We have been witnessing an unprecedented increase in the aging population in human history. It is nontrivial to ensure the health and safety of seniors living alone. The prohibitive human labor cost necessitates more sustainable, technology-oriented approaches instead of labor-intensive solutions. The raising digital healthcare services (DHS) leveraging the Internet of Medical Things (IoMT), Digital Twins (DT), and advanced fifth-generation and beyond (B5G) wireless communication technology, are widely recognized as promising solutions. By enabling a seamless interwoven of the physical world and cyberspace, Metaverse makes an ideal home for the next generation of DHS. Thanks to characteristics of decentralization, traceability, and unalterability, Blockchain is envisioned to enhance security properties in Metaverse. This paper proposes MetaSafe, a DHS architecture for seniors’ safety monitoring in Metaverse. Based on monitoring data collected by sensors, the activities and status of seniors, who are considered as the physical objects (PO), are mirrored to corresponding logical objects (LO) in a virtual community in the Metaverse, where activity recognition, potential risk prediction, and alert generation are realized. By leveraging Non-Fungible Token (NFT) technology to tokenize identities (POs and LOs) and data streams of the DHS on the blockchain, an NFT-based authentication fabric allows for verifiable ownership and traceable transferability during the data-sharing process. Specifically, an instant alerting system is introduced in this work that leverages a hybrid algorithm combining the singular spectrum analysis (SSA) approach with the long-short-term memory (LSTM) networks. Through an extensive experimental study, MetaSafe is validated as a feasible and promising approach to protect seniors living alone.

Due to technological advancements and consumer demands, online shopping creates new features and adapts to new standards. A robust customer satisfaction prediction model concerning trust and privacy platforms can encourage an organization to make better decisions about its service and quality. This study presented an approach to predict consumer satisfaction using the blockchain-based framework combining the Multi-Dimensional Naive Bayes-K Nearest Neighbor (MDNB-KNN) and the Multi-Objective Logistic Particle Swarm Optimization Algorithm (MOL-PSOA). A regression model is employed to quantify the impact of various production factors on customer satisfaction. The proposed method yields better levels of measurement for customer satisfaction (98%), accuracy (95%), necessary time (60%), precision (95%), and recall (95%) compared to existing studies. Measuring consumer satisfaction with a trustworthy platform facilitates to development of the conceptual and practical distinctions influencing customers' purchasing decisions.

Due to its qualities that offer unbreakable security and global accessibility, blockchain has grown to become one of the most widely used technologies today. Blockchain technology is revolutionizing the financial and banking sectors, but it isn't only the financial sector; the majority of companies that used online payment systems, faced an issue with transparency or wished to do away with the middleman and also wish to incorporate it. NFT is a further emerging technology that is seen as a subset of the blockchain (NFT stands for the non-fungible token). NFT is merely a digital token that is awarded to any original creation, such as a painting or a song and or a tweet. This study examines the drawbacks of blockchain and NFT as they are faced by several industries, including IoT, banking, music, agriculture, food and supplies, and healthcare.

Loyalty platforms are designed to increase customer loyalty and thus increase consumers’ attraction to purchase. Although successful in increasing brand reach and sales, these platforms fail to meet their primary objective due to a lack of incentives and encouragement for customers to return. Along with the problem in originating sales, they bring excessive costs to brands due to the maintenance and infrastructure required to make the systems feasible. In that sense, recent blockchain technology can help to overcome some of these problems, providing capabilities such as smart contracts, which have the potential to reinvent the way loyalty systems work and solve current problems. Although blockchain is a relatively new technology, some brands are already investigating its usefulness and rebuilding their loyalty systems. However, these platforms are independent and linked directly to a brand. Thus, there is a need for a generic platform capable of creating and managing different loyalty programs, regardless of the size of the business. This paper explores the shortcomings of current loyalty programs identified through the literature review, and proposes a loyalty management system with blockchain integration that allows any retailer to create and manage their loyalty programs and have customers interact directly with multiple programs in a single application.

E-commerce platforms enable companies of all sizes to sell their items and promote their brand to a broader audience. The e-commerce sector is continually developing, as new technology and methods of purchasing and selling services and items are developed. The traditional e-commerce system is plagued with problems, such as payment disputes, chargebacks, fraud, and a lack of transparency; however, blockchain can transform e-commerce by making transactions more efficient and safer. Blockchain can be used to build a decentralized network that allows people to securely store and share digital assets. This would enable buyers to access product details such as the product’s origin and source, as well as reduce the risk of fraud. Although the application of blockchain in e-commerce remains in its early stages, this review paper examines research on blockchain-based e-commerce, focusing on applicability and problems in the context of the available literature from 2017 through 2022.

The traceability of what we eat is a lingering issue. Blockchain enables transparency across the value chain as it tracks a product’s origin, location, and history. In this work we adopt a mix-method approach - experiment plus qualitative evidence - to understand why consumers consider the traceability offered by blockchain important and what are the barriers that suppliers face when considering blockchain adoption. Our findings show that, when the food is local, blockchain increases consumers’ trust and, in turn, attitudes and behaviors toward the sharing experience. On the supply side, we find that, while operators see key benefits in blockchain adoption – including enhanced trust, they are still hesitant in using the technology because of a greater need for intra-organizational support and a concern in data sharing. By looking at both consumers and suppliers, we offer a complete picture on the integration of blockchain technology in the food supply chain.

The global fashion industry is a trillion US dollar market and one of the most wasteful industries in the world. Digital fashion has the potential to decouple some crucial aspects of the fashion industry from their material requirements. Combined with the growing interest around the metaverse, non-fungible tokens, the rapid evolution of AR and VR technology, and the growing presence of major fashion brands in gaming, an understanding of the commercial feasibility of digital fashion is becoming increasingly relevant. In this article, we explore the commercial feasibility of digital fashion and expose a strategically significant alignment of digital substitutes with four emerging consumer expectations, i.e., excitement, utility, relatability, and circularity. Our research shows that these expectations are contingent on consumers’ increasingly sufficiency-oriented mindset and the modes of consumption this mindset generates. By developing what we call a ‘sufficiency-model’, this article provides companies with the heuristic tools necessary to gain future-looking and practical insight that helps them navigate this dematerialization of consumption and to identify long-term market opportunities within this area. Specifically, we offer eight implications that are designed to help companies take their first steps into this emerging space.

This study investigates the effects of blockchain technology scalability limitations on the performance of Blockchain-Based Shared Manufacturing (BBSM), an innovative smart-manufacturing paradigm aimed at enhancing the utilization of global manufacturing resources via peer-to-peer (P2P) collaboration of self-organized manufacturing assets. Despite the prevalence of research highlighting blockchain technology’s scalability limitations as the main barrier for adoption, few studies have explored their effects on the operation of blockchain-based systems. The primary goal of the presented research work is to explore the implications of blockchain technology scalability limitations on the BBSM system’s performance and user behavior. To obtain realistic behavior, an experiment is conducted using an online game played by human participants. Analysis of the players’ strategy is used for implementation of a multi-agent simulation model, which is then employed to assess the influence of varying blockchain network configurations on the BBSM concept’s performance. Preliminary experimental findings reveal that a congested blockchain network leads to increased transaction costs and reduced service prices, consequently devaluing the manufacturing role in the BBSM system and causing underutilization of existing maximum production capacities. Moreover, allocating funds to financial activities rather than manufacturing activities yields superior outcomes for system users. Simulation results indicate that the BBSM system’s response to alterations in blockchain network throughput is contingent upon the production function. The findings of this study reveal that the scalability limitations of blockchain technology impair the performance of the BBSM system and affect user behavior in the system, underscoring the necessity for future research to concentrate on incorporating scalable solutions within blockchain-based manufacturing systems.

Blockchain-enabled advances (BEAs) are state-of-the-art innovations based on blockchain technology. Recent years have witnessed the proliferation of the four BEAs: smart contracts, cryptocurrencies, play-to-earn games, and non-fungible tokens. These BEAs have implications for the marketing field as they affect consumers and brands. We propose a novel theoretical framework that articulates how the principles that underpin BEAs can impact consumers and then explains how brands can use BEAs to innovate their products and services. The core principles of blockchain technology, as well as enhanced digital connectivity, imply that consumers can become more in control of their data and privacy rights, responsible for their choices, and digitally connected. To cater to consumers, brands can use BEAs to roll out technology-focused service innovations, customer-focused service innovations, and product innovations. Based on this perspective, we then advance ten future research questions. This article aims to advance the nascent field of blockchain in marketing.

The rapidly growing e-commerce sector has created new opportunities and challenges to the logistics industry. Nonetheless, the majority of Hong Kong logistics industry, especially small-and-medium (SMEs) firms, lack operational decision support to adequately handle the seasonal, fragmented, and fluctuating e-commerce orders. To grasp the opportunities of the e-commerce logistics business, logistics service providers (LSPs) should enhance their capability in information exchange and operational planning. With these improvements, the logistics industry would be better able to sustain and expand their e-commerce logistics business. In this paper, a Blockchain-based E-Commerce Analytics Model is developed to enhance digital supply chain integration. Firstly, timely operational decision support would be achieved as blockchain technology, after that, the ML algorithm would enable the logistics industry to manage data efficiently and to forecast dynamic e-commerce order demand. Subsequently, the proposed model allows LSPs to flexibly re-allocate the right number of resources in real time to deal with the hour-to-hour fluctuating arrival of orders in distribution centers. Additionally, the proposed model enables logistics practitioners to predict the sales performance related to e-commerce.

With the worldwide pandemic outbreak, the style of restaurant food consumption underwent a major shift towards online delivery services. This poses an urgent need in trust between main stakeholders of the process: requiring restaurants to correspond to the quality declared, providing high quality and safe to consume meals, and obliging delivery entities to deliver food carefully, scrupulously following the delivery conditions. In this research, we explore a novelty approach that combines IoT, Blockchain technology, and city LoRa network to create a new trusted, decentralized approach for food distribution process in the context of a Smart City. This approach allows controlling the food delivery process using sensors data to control live location, temperature, vibrations, and shakings during the transportation process. We also suggest a fresh perspective on a rating system of delivery entities, where reputation points will be provided both from the side of the restaurant and the final consumer. This will create more trust towards the delivery entity since information will be tamper-proof and immutable due to the nature of Blockchain. This novel system proposal allows rethinking the online food delivery process in the context of Smart City, using the city's LoRa LPWAN radio frequency technology and Blockchain decentralized solution.

Blockchain technology is predicted to become a powerful driver of marketing transformation. At present, most envisioned use cases are in an early stage with an uncertain industrial impact and an immature theoretical integration in academic research. To help close this research gap, we investigate how blockchain-based loyalty programs transform B2C relations through innovative customer services that bear important properties of a sharing economy. Specifically, we identify-five potential advantages of blockchain-based programs over traditional loyalty programs pertaining to usage, accrual, relevance, expiration, and transferability. We then apply expectancy theory to assess consumers’ perceptions in two empirical studies, both of which reveal an overall preference for blockchain-based loyalty programs over traditional models: an analysis of 5,059 Twitter tweets detects more positive feedback for the blockchain-based program, and a survey of 206 consumers reveals a significantly more positive attitude toward the blockchain-based loyalty program with respect to accrual, relevance, expiration, and transferability.

Excellent jujube supply-chain management is of great significance to the development of the Xinjiang jujube industry. However, traditional jujube supply-chain management is faced with the dilemmas of opaque connection of transaction flow and capital flow information, unreliable product traceability information, and jujube farmers' lack of bargaining power. In this research, we propose a jujube supply-chain-management framework based on blockchain. Hyperledger fabric is the distributed solution platform of this research. The current blockchain-based traceability framework for agri-food emphasizes the construction process and ignores the performance and characteristics of the framework. This research optimizes the blockchain-network-topology architecture and storage cost of writing data. This not only solves the traceability of jujube, but also fills the gap in previous research on the traceability framework. Moreover, transactions are innovatively divided into common transactions and private transactions. Private transactions have enhanced the bargaining power of jujube farmers. Through the analysis of benchmark tests, the effectiveness and feasibility of the framework are verified.
