realize all legal users' anonymity during the spectrum trading. Furthermore, we design an ID-based traceable ring signature to achieve conditional anonymity, which can avoid malicious users from disturbing normal transactions. The security analysis shows that our scheme can realize users' conditional anonymity, unforgeability, and transactions' traceability. The performance evaluation demonstrates that the computational overhead of our scheme in the signature, verification and tracing process does not exceed 15%\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$15\%$$\end{document}, 60%\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$60\%$$\end{document} and 90%\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$90\%$$\end{document} of that observed in related works, respectively.

【Abstract】Blockchain technology has reshaped how members of supply chains transfer information, effectively avoiding the phenomenon of information silos and helping to improve the emissions reduction performance and profit of each subject in the supply chain. It is now critical to understand how supply chain members can be encouraged to collaboratively invest in low-carbon service platforms based on blockchain technology to realise chain-wide systematic carbon reduction. In this regard, considering the time-dynamic characteristics of enterprise emissions reduction, this paper establishes a differential game model of collaborative emissions reduction in a low-carbon supply chain composed of a Stackelberg leader manufacturer and a supplier. We compare and analyse the four investment decision scenarios regarding whether the supplier and manufacturer invest in the blockchain low-carbon service platform under decentralised decision-making, as well as the equilibrium solutions of supply chain members under centralised decision-making scenarios by solving the Hamilton function. Finally, we introduce a bilateral cost-sharing contract to make the supply chain perfectly coordinated. We find that the significant unit return is an important incentive for supply chain members to take the lead in investing in a low carbon service platform (LCSP). In this regard, when only one member invests, the other one demonstrates free-riding behaviour. Under centralised decision-making, the supply chain can achieve Pareto optimality, and the bilateral cost-sharing contract can achieve perfect coordination of the supply chain, which is the best choice for the decision-makers of low-carbon supply chains. As the influence level of the LCSP gradually increases from small to large, the optimal decision-making of supply chain members gradually transitions from waiting for the right time to "hitchhike" to a strong willingness to cooperate. This study is of great reference value and practical significance for economic entities to improve profits, promote systematic carbon reduction in the whole chain and promote the sustainable development of low-carbon supply chains.

【Abstract】We analyse National Basketball Association (NBA) digital collectibles' prices to test whether there exist any racial disparities based on NBA players' demographics. Using a novel and rich dataset, controlling for performance measures, we do not find evidence of price disparities between Black versus White players, Hispanic versus non-Hispanic players and foreign versus U.S. players. However, we find evidence suggesting that non-Black minority players' product prices are statistically and economically lower than those of comparable players. We also identify two possible channels which might contribute to such racial disparities - a product design channel and a media coverage channel.

【Abstract】Currently, there is no unified Electronic Health Record (EHR) system connecting major healthcare organizations such as hospitals, medical centers, and specialists. Blockchain technology, with its unique features, provides an ideal platform for developing a large-scale electronic health record system. In this article, the authors introduce HealthChain, a novel blockchain-based secure EHR system that integrates advanced encryption techniques, a robust consent management system, cross-platform interoperability, and enhanced scalability. Unlike existing EHR systems, HealthChain allows patients to have comprehensive control over their health data, ensuring that access is strictly regulated according to their preferences. The experimental results demonstrate several significant improvements over traditional EHR systems. HealthChain reduces data access times by 30%, and its interoperability rate with various healthcare systems is 40% higher than that of other blockchain-based EHR solutions. Security is greatly enhanced, with HealthChain experiencing 50% fewer data breaches due to its advanced encryption and smart contract-based access controls. Moreover, patient satisfaction has increased by 35% as a result of better control and access to their health records. These findings highlight HealthChain as not only a feasible and effective solution for managing health records but also a significant advancement over existing systems. Blockchain technology, with its unique features, provides an ideal platform for developing a large-scale electronic health record system. HealthChain, a blockchain-based secure Electronic Health Record (EHR) System, is introduced. The experimental results demonstrate several significant improvements over traditional EHR systems. image

【Abstract】The Cenozoic era is the digital age where people, things, and any device with network capabilities can communicate with each other, and the Internet of Things (IoT) paves the way for it. Almost all domains are adopting IoT from smart home appliances, smart healthcare, smart transportation, Industrial IoT and many others. As the adoption of IoT increases, the accretion of data also grows. Furthermore, digital transformations have led to more security vulnerabilities, resulting in data breaches and cyber-attacks. One of the most prominent issues in smart environments is a delay in data processing while all IoT smart environments store their data in the cloud and retrieve them for every transaction. With increased data accumulations on the cloud, most smart applications face unprecedented delays. Thus, data security and low-latency response time are mandatory to deploy a robust IoT-based smart environment. Blockchain, a decentralized and immutable distributed ledger technology, is an essential candidate for ensuring secured data transactions, but it has a variety of challenges in accommodating resource-constrained IoT devices. Edge computing brings data storage and computation closer to the network's edge and can be integrated with blockchain for low-latency response time in data processing. Integrating blockchain with edge computing will ensure faster and more secure data transactions, thus reducing the computational and communicational overhead concerning resource allocation, data transaction and decision-making. This paper discusses the seamless integration of blockchain and edge computing in IoT environments, various use cases, notable blockchain-enabled edge computing architectures in the literature, secured data transaction frameworks, opportunities, research challenges, and future directions.
