【Abstract】Combined heat and power dispatch (CHPD) has aroused widespread attention nowadays due to its great potentiality and cost-effectiveness for wind accommodation. However, the CHPD requires the joint operation of multiple energy agents, and the traditional dispatch scheme is inapplicable in engineering practice due to the demand for privacy preservation among energy agents. To tackle this issue, a privacy-preserving method based on the information masking (IM) mechanism is proposed, which converts the original CHPD problem into another masked CHPD problem by obscuring the privacy parameters of the electric power systems and district heating systems. Furthermore, considering the absence of a third party in practice, we develop an improved IM mechanism based on blockchain, enabling privacy preservation in a fully decentralized framework. Numerical simulations conducted across different cases testify the effectiveness of the proposed privacy-preserving method and tests based on an actual system in Jilin province demonstrate the feasibility of application in practice. The computational performance of the proposed method is validated as well.

【Abstract】Blockchain technology (BCT) plays a pivotal role in ensuring cost-effective carbon trading and establishing customers' trust. In this paper, we consider the combination of hybrid carbon trading schemes and blockchain technology and model a carbon trading supply chain, in which traditional and renewable energy manufacturers coexist. Within this supply chain, BCT adoption facilitates the recording of carbon trading information and simplifies the transaction process when traditional energy manufacturers procure Certified Emission Reductions (CERs) from renewable energy manufacturers. However, the substantial upfront investment costs pose a barrier to the widespread application of BCT in carbon trading processes. To address this, we introduce the cooperative investment strategy by proposing a novel biform game model framework combining the noncooperative and cooperative games, exploring the competitive strategies (the pricing strategies and BCT level decisions) and cooperative investment strategies within the same model. By comparing with noncooperative cases, in which the supply chain agents engage in BCT investment on a competition basis, our findings reveal several thresholds of competition intensity where cooperative-investment strategies induce Pareto improvements in economic performance and individual profits compared to non-cooperative strategies. These findings have significant implications for firms who adopt BCT to engage in carbon trading schemes.

【Abstract】The Metaverse is an evolving technology that leverages the Internet infrastructure and the massively connected Internet of Everything (IoE) to create an immersive virtual world. In the Metaverse, humans engage in activities similar to those in the real world, such as socializing, working, attending events, exploring virtual landscapes, creating and trading digital assets, participating in virtual economies, and experiencing entertainment and cultural activities. By using advanced technologies such as IoE, extended reality (XR), artificial intelligence (AI), machine learning (ML), and 6G communication, along with blockchain technology, the Metaverse bridges the physical and virtual worlds. In particular, Blockchain-Enabled IoE (BIoE) will play a crucial role in Metaverse applications by ensuring secure service provisioning through the integration of blockchain with IoE. It efficiently manages the massive connectivity of physical world objects and enhances security, integrity, and decentralization of trust, while increasing resilience against failures, thus securing and fostering trust in both physical and virtual Metaverse networks. While some view the Metaverse as a detached virtual world, technologies like mixed reality and digital twins highlight the need for complementarity and interactive coexistence between the physical and virtual worlds. Blockchain facilitates this co-existence by providing a secure and trusted framework for integrating and synchronizing data and activities across both environments, developing trust through the reliability and authenticity of interactions and transactions. However, despite substantial advancements in related fields, there remains a significant gap in comprehensive surveys that address the integration of AI/ML, 6G, and blockchain in the Metaverse. In this paper, we fill this gap by examining BIoE's capabilities in bridging the physical and virtual worlds and securing Metaverse applications across various domains, such as immersive energy grids, immersive healthcare, and immersive living. We explore BIoE's role in service provisioning in the Metaverse, including access control, privacy protection, authentication, attack identification, and trust management. Additionally, we present a detailed taxonomy of existing literature, discuss novel use cases, and explore the synergies and practical implementations of BIoE in Metaverse applications. Finally, we address current challenges and propose future research directions to advance the field of BIoE in the Metaverse.

【Abstract】This study investigates the return and volatility interconnectedness between emerging digital assets, specifically agricultural tokens, and U.S. equity sectors using the TVP-VAR model. Analyzing data from August 7, 2020, to January 2, 2024, the findings indicate modest interconnections between agricultural tokens and U.S. sectors, with time-varying behavior. Notably, return interconnectedness is generally stronger than volatility, except at the sample period's outset, where volatility dominates. Return spillovers predominantly drive the connectedness system, though agricultural tokens uniquely act as net recipients of both return and volatility spillovers, while U.S. equity sectors mainly transmit spillovers. Optimal portfolio analysis, utilizing portfolio weights and hedge ratios, reveals that incorporating agricultural tokens offers portfolio diversification benefits and enhances hedging performance. Investors are advised to frequently adjust portfolios to maximize diversification and hedging gains. These findings provide significant portfolio implications for policymakers, market participants, and investors.

【Abstract】Amidst increasing interest from investors and scholars in the emerging Metaverse market, this paper marks a pioneering attempt to investigate the volatility connections between the Metaverse stock index and traditional financial markets such as Gold, Crude Oil, the Volatility Index, Bitcoin, and the Nasdaq. Utilizing a novel Quantile Vector Autoregressive (QVAR) model, the study assesses the transmission of shocks between the Metaverse market and its counterparts during bearish, normal, and bullish market conditions. The results highlight a significant increase in connectivity during extreme conditions compared to median levels. Notably, the Nasdaq emerges as a principal volatility transmitter to the Metaverse index, while Bitcoin shows minimal influence, suggesting that technological innovations, rather than cryptocurrencies, predominantly drive the Metaverse market. This investigation provides valuable insights for investors and policymakers, considering the nascent stage of Metaverse-related empirical research.

【Abstract】PurposeThe disconnect between producers and consumers is a fundamental issue causing irregularities, inefficiencies and leakages in the agricultural sector, leading to detrimental impacts on all stakeholders, particularly farmers. Despite the potential benefits of Metaverse technology, including enhanced virtual representations of physical reality and more efficient and sustainable crop and livestock management, research on its impact in agriculture remains scarce. This study aims to address this gap by identifying the critical success factors (CSFs) for adopting Metaverse technology in agriculture, thereby paving the way for further exploration and implementation of innovative technologies in the agricultural sector.Design/methodology/approachThe research employed integrated methodology to identify and prioritise critical success criteria for Metaverse adoption in the agricultural sector. By adopting a mixed-method technique, the study identified a total of 15 CSFs through a literature survey and expert consultation, focusing on agricultural and technological professionals and categorising them into three categories, namely "Technological", "User Experience" and "Intrinsic" using Kappa statistics. Further, the study uses grey systems theory and the Ordinal Priority Approach to prioritise the CSFs based on their weights.FindingsThe study identifies 15 CSFs essential for adopting Metaverse technology in the agricultural sector. These factors are categorised into Technological, User Experience-related and Intrinsic. The findings reveal that the most important CSFs for Metaverse adoption include market accessibility, monetisation support and integration with existing systems and processes.Practical implicationsIdentifying CSFs is essential for successful implementation as a business strategy, and it requires a collaborative effort from all stakeholders in the agriculture sector. The study identifies and prioritises CSFs for Metaverse adoption in the agricultural sector. Therefore, this study would be helpful to practitioners in Metaverse adoption decision-making through a prioritised list of CSFs in the agricultural sector.Originality/valueThe study contributes to the theory by integrating two established theories to identify critical factors for sustainable agriculture through Metaverse adoption. It enriches existing literature with empirical evidence specific to agriculture, particularly in emerging economies and reveals three key factor categories: technological, user experience-related and intrinsic. These categories provide a foundational lens for exploring the impact, relevance and integration of emerging technologies in the agricultural sector. The findings of this research can help policymakers, farmers and technology providers encourage adopting Metaverse technology in agriculture, ultimately contributing to the development of environment-friendly agriculture practices.

【Abstract】Recent Byzantine Fault-Tolerant (BFT) State Machine Replication (SMR) protocols increasingly focus on scalability and security to meet the growing demand for Distributed Ledger Technology (DLT) applications across various domains. Current BFT consensus algorithms typically require a single leader node to receive and validate votes from the majority process and broadcast the results, a design challenging to scale in large systems. We propose a fast-response consensus algorithm based on improvements to HotStuff, aimed at enhancing transaction ordering speed and overall performance of distributed systems, even in the presence of faulty copies. The algorithm introduces an optimistic response assumption, employs a message aggregation tree to collect and validate votes, and uses a dynamically adjusted threshold mechanism to reduce communication delay and improve message delivery reliability. Additionally, a dynamic channel mechanism and an asynchronous leader multi-round mechanism are introduced to address multiple points of failure in the message aggregation tree structure, minimizing dependence on a single leader. This adaptation can be flexibly applied to real-world system conditions to improve performance and responsiveness. We conduct experimental evaluations to verify the algorithm's effectiveness and superiority. Compared to the traditional HotStuff algorithm, the improved algorithm demonstrates higher efficiency and faster response times in handling faulty copies and transaction ordering.

区块链应用-实体经济-食品领域
【Abstract】This study examines how smart food-sharing platforms (SFSP) can help reduce food waste and suggests a method for using smart contracts to share extra food among different partners effectively. For smart contracts to work automatically and prevent food wastage, artificial intelligence systems can recognize how smart clauses should be executed. This will involve analyzing several factors like the selling price, expiration dates, offers from other partners, transport costs, wholesale price, shelf life, donation rates, and demand rates. The findings indicate that adopting an SFSP is an efficient solution for preemptively adopting redistribution strategies and improving social outcomes through donations as well as achieving positive environmental outcomes through reduced waste. However, we also identify cases in which reducing food waste to achieve social sustainability may negatively impact economic performance.

【Abstract】It is encouraging to see blockchain technology take off as a practical means of improving supply chain management. Blockchain can help to lower fraud, boost efficiency, and improve the trust of those involved in the supply chain by offering a secure, decentralized, and transparent platform for tracking and verifying transactions. Additionally, blockchain can help with the creation of smart contracts, which can automate the completion of some transactions and improve the supply chain's overall efficiency. Despite ongoing challenges like scalability and interoperability, blockchain technology has the potential to transform supply chain management and build a more robust, sustainable, and reliable global economy. To increase transparency, accountability, and trust in the supply chain, this article suggests using a Proof of Reputation (PoR) consensus protocol in a blockchain-based supply chain management system. The protocol gives each participant a reputation score based on their previous actions and behavior, and uses this score to securely and decentralized validate transactions and add new blocks to the blockchain. The article offers a collection of Fair-Exchange Assessment Metrics for assessing node reputation as well as an assessment model for choosing the best consensus protocol based on particular needs and objectives. The proposed model, BCSC, outperforms the current model, BRBC, in terms of interference ratio, fair data exchange ratio, and process overhead, according to experimental results. The suggested method has the potential to boost the security, scalability, and effectiveness of supply chain blockchain systems.

【Abstract】The inherent distributed and anonymity features of the blockchain system may cause illegal activities like improper content dissemination, illegal transactions, money laundering, etc., posing a severe threat to the blockchain. Due to the ultra-large scale of the public chain system, identifying key nodes in the transaction network is usually cost-intensive and time-consuming. In this paper, we propose a transaction graph-based scheme to identify key nodes in the public blockchain, where a multi-stage key node detection algorithm is proposed. Real Ethereum transaction data validates the performance of the proposed scheme. It is shown that with a data volume of millions of items, our multi-stage approach can effectively eliminate low-value information from the data and realize high-efficiency key node detection, with similar performance compared to traditional algorithms without filtering, and an extremely large improvement in algorithm execution time.

【Abstract】Consumer research has extensively explored digital ownership and possession, focusing on the entities owned, the owners, and their relationships to their possessions. This paper advances this literature by introducing the concept of "ownership technologies," as an analytical lens to attend to the technological devices and techniques that mediate ownership (shape social arrangements and interpretations of what constitutes ownership, what can be owned, who can own, and how). We illustrate the utility of this lens by providing historical examples, as well as through the prism of contemporary technologies such as blockchains and NFTs. We identify three ways in which technology mediates ownership-demarcation, enclosure, and transferability-and conclude by suggesting directions for future research on digital ownership.

区块链应用-实体经济-碳交易
【Abstract】To address the growing demand for green development, governments worldwide have introduced policies to promote a green economy. Among these policies, the carbon cap-and-trade mechanism is adopted as an effective approach to control carbon emissions. Additionally, blockchain may increase transparency in the industrial process. Despite focusing on improving its own green standards, the supply chain needs to establish stable cooperative relationship. Thus, we focus on a supply chain consisting of a dominant manufacturer and a retailer, where the manufacturer opts for implementing blockchain and the retailer selects their stance on fairness. We construct a Stackelberg game model and use backward induction to obtain the equilibrium solutions. In the supply chain, the highest profits can be achieved when the manufacturer adopts blockchain technology, provided that the cost of application is relatively low. For manufacturer and retailer, when the cost of applying blockchain is relatively low, they can both obtain maximized profits without applying blockchain and the retailer does not have fairness concerns. However, as the cost of inducing blockchain and the product's reduction in carbon emission increase, the optimal strategies for manufacturer and retailer begin to diverge, which may affect the stability of the supply chain.

【Abstract】The rapid development of artificial intelligence (AI) and 5G paradigm brings infinite possibilities for data annotation for new applications in the industrial Internet of Things (IIoT). However, the problem of data annotation consistency under distributed architectures and growing concerns about issues such as data privacy and cybersecurity are major obstacles to improving the quality of distributed data annotation. In this paper, we propose a reputation-based asynchronous federated learning approach for digital twins. First, this paper integrates digital twins into an asynchronous federated learning framework, and utilizes a smart contract-based reputation mechanism to enhance the interconnection and internal interaction of asynchronous mobile terminals. In addition, in order to enhance security and privacy protection in the distributed smart annotation system, this paper introduces blockchain technology to optimize the data exchange, storage, and sharing process to improve system security and reliability. The data results show that the consistency of our proposed FedDTrep distributed intelligent labeling system reaches 99%.

区块链技术-协同技术-共识机制
【Abstract】This study analyzes the security implications of Proof-of-Work blockchains with respect to the stale block rate and the lack of a block verification process. The stale block rate is a crucial security metric that quantifies the proportion of rejected blocks in the blockchain network. The absence of a block verification process represents another critical security concern, as it permits the potential for invalid transactions within the network. In this article, we propose and implement a quantitative and analytical model to capture the primary operations of Proof-of-Work blockchains utilizing the Performance Evaluation Process Algebra. The proposed model can assist blockchain designers, architects, and analysts in achieving the ideal security level for blockchain systems by determining the proper network and consensus settings. We conduct extensive experiments to determine the sensitivity of security to four aspects: the number of active miners and their mining hash rates, the duration between blocks, the latency in block propagation, and the time required for block verification, all of which have been shown to influence the outcomes. We contribute to the findings of the existing research by conducting the first analysis of how the number of miners affects the frequency of stale block results, as well as how the delay in block propagation influences the incentives received by rational miners who choose to avoid the block verification process.

区块链治理-技术治理-欺诈犯罪
【Abstract】It is commonly assumed that features of cryptocurrency such as its pseudo-anonymity and transnationality will be attractive to criminals. However, the public nature of the Blockchain questions the usefulness of this technology for crime. The aim of this research is to find out whether there are characteristics that are more attractive for the use of Bitcoin in crime. A qualitative analysis of the content of a Darknet forum was conducted. The term "Bitcoin" was used, and discussions were selected according to a previously conducted coding. Themes of interest were identified, and analysis was carried out using NVivo software. The discussions were categorized into themes: evading detection by authorities, exploiting cryptocurrencies for crime, recommendations, lessons in cybersecurity, regulation, and strategies to prevent victimization. The findings reveal that the critical factor is not the selection of a specific cryptocurrency but rather the establishment of conversion routes to circumvent traceability. Furthermore, the use of mixers, which are generally disapproved of within the community, is not recommended. Lastly, ample information is accessible for individuals to autonomously engage with this technology. In conclusion, while it is presumed to be a useful instrument for criminal activities, there are instances where alternative tools, including cash, are preferred.

【Abstract】Privacy and auditability have been conflicting design requirements for blockchain-based distributed ledgers since the inception of the field. As purpose-built blockchains with permissioned consensus and client access are developing in a broad and diverse range of industries, a specific form of this dichotomy is emerging: the need to audit the handling of regulated on-ledger financial assets, such as central bank digital currencies, while preserving the privacy and confidentiality of transactions as much as possible. This paper proposes a novel, privacy-preserving, noninteractive-zero-knowledge-proof-based protocol for a blockchain-based distributed ledger, to prove conformance with fundamental compliance requirements to external auditing parties. We present an extendable implementation and demonstrate the practicality of the approach.

【摘要】伪造数字货币的对象指向、伪造性以及规制路径存在分歧,有待进一步厘清。“货币”属于“经验性”法律概念,应回归本体论,在共识本质上明晰数字货币指向于央行数字货币。纯粹理性思辨使伪造说与不可伪造说陷入二律背反。从技术实践解构,数字货币具备伪造性,包括以假充真、以“真”充真两种行为方式。在入罪路径上,应对悖于解释学、类型学原理的解释论、立法论进行批判性解构。伪造数字货币行为与伪造货币罪的构成要件行为不同质,且侵犯法益具备独立性,不能通过刑法解释将其入罪;伪造数字货币行为的社会危害程度与侵入系统、非法获取持有相关信息、非法使用行为有别,过度类型化不符合罪责刑相适应原则,不宜将上述行为规整为一罪。同时,从货币共识涵摄视角倡导修正的单设论,采取分步走立法路径,实体货币与数字货币共存时,设立伪造数字货币罪,形成与伪造货币罪的二元规制体系;货币共识仅涵摄数字货币时,回归伪造货币罪一元规制体系。

【摘要】本文的目的是建立刻画区块链生态系统行为表现的“共识博弈”的一般框架,并针对“矿池间隔博弈”的“共识均衡”的存在性进行刻画和解读。特别是通过引进共识博弈这个新概念作为出发点,尽管区块链平台生态本身会受到诸如挖矿间隔等行为的干扰,我们证明了在合理的激励机制下一般区块链平台的共识博弈均衡点的存在性,从正面的角度回答了区块链生态本身发展是否稳定这个非常基本和核心的问题。这里,“间隔博弈”(不良)行为出现所在的区块链生态是指基于Nakamoto在2008年提出的遵循按照最长主链建设的“工作量证明”作为基本的共识原则的挖矿平台。特别地,本文首先在一般激励机制条件下,基于区块链生态中的共识博弈框架,在有挖矿间隔等不良行为出现的情况下,建立了在一般激励相容机制条件下的共识均衡点的存在性结果和对应区块链生态能够持续运转的稳定性解读;然后结合在“挖(币)矿”工作中涉及到的工作费用、奖励机制和挖矿能力这三类描述激励机制的核心要素,从挖矿工(组)收益的角度,针对不同嵌入场景对挖矿工(组)的“间隔博弈行为”可能产生的影响进行了解读和分析。本文的理论结果和案例分析表明,结合不同挖矿场景相合适的激励相容机制,共识博弈(均衡)这个概念可以在理论的层面(即,不需要情景数据模拟结果的支持),能够得到或形成针对不同场景下的挖矿行为的解释和解读。此外,我们有理由期待和相信,结合影响挖矿(组)收益相关的要素因子,共识博弈可以帮助我们构建对应的合适场景的激励相容机制,通过刻画挖矿工(组)出现的诸如“间隔行为”,“分叉链”,“矿池攻击”等(不良)行为,支撑数字经济的健康发展,并对共识经济学基础理论的发展能够起到推进作用。
