The lack of transparency along global supply chains poses challenges in the areas of fraud, pollution, human rights abuses, and inefficiencies. In this context, the blockchain has the potential to offer an unprecedented level of transparency, with a shared and decentralized database in which immutable and encrypted copies of information are stored on every node of the network. Using a single case study methodology, this paper investigates how blockchain technology can improve and facilitate sustainable business models. The aim of this paper is to understand how blockchain technology can drive the development of sustainable business models. Recent studies show the importance of sustainability perspectives for business models. The study was conducted by applying the CAOS (“Characteristic, Ambience, Organization, Start-up”) model to a start-up operating in the agri-food sector, not yet institutionalized, called Devoleum. The results indicate that blockchain technology can increase sustainability through realizing the traceability, security, and non-manipulability of information, which are particularly useful in the agri-food sector. Furthermore, the absence of intermediaries in blockchain technology contributes to reducing transaction costs and the time required to consolidate relations between the company and the environment. The limitations of this study must be identified in that the company is operational but not yet incorporated.
Based on the diffusion of blockchain technology in the smart grid, this paper studies the framework and application of the blockchain technology in the smart grid, so as to combine the blockchain with the smart grid and establish a sustainable supply chain. However, the establishment of a sustainable supply chain is based on a layered theoretical framework. Not only should the framework take into account needless attributes and the relationship among various criteria and aspects but the application should also involve a balance of multiple stakeholders. For the above reasons, this paper uses a combination of Fuzzy-DEMATEL and ISM. The results show that (1) the hierarchical path of sustainable supply chain management of the smart grid under the blockchain starts from the social level, pays attention to system construction, grasps the technical standards, and defines the development goals of the power grid. (2) The development of green energy has become a new market growth point. (3) The control of the operation level becomes the focus of the smart grid. (4) The optimization and development of the economic structure are restricted by social factors. By integrating and optimizing the blockchain and supply chain, this paper puts forward a theoretical framework, establishes a sustainable GIP application system with multistakeholder participation at the supply chain level, and indicates the significance of the blockchain in the smart grid.

Nowadays, high expectations are set for a digitally enabled circular economy (CE), to enhance resource efficiency. Tracing, tracking, and storing information is most important for this. In this paper, the application of Internet of Things (IoT) and Distributed Ledger Technology (Blockchain) are hence discussed by presenting the case of professional Electrical and Electronic Equipment (EEE) in Italy. Within the context of CE, prevention of electronic waste (WEEE) is extremely relevant as it is a fast-growing waste stream, and the products contain environmentally damaging substances as well as valuable and rare materials. The use of a proper combination of IoT and blockchain can help the producers to keep control on products until EEE end-of-life, while promoting CE strategies and supporting decision-making. Based on the outcomes of five interviews conducted in 2019 to companies of the EEE sector, potential improvements in the EEE end-of-use management are discussed. After providing the definition of requirements for both the technical solution and its testing are provided, three solution variations and the related business models are created and presented, as well as considerations on their environmental and economic impacts. The study shows how digital technologies can support the appropriate and circular management of EEE products and WEEE.

Over the last few years, the increasing level of cyber risks derived from the growing connectedness of Industry 4.0 has led to the emergence of blockchain technology as a major innovation in supply chain cybersecurity. The main purpose of this study is to identify and rank the significant barriers affecting the implementation of blockchain technology as a key component of cyber supply chain risk management (CSCRM). This research relied on the “interpretive structural modeling (ISM)” technique in the structure of a hierarchical model to investigate the contextual relationships of identified challenges for blockchain adoption in CSCRM; it also classifies the influential challenges based on their driving and dependence powers. The results highlight that “cryptocurrency volatility” is the challenge at the top level of the hierarchy, implying weak driving power but it is strongly dependent on the other challenges. “Poor regulatory provisions”, “technology immaturity”, “dependent on input information from external oracles”, “scalability and bandwidth issues”, and “smart contract issues” are significant challenges for the adoption of blockchain in cyber supply chain risk management and are located at the bottom level of the hierarchy with higher driving power. The implications for theory and practice of the research are also highlighted.

Current research on smart contracts focuses on technical, conceptual, and legal aspects but neglects organizational requirements and sustainability impacts. We consider this a significant research gap and explore the relationship between smart contracts and sustainability in supply chains. First, we define the concept of smart contracts in terms of supply chain management. Then, we conduct a content analysis of the literature to explore the overlapping research fields of smart contracts and sustainability in supply chains. Next, we develop a semi-structured assessment framework to model the potential environmental and social impacts induced by smart contracts on supply chains. We propose a conceptual framework for supply chain maturity by mapping the relationships between organizational development, sustainability, and technology. We identify smart contracts as a foundational technology that enables efficient and transparent governance and collaborative self-coordination of human and non-human actors. Thus, we argue that smart contracts can contribute to the economic and social development of networked value chains and Society 5.0. To stimulate interdisciplinary research on smart contracts, we conclude the article by formulating research propositions and trade-offs for smart contracts in the context of technology development, business process and supply chain management, and sustainability.

Blockchain is an emerging technology with potential to address issues related to sustainability. Literature reviews on blockchain and sustain ability exist, but there is a need to consolidate existing results, in particular, in terms of Sustainable Development Goals (SDG). This extended abstract presents an ongoing tertiary study based on existing literature reviews to investigate the relationship between blockchain and sustain ability in terms of SDGs. Results from a pilot analysis of 18 reviews using thematic analysis are presented.
A claim can be understood as a negative result of the performance of a contract, as it is necessary to fulfill the obligation and/or indemnify (freight damage claim, for example). Today’s claims management faces a variety of problems, such as inefficient claims postings, possible data forgery, and a very lengthy claims resolution process. All these problems can be solved by using a synthesis of innovative tools, e.g., a blockchain system, game theory, and statistical methods. Theoretical possibilities and practical examples regarding solving claims management problems were identified by analyzing various scientific sources. However, it remained unclear whether these methods could interact with each other, complicate the existing claims settlement process or not, or whether a synthesis of such measures would be viable. Therefore, a qualitative study was conducted and answers to the above questions were found. The research revealed that 75% of international Lithuanian logistics companies can apply the synthesis of these methods in claims management and solutions. Using the concordance coefficient formula, the value of W was calculated. This coefficient indicated that the opinions of the experts who participated in the study were somewhat similar. The value of the actual χ2 distribution was also calculated. The result obtained shows that the experts’ opinions were somewhat harmonized and that their compatibility was not accidental. The use of blockchain system synthesis in combination with game theory and statistical methods could help international logistics companies to reduce their costs, speed up the management process, and increase data security and reliability while ensuring structured one-stop claims management.

The circular economy is gaining in importance globally and locally. The COVID-19 crisis, as an exceptional event, showed the limits and the fragility of supply chains, with circular economy practices as a potential solution during and post-COVID. Reverse logistics (RL) is an important dimension of the circular economy which allows management of economic, social, and environmental challenges. Transportation is needed for RL to effectively operate, but research study on this topic has been relatively limited. New digitalization opportunities can enhance transportation and RL, and therefore further enhance the circular economy. This paper proposes to review practical research and concerns at the nexus of transportation, RL, and blockchain as a digitalizing technology. The potential benefits of blockchain technology through example use cases on various aspects of RL and transportation activities are presented. This integration and applications are evaluated using various capability facets of blockchain technology, particularly as an immutable and reliable ledger, a tracking service, a smart contract utility, as marketplace support, and as tokenization and incentivization. We also briefly introduce the physical internet concept within this context. The physical internet paradigm proposed last decade, promises to also disrupt the blockchain, transportation, and RL nexus. We include potential research directions and managerial implications across the blockchain, transportation, and RL nexus.
Over the past decade, the blockchain technology has been actively embraced by an increasing number of companies. Blockchain has proven its effectiveness not only in the financial sector, but also in logistics and supply chain management, and has received extensive coverage in the scientific literature. At the same time, the implementation of blockchain in logistics and supply chain management (SCM) is technically difficult and requires significant financial costs. In this regard, its distribution in countries across the world is uneven. In this study, we compare the implementation of blockchain in countries with developed (Germany) and emerging (Russia) economies. Thus, our study provides new findings and information on the similarities and differences in blockchain implementation strategies in countries with developed and emerging economies. This comparative analysis reveals country peculiarities and different approaches regarding the application of blockchain technologies. The research methodology is based on the case study method. Three economic sectors are selected for the cross-country comparative analysis: the energy, food, and pharmaceutical industries. The analysis is focused on the use of blockchain along all three parts of the supply chain: upstream, production and downstream. Using theory building through case studies, our research results reveal many similarities in blockchain implementation in Germany and Russia. They show that blockchain is actively used in all three analyzed sectors by companies in both countries. Moreover, the technology proves its effectiveness in both upstream and downstream parts of the supply chain. In both Germany and Russia, blockchain is mainly used by large businesses due to its high costs. However, there are some differences regarding the implementation process of the technology in both countries. Firstly, the state support is required for some Russian blockchain projects. Secondly, none of the Russian companies has the necessary "full range" of blockchain competencies, so all Russian projects are carried out in collaboration with other parties, primarily IT partners. Thirdly, most of the Russian blockchain projects are still local in nature and relate to the use of technology in the relationship between the specific supplier and corresponding consumers.
Purpose The purpose of this paper is to contribute to the debate on blockchain (BC) adoption for preventing counterfeiting by investigating BC systems where different options for BC feeding and reading complement the use of BC technology. By grounding on the situational crime prevention, this study analyses how BC systems can be designed to effectively prevent counterfeiting. Design/methodology/approach This is a multiple-case study of five Italian wine companies using BC to prevent counterfeiting. Findings This study finds that the desired level of upstream/downstream counterfeiting protection that a brand owner intends to guarantee to customers through BC is the key driver to consider in the design of BC systems. The study identifies which variables are relevant to the design of feeding and reading processes and explains how such variables can be modulated in accordance with the desired level of counterfeiting protection. Research limitations/implications The cases investigated are Italian companies within the wine sector, and the BC projects analysed are in the pilot phase. Practical implications The study provides practical suggestions to address the design of BC systems by identifying a set of key variables and explaining how to properly modulate them to face upstream/downstream counterfeiting. Originality/value This research applies a new perspective based on the situational crime prevention approach in studying how companies can design BC systems to effectively prevent counterfeiting. It explains how feeding and reading process options can be configured in BC systems to assure different degrees of counterfeiting protection.
Purpose This paper aims to examine and overcome the barriers to the widespread adoption of blockchain technology, introducing a novel concept of sustainability in the fashion supply chain. Design/methodology/approach This work is an exploratory study of a well-known fashion company operating in the Veneto region (Italy). Data extracted from interviews and focus groups are coded using the (CAQDAS) software AQUAD. The outcome is then organized according to an adapted TOE view. Findings This exploration study's findings support the idea that the blockchain solution could be a valuable add-on in sustainable supply chains. However, a high understanding of technology and extensive communication with clients is required for successful integration. Research limitations/implications Being the outcome of qualitative analysis, the findings require further investigation to be inferable at a broader scale. As the project is still incomplete, some managerial choices are always subject to change. Practical implications Focused on a practitioner approach, this paper should guide managers in the process of successfully implementing blockchain technology. Arguably, similar companies may opt for similar choices. Originality/value To the best of the authors' knowledge, this is the first paper to contextualize and address the blockchain adoption barriers in the fashion supply chain. Furthermore, it offers an overview of how blockchain affects sustainable production.
Traditional business models involve cost, market development, distribution channels, business partnerships, and supply chain management. The development of the digital economy and digital network technology has engendered a shift away from the traditional model of operation. Intermediaries have long played an essential role in promoting the benefits of economic activities, but new technology is increasingly replacing intermediaries in their roles of connecting players, such as, involving, committing, and mobilizing players. Potential conflicts of interest must therefore be further resolved, avoided, or mitigated. Blockchain technology, as a tool for keeping immutable and digital records, can address increasingly complex issues in global value chains to pursue sustainable development. It attempts to realize the trust mechanism and has been redefining the function of intermediaries. This study used a multiple-case study approach to examine how blockchain technology affects intermediate functionality. We evaluated the industry’s use of blockchains to assess how the processes were reshaped and how the intermediary roles were refined. On the basis of the findings, we propose three potential changes for the roles of intermediaries to improve operational efficiency.

Planning to adopt the Blockchain is very active in many industries, especially in supply chains. Researchers believe that the Radio-frequency identification (RFIDs), yesterday’s Blockchain, is now obsolete. The strongest reason that the Blockchain is the tool of this era is its unique features; real-time information sharing, cyber-security, transparency, reliability, traceability, and visibility, all of which boost the supply-chain performance. Despite the extensive literature on Blockchain, in recent years, no clear framework has defined whether a supply chain should implement Blockchain or not. This study attempts to fill this gap by proposing a framework for complex supply chain networks. In doing so, first, we identified the supply-chain practices of the oil industry in Pakistan, then we empirically analyzed the impact of these practices on operational performance. The results show that the supply chain management (SCM) practices positively impact operational performance. On the other hand, with the help of literature, we identified different Blockchain features and their influence on different supply chain practices. This study guides managers and decision-makers to evaluate their current supply-chain practices and understand the relationship between supply-chain practices and Blockchain features, and how different Blockchain features can help improving supply-chain practices and ultimately improving operational performance.

The purpose of this review is to describe the landscape of scientific literature enriched by an author’s keyword analysis to develop and test blockchain’s capabilities for enhancing supply chain resilience in times of increased risk and uncertainty. This review adopts a dynamic quantitative bibliometric method called systematic literature network analysis (SLNA) to extract and analyze the papers. The procedure consists of two methods: a systematic literature review (SLR) and bibliometric network analysis (BNA). This paper provides an important contribution to the literature in applying blockchain as a key component of cyber supply chain risk management (CSRM), manage and predict disruption risks that lead to resilience and robustness of the supply chain. This systematic review also sheds light on different research areas such as the potential of blockchain for privacy and security challenges, security of smart contracts, monitoring counterfeiting, and traceability database systems to ensure food safety and security.
Intelligent transformation of manufacturers requires smart logistics transformation collaboration, which improves competitiveness. In this study, we construct a Stackelberg game model based on the mutual influence and restriction in the relationship between a manufacturer and a logistics service provider (LSP) undergoing smart logistics transformation. We investigate whether cost-sharing (CS) or revenue-sharing (RS) contracts can coordinate the supply chain and suggest a hybrid CS–RS contract to improve performance. We find that, compared with decentralized options, CS and RS contracts achieve a higher level of smart logistics transformation. While the coordination and effectiveness of CS contracts are superior to those of RS contracts, neither can fully coordinate the supply chain. The proposed hybrid CS–RS contract allows the manufacturer to share the LSP’s costs before the transformation and its partial revenue after transformation, so that the LSP can reduce its service charge, thereby achieving full supply chain coordination.
Improving supply chain sustainability is an essential part of achieving the UN’s sustainable goals. Digitalization, such as blockchain technology, shows the potential to reshape supply chain management. Using distributed ledger technology, the blockchain platform provides a digital system and database to record the transactions along the supply chain. This decentralized database of transactions brings transparency, reliability, traceability, and efficiency to the supply chain management. This paper focuses on such novel blockchain-based supply chain management and its sustainability performances in the areas of environmental protection, social equity, and governance efficiency. Using a systematic literature review and two case studies, we evaluate whether the three sustainability indicators can be improved indirectly along supply chains based on blockchain technology. Our study shows that blockchain technology has the potential to improve supply chain sustainability performance, and we expect blockchain technology to rise in popularity in supply chain management.
The purpose of this research is to examine the green supply chain (GSC) financing decisions of manufacturers and capital-constrained retailers in order to establish a Stackelberg game model under decentralized and centralized decision-making. This paper studies the influence of retailers’ choice of trade credit or bank loan financing strategy on a GSC’s performance and analyzes their decision-making tendency. The results show that manufacturers should provide trade credit and participate in retailers’ financing decisions to avoid double marginal effects under both centralized and decentralized decision-making. Interestingly, the optimal value of green marketing effort and retailer order quantity was twice as high as the decentralized under the centralized decision, indicating that the centralized decision could better improve GSC’s financing efficiency. Especially when the trade credit financing strategy is feasible, this effect is more significant. Finally, the outcomes are verified through numerical simulation, which references GSC practitioners in management decisions.

The agricultural industry is highly underdeveloped and requires transformation in technology for food safety and reliability. A digital world is relying on blockchain technology for the successful implementation of sustainable e-agricultural supply chain management (e-Agri-SCM). In current advancements of blockchain in digital marketing, product website design (web design) is essential to streamline the requirements of the customer and the expectations of supply chain partners. The current research has incorporated the blockchain effect by web design elements into the agricultural supply chain management (Agri-SCM) study. In addition, partners in the digital marketing supply chain (DM-SCM) are also facing issues to identify significant web design elements-based blockchain technology to gain maximum profit. Therefore, a cooperative (Co-op) sustainable e-agricultural SCM model is developed in this study by considering the web design index and variable demand to decide shipments, selling price, cycle time, and advertisement cost for agriculture products. The uncertainties in the model due to intangible web design elements and basic costs are dealt with by the application of the fuzzy system whereas carbon emission is also considered for providing cleaner production. A real-time application of the proposed model is done by undertaking five different cases based on mutual share, demand curve, and advertisement budget among participants. The sensitivity analysis is also performed to identify important factors of the total profit. Findings of this work include significant web design elements (WDEs) i.e., web graphics, search engine optimization, cyber-security, fast loading, and navigation, as essentials for digital marketing to convince customers towards the product in a global SCM. The numerical results and managerial insights are advantageous for managers to get maximum profit by cooperative and digital marketing strategies to attain e-Agri-SCM.

This paper aims to examine the role of blockchain technology for the circular economy to enhance organisational performance in the context of China–Pakistan-Economic-Corridor (CPEC). A close-ended questionnaire-based survey of manufacturing firms was administered to collect cross-sectional data from 290 respondents, which has been analysed through structural equation modelling. The circular economy approach in supply chain management offers environmental as well as economic benefits to the organisations. With the beginning of the Industry 4.0 era, there is an emphasis on technology in every field. A relatively recent phenomenon of blockchain technology promises lots of potential improvement in business operations. According to our results, with features such as visibility, transparency, relationship management, and smart contracting, blockchain technology was found to play a positive role in the circular economy. Furthermore, green practices were found to have a positive nexus with environmental and economic pathways to the firms’ performance, whereas environmental performance was also found to have a positive nexus with the economic health of the firm. Last but not the least, both environmental and economic performances were found to be the cause of a boost in organisational performance.
Purpose The paper aims to present a systematic literature review (SLR) showing the benefits, challenges and future research of blockchain technology (BT) for the supply chain (SC), also suggesting how the features of BT can change the organizational aspects of the SC. Design/methodology/approach An SLR has been conducted to detect papers that contained the word “Blockchain” in their titles, keywords or abstracts. Consequently, a second filter to analyze BT papers for the SC was applied. Findings This paper shows through 31 variables classified into positive, negative and future directions of technology for the SC. For instance, BT will reduce time consuming of operations management and payments using smart contracts. In addition, integrating BT with other technologies will allow product tracking and sustainable production management. Research limitations/implications The selection of papers is limited to Scopus database and specifically to the Management Journal . Practical implications BT creates collaborative peer-to-peer and business-to-business markets. The technology automates several tasks such as order management, payment for goods, waste reduction and process control. Therefore, its use within the SCs will improve the productivity and profits of the participants. Originality/value This paper is focused on BT for the SC area with 60 articles analyzed. In addition, 13 variables on benefits, eight variables on challenges and 12 points on future research directions were analyzed. This work will help researchers and entrepreneurs to deepen about the changes that BT offers in SC.
