Industrial business-to-business (B2B) platforms are meta-organizations (i.e., organizations of organizations) that typically integrate digital assets with physical products such as machinery or equipment, often operating in specialized contexts with a limited network of complementors and end users. These characteristics distinguish B2B platforms from their business-to-consumer (B2C) counterparts, as they are defined by distinctive design features and governance drivers. Yet, the current platform literature predominantly focuses on B2C markets, leaving a critical gap in understanding the design and governance of B2B platforms in industrial contexts. We address this gap by adopting a meta-organizational perspective on B2B platforms in industrial markets to examine how the distinct design features of B2B platforms shape their meta-organizational governance. First, we uncover distinctive design features of B2B platforms across three dimensions: platform market, platform architecture, and cyber-physical integration. Building on these features and evidence from the emerging literature, we classify B2B platforms into five dominant archetypes: matchmaker, application marketplace, solution enabler, consortium, and decentralized autonomous platforms. Second, we theorize that the governance of these archetypes is shaped by their design features and revolves around two main dimensions: control rights (i.e., enforcement authority) and decision rights (i.e., autonomy over platform assets). These dimensions underpin distinct governance models, which we label unified, collaborative, regulated, and algorithmic governance. We consolidate these insights into an organizing framework of B2B platform governance and contribute to the literature in four ways: (1) providing a nuanced understanding of B2B platform design and governance, (2) identifying distinct archetypes and developing a framework for B2B platform governance, (3) explaining how B2B platform design features influence governance models, and (4) setting a research agenda to strengthen the design and governance of B2B platforms. By broadening our understanding of platforms as meta-organizations, we advance knowledge of how B2B platforms create and capture value in industrial markets. • We examine the distinct design features of B2B platform governance. • We identify five B2B platform archetypes based on their distinct design features. • B2B meta-organizational governance encompasses unique control and decision rights. • We identify unified, collaborative, regulated, algorithmic governance models. • Each governance model is characterized by different control and decision rights.

Twenty-five years ago, the specification of the Intelligent Product was established, envisaging real-time connectivity that not only enables products to gather accurate data about themselves but also allows them to assess and influence their own destiny. Early work by the Auto-ID project focused on creating a single, open-standard repository for storing and retrieving product information, laying a foundation for scalable connectivity. A decade later, the approach was revisited in light of low-cost RFID systems that promised a low-cost link between physical goods and networked information environments. Since then, advances in blockchain, Web3, and artificial intelligence have introduced unprecedented levels of resilience, consensus, and autonomy. By leveraging decentralised identity, blockchain-based product information and history, and intelligent AI-to-AI collaboration, this paper examines these developments and outlines a new specification for the Intelligent Product 3.0, illustrating how decentralised and AI-driven capabilities facilitate seamless interaction between physical AI and everyday products.

Solidity is the predominant programming language for blockchain-based smart contracts, and its characteristics pose significant challenges for code analysis and maintenance. Traditional software analysis approaches, while effective for conventional programming languages, often fail to address Solidity-specific features such as gas optimization and security constraints. This paper introduces micro-patterns - recurring, small-scale design structures that capture key behavioral and structural peculiarities specific to a language - for Solidity language and demonstrates their value in understanding smart contract development practices. We identified 18 distinct micro-patterns organized in five categories (Security, Functional, Optimization, Interaction, and Feedback), detailing their characteristics to enable automated detection. To validate this proposal, we analyzed a dataset of 23258 smart contracts from five popular blockchains (Ethereum, Polygon, Arbitrum, Fantom and Optimism). Our analysis reveals widespread adoption of micro-patterns, with 99% of contracts implementing at least one pattern and an average of 2.76 patterns per contract. The Storage Saver pattern showed the highest adoption (84.62% mean coverage), while security patterns demonstrated platform-specific adoption rates. Statistical analysis revealed significant platform-specific differences in pattern adoption, particularly in Borrower, Implementer, and Storage Optimization patterns.
The Industrial Internet of Things (IIoT) seeks to improve smart factory productivity by leveraging automation and scalability. For automation in industry, optimization, collaboration and protection, and scalability, the IoTs paradigm, technology for communication and information, and intelligent systems are integrated as a single organism. This article presents a blockchain-assisted safe data-sharing mechanism that provides security requirements in the industry using IoT. End-to-end authentication is developed based on the blockchain's reputation, and the smart contract is used to validate nodes' security measures. Through integrity verification and categorization in node terminals and industry, the blockchain paradigm manages data collection and dissemination. An efficient proof of authentication (PoAh) consensus mechanism is created using the blockchain network to build a collaborative network to preserve logs and verification data in the industrial IoT. It accomplishes trustworthy authentication and endpoint activity tracing, and edge computing is used in blockchain nodes to offer device authentication processes that utilize smart contracts and PoAh. According to an experimental study, the proposed architecture lowers the authentication time and obtains a high response rate. The proposed system's service time shows the efficiency of PoAh-based blockchain architecture for industrial IoT compared with existing works. Finally, we evaluated various block sizes to ensure an efficient transaction rate. The outcomes demonstrate the practicality of the suggested and put-into-practice architecture, distinguished by enhanced data audibility, device data ownership, security, and privacy while utilizing decentralized storage.
Many countries in the Asia Pacific rely on community health workers (CHWs) to care for various health needs. In the Greater Mekong Subregion (GMS), malaria CHWs have been an essential component of malaria elimination. Yet as the malaria burden declines, the role of malaria CHWs in local health systems and communities is changing. There is a need to expand malaria CHW roles to take on the provision of health services beyond malaria. This study sought to understand the process and experience of this role expansion including implementation, financing, policy, and sustainability within the Asia Pacific region. We documented malaria CHW programs that included health services in addition to malaria. We conducted 21 key-stakeholder interviews from thirteen programs in eight countries throughout the Asia Pacific region virtually in English and findings were analyzed using rapid-matrix analysis. Participants were recruited by an online landscaping survey, with an inclusion criterion of five + years' work experience and English speaking. Governments ran five of the thirteen programs; six were international non-governmental organizations (INGOs), and two were academic. Senior staff from programs that have expanded roles of malaria CHWs or integrated CHW programs explained expansion processes, challenges, and opportunities. We found that integration can occur in multiple program domains and does not necessarily occur in all domains simultaneously. We identified entry points for role expansion: integrated policy and financing, planning, assessments, and research. Operational entry points included the selection, training, motivation, management, supervision, and monitoring of CHWs. Enabling factors included decentralized management structures, health system linkages, commodity provision and referral procedures, and community engagement. While there is not a linear or unique path towards integration, we provide considerations for the policy level, practical implementation steps, and enabling factors for countries in the GMS to consider as they move towards sustainable, integrated malaria CHWs.

With the continuous development of technology, blockchain has been widely used in various fields by virtue of its decentralization, data integrity, traceability, and anonymity. However, blockchain still faces many challenges, such as scalability and security issues. Artificial intelligence, with its powerful data processing capability, pattern recognition ability, and adaptive optimization algorithms, can improve the transaction processing efficiency of blockchain, enhance the security mechanism, and optimize the privacy protection strategy, thus effectively alleviating the limitations of blockchain in terms of scalability and security. Most of the existing related reviews explore the application of AI in blockchain as a whole but lack in-depth classification and discussion on how AI can empower the core aspects of blockchain. This paper explores the application of artificial intelligence technologies in addressing core challenges of blockchain systems, specifically in terms of scalability, security, and privacy protection. Instead of claiming a deep theoretical integration, we focus on how AI methods, such as machine learning and deep learning, have been effectively adopted to optimize blockchain consensus algorithms, improve smart contract vulnerability detection, and enhance privacy-preserving mechanisms like federated learning and differential privacy. Through comprehensive classification and discussion, this paper provides a structured overview of the current research landscape and identifies potential directions for further technical collaboration between AI and blockchain technologies.
The rise of social media sites has far-reaching effects on numerous areas in our life, including money decision-making. In the context of cryptocurrency, a novel alternative asset class for investment the roles of social media have taken on more and more powerful roles in determining investors' behaviors, market structure, and even eco-consciousness. This paper aims to explore the intricate relationship between social media engagement and cryptocurrency investment trends, with a special emphasis on environmental considerations and market volatility. In this paper, we use wavelet comovement and coherence analysis to explore the multifaceted relationship between social media, environmental awareness, and cryptocurrency investment dynamics. Empirical results show a positive relationship between the Cryptocurrency Environmental Attention index-based social media which highlights the significant influence on investor attitudes. The interactions between the Index of Cryptocurrency Environmental Attention, cryptocurrency uncertainty, financial market, and gold demonstrate complex relationships shaped by market volatility, investor behavior, and social pressures. The quick investor responses to environmental concerns and regulatory changes highlight the short-term negative relationship, while the positive influence of social media underscores the significant impact of social awareness on investment decisions and corporate practices. This underscores the importance of integrating environmental criteria into financial strategies to meet evolving investor expectations and societal demands.
Cryptocurrency is a new type of asset that has emerged with the advancement of financial technology, creating significant opportunities for research. bitcoin is the most valuable cryptocurrency and holds significant research value. However, due to the significant fluctuations in bitcoin's value in recent years, predicting its value and ensuring the reliability of these predictions, which have become crucial, have gained increasing importance. A method that combines Long Short-term Memory (LSTM) with conformal prediction is proposed in this paper. Initially, the high-dimensional features in the dataset are divided using the Spearman correlation coefficient method, and features below 0.75 and above 0.95 are excluded. Subsequently, an LSTM model is built, and data are fed into it and the data is used to train the model to generate predictions. Finally, the predicted values generated by the LSTM are fed into the conformal prediction model, and confidence intervals for these values are generated to verify their reliability. In the conformal prediction model, the quantile loss of the loss function is defined, and an Average Coverage Interval (ACI) predictor is designed to improve the accuracy of the results. The experiments are conducted using data from CoinGecko, which is a publicly available data. The results show that the LSTM-conformal prediction (LSTM-CP) combination improves reliability.

To improve crop forecasting and provide farmers with actionable data-driven insights, we propose a novel approach integrating IoT, machine learning, and blockchain technologies. Using IoT, real-time data from sensor networks continuously monitor environmental conditions and soil nutrient levels, significantly improving our understanding of crop growth dynamics. Our study demonstrates the exceptional accuracy of the Random Forest model, achieving a 99.45\% accuracy rate in predicting optimal crop types and yields, thereby offering precise crop projections and customized recommendations. To ensure the security and integrity of the sensor data used for these forecasts, we integrate the Ethereum blockchain, which provides a robust and secure platform. This ensures that the forecasted data remain tamper-proof and reliable. Stakeholders can access real-time and historical crop projections through an intuitive online interface, enhancing transparency and facilitating informed decision-making. By presenting multiple predicted crop scenarios, our system enables farmers to optimize production strategies effectively. This integrated approach promises significant advances in precision agriculture, making crop forecasting more accurate, secure, and user-friendly.
The constitutionalising of local self-government through the 73rd and 74th Constitutional Amendments marked a significant moment in India’s democratic and federal evolution. These reforms sought to deepen democracy by devolving powers, responsibilities and resources to local governments. More than three decades later, decentralization in India has produced institutions that are electorally vibrant but administratively constrained. This paper examines the paradox of extensive formal devolution coexisting with persistent state control. Using the analytical framework of finance, functions, and functionaries (the “3Fs”), it argues that decentralization in India has unfolded as a managed and politically conditioned process rather than a comprehensive transfer of authority. While fiscal transfers and functional assignments have expanded unevenly, control over administrative personnel has remained firmly centralized. The retention of authority over functionaries emerges as the central mechanism through which state governments preserve power over local governance. The paper contributes to decentralization scholarship by shifting attention from constitutional design to political economy, highlighting personnel control as the key constraint on substantive local self-government in India.
Many educational institutions worldwide now use blockchain to verify electronic document, often relying on Ethereum 1.0, which uses proof of work (PoW) or proof of authority (PoA). However, Ethereum 2.0, launched in 2022 by Ethereum Foundation operates on proof of stake (PoS). This study provides comparative analysis of PoS and PoA consensus in Ethereum environment specifically focusing on performance and scalability in the context of academic transcript databases. To demonstrate this, a student academic reputation information system was developed using two different blockchain technologies: Ethereum 1.0 with PoA and Ethereum 2.0 with PoS. This setup was used to obtain comparative analysis data for the two blockchain systems by measuring the throughput and latency. We observed how these platforms responded to an increasing number and frequency of transactions with Hyperledger Caliper. Results indicates that in performance testing, both consensus mechanisms exhibited. Scalability tests revealed that both consensus mechanisms experienced increased latency with higher loads. However, PoA system was superior in average throughput and latency than PoS system except in high transaction of data addition. The experiment result show that PoA system better than PoS system in context of academic transcript databases, making it more suitable to be implemented on that context.
Decentralized Autonomous Organizations (DAOs) have emerged as one of the most disruptive innovations in governance, offering new frameworks for collective decision-making, transparency, and accountability in both public and private spheres. Rooted in blockchain technology and powered by smart contracts, DAOs eliminate the need for traditional hierarchical management by enabling rules to be self-enforced and decisions to be executed automatically. This paper examines DAOs as governance mechanisms, tracing their historical development, theoretical underpinnings, and practical implementations across finance, civic engagement, digital cooperatives, and resource management. Through an extensive literature review, comparative case studies, and thematic content analysis, the study highlights DAOs’ potential to reduce agency problems, enhance participatory governance, and ensure auditability through immutable ledgers. However, the analysis also reveals significant challenges, including legal ambiguity, technological vulnerabilities, token-weighted plutocracy, voter apathy, and scalability concerns that hinder their broader application. Results suggest that DAOs function effectively as experimental laboratories of algorithmic governance but are not yet fully equipped to replace traditional governance structures. Instead, hybrid models integrating decentralized decision-making with institutional oversight present the most viable path forward. By critically analyzing DAO case studies such as MakerDAO, ConstitutionDAO, and CityDAO, the study underscores their dual role as governance innovations and socio-political experiments that push the boundaries of trust, coordination, and autonomy in the digital age. The findings position DAOs not only as technological entities but also as frameworks capable of reshaping democratic practices, resource governance, and institutional legitimacy in the 21st century.

In the rapidly evolving Web3 world, non-fungible token (NFT) communities are reshaping the formation, distribution, and activation of social capital in ways distinct from traditional models. However, despite their growing impact on societal prosperity, a comprehensive understanding of social capital dynamics within Web3 NFT communities remains limited. This study explores the Mfers community, a key example within Web3 NFT ecosystems. By analyzing social media and blockchain data and using a Delphi method-based human-large language model (LLM) collaboration, we uncovered unique social capital patterns across six dimensions. Our findings highlight a compelling blend of decentralization, inclusion, trust, and empowerment but also raise critical questions about wealth inequality, content quality, and ethical challenges. Based on the findings, we discussed the uniqueness of social capital in Web3 NFT communities, the tension between technical and power decentralization, and the multidimensional nature of societal prosperity. We also suggested directions for future research on decentralized online communities in the CSCW field. This study provides a systematic perspective on social capital in Web3 NFT communities and introduces an innovative human-LLM collaborative analysis, offering insights into the design and governance of benign decentralized online communities.
This paper proposes a decentralized, blockchain-based system for the publication of Common Vulnerabilities and Exposures (CVEs), aiming to mitigate the limitations of the current centralized model primarily overseen by MITRE. The proposed architecture leverages a permissioned blockchain, wherein only authenticated CVE Numbering Authorities (CNAs) are authorized to submit entries. This ensures controlled write access while preserving public transparency. By incorporating smart contracts, the system supports key features such as embargoed disclosures and decentralized governance. We evaluate the proposed model in comparison with existing practices, highlighting its advantages in transparency, trust decentralization, and auditability. A prototype implementation using Hyperledger Fabric is presented to demonstrate the feasibility of the approach, along with a discussion of its implications for the future of vulnerability disclosure.
This study examines the feasibility and profitability of utilizing surplus electricity for Bitcoin mining. Surplus electricity refers to the remaining electricity after net metering, which can be repurposed for Bitcoin mining to improve Korea Electric Power Corporation's (KEPCO) energy resource efficiency and alleviate its debt challenges. Net metering (or net energy metering) is an electricity billing mechanism that allows consumers who generate some or all of their own electricity to use that electricity when they want, rather than when it is produced. Using the latest Bitcoin miner, the Antminer S21 XP Hyd, the study evaluates daily Bitcoin mining when operating at 30,565 and 45,439 units, incorporating Bitcoin network hash rates to assess profitability. To examine profitability, the Random Forest Regressor and Long Short-Term Memory models were used to predict the Bitcoin price. The analysis shows that the use of excess electricity for Bitcoin mining not only generates economic revenue, but also minimizes energy loss, reduces debt, and resolves unsettled payment issues for KEPCO. This study empirically investigates and analyzes the integration of electricity surplus in South Korea with bitcoin mining for the first time. The findings highlight the potential to strengthen the financial stability of KEPCO and demonstrate the feasibility of Bitcoin mining. In addition, this research serves as a foundational resource for future advancements in the Bitcoin mining industry and the efficient use of energy resources.
The initial driving force behind the development of the cryptocurrency market is the Bitcoin currency. The emergence and expansion of specialized exchanges were essential for trading this cryptocurrency. Consequently, experts in the field recognized the necessity of developing econometric models to forecast Bitcoin’s exchange rate. Proposals presented by econometricians at scientific conferences demonstrated that such models could help minimize risks and potential losses during the stages of investing in Bitcoin and selecting financial instruments, as well as forecast future returns. In this article, we attempt to present methods for constructing predictive econometric models to automate cryptocurrency trading and analyze Bitcoin’s price fluctuations using econometric modeling techniques. The economic development of the cryptocurrency market, the technological architecture of Bitcoin, and the principles of econometric modeling have been systematically examined, and the data were analyzed based on real statistical information. The article is structured in logical order, and the conclusions and recommendations are presented with scientific justification. The statistical methods, analytical charts, and forecasting models used in the study were selected according to the research topic, and the results are expressed clearly and in a scientific manner. The article’s plagiarism index is below 5%, which confirms its status as a fully original scientific work.
Blockchain technology introduces a new decentralized paradigm era avoiding the reliance on trusted third parties. It is a transparent and distributed ledger which is designed fundamentally for digital cryptocurrencies but has since been extended to various industries. However, its immutability obligates significant challenges including storing illicit contents, privacy regulations violations, and restricting data management flexibility. Therefore, redactable blockchain has emerged as a leading solution enabling controlled immutable contents amendment. Transaction-level redaction reinforced by fine-grained access control forms the cornerstone of the current redaction mechanisms. This redaction concept essentially depends on modifying mutable transactions governed by predefined access policies specified by the transaction owner. Modifiers equipped with necessary rewriting privileges and who fulfil the associated access policy are enabled to perform modifications. However, the existing redaction mechanisms infrastructures are inefficient. For instance, the chameleon hash ephemeral trapdoor (chet),
This article critically evaluates the Sharia legitimacy of Bitcoin by applying Usul al-Fiqh—the foundational principles of Islamic jurisprudence—to several influential fatwas that prohibit it. Despite stemming from sincere concerns, many such fatwas rely on incomplete factual understanding, unverified analogies, or secondary policy considerations rather than explicit textual or consensus-based evidence. Consequently, these rulings risk conflating genuine harms (fraud, volatility, illicit use) with Bitcoin’s inherent characteristics, which classical fiqh frameworks may otherwise recognize as permissible if carefully regulated. Drawing on examples of fatwas that deem Bitcoin permissible, the study demonstrates how thorough subject comprehension and methodologically robust legal derivation (ijtihad) often yield more nuanced conclusions. It further underscores that well-established Qur’anic and Prophetic principles— such as avoiding excessive uncertainty (gharar) and upholding wealth preservation—need not preclude thoughtful, evidence-based engagement with emerging financial technologies. Concluding that clear methodological grounding and accurate technology assessment are indispensable, the paper advocates ongoing dialogue between Sharia scholars, economists, and technical experts to ensure balanced rulings that protect Muslims’ interests while fostering innovation.
