Recently, both the Internet of Things (IoT) and Blockchain have gained enormous adaptation and popularity in information-based systems. The inherent problem with IoT is security at each layer. Critics have often touted IoT as the Insecure Internet of Things (IIoT). Rapid growth can be seen in the requirement for designing a secure and robust model for performing regular tasks such as sensing data, processing of sensed data, storage of data or information, and mutual communication. The development of such a model, which involves conquering numerous stumbling blocks, is a little hard. Cybersecurity threats materialize every day, while older threats still linger and wait to be exploited once again. It is an unfortunate truth that IoT is also at risk from these cyber threats. The coupling of both technologies will help to create a robust infrastructure for smart things. Blockchain can be implemented at several levels, such as accessibility, automation, configuration, authentication and data protection. The salient advantages of depleting Blockchain technology in amalgamation with the IoT are constructing conviction, cutting costs, and acceleration in transactions. Secured and reliable IoT can be used in many commercial applications and industries, such as fintech, healthcare, manufacturing, supply chain management, etc. Many industry analysts are saying that Blockchain technology is proving to be a silver bullet for the IoT in terms of fears over security, privacy and reliability. Blockchain technology will not be the holy grail of cybersecurity, but it is a prevalent tool that can help to solidify IoT systems. Blockchain has shown countless prospects for technologies and systems based on IoT, where security issues are disrupting the centralized system with a single point of failure. The use of Blockchain technology in IoT can increase the security aspect and user access management mechanisms, which further leads to a robust mechanism. However, these two fields of IoT and Blockchain are relatively new, and a lot of research is going on in these fields. Moreover, the combination of these two technologies will come up with new challenges also. Therefore, there is a need to review the techniques that are already in place to carry out further scoping, so in this chapter, the researchers have tried to focus on the review of technologies germinating due to the coupling of the IoT with Blockchain technology. Some case studies based on the amalgamation of these two technologies are also discussed in this chapter. The security mechanism is based on three main factors: Confidentiality, Integrity and Availability. These factors have been considered when taking any research in this domain into consideration. Researchers have also proposed a model of the IoT integrated with Blockchain ledger for the dissemination of information with an abstract form of security. There are more than 20 techniques invented by various researchers that have been analyzed based on various attack vectors, and the corresponding reviews are discussed in detail. Ten main attacks are also discussed with respect to the 20 techniques used in the proposed coupled technology. As well as the security challenge, other challenges like scalability, storage, processing power, time complexity, the complexity of hybrid structure, the need for skilled manpower, and many other challenges are also discussed in this chapter. A consolidated review of the research carried out in the domain of various Blockchain-based IoT systems is also discussed in depth.

Blockchain technology and supply chains: The paradox of the atheoretical research discourse

In this technology era, the Internet of Things (IoT) plays predominant role in several aspects of real-life problem. The thrust area of IoT applications include smart city, smart transport, smart healthcare, smart environment, smart agriculture, etc. The IoT system involves heterogeneous sensors and devices at the edge layer of the protocol stack. These IoT devices are characterized in term of hardware specification, different communication protocols, services offered by these devices and trustable users of the IoT devices. Hence, the IoT requires efficient security and privacy mechanism for heterogeneous IoT devices and as well as voluminous amount of data generated by these IoT devices. Conventionally, the security for homogenous devices is provided by the centralized mechanism through authentication, encryption/decryption of data, digital signatures and cryptographic algorithms. However, IoT has characteristics of heterogeneous, autonomous and resource constraint IoT devices, in which case, the conventional centralized security solutions fail tremendously. Hence, the decentralized approach of Block chain is well suited for this scenario. This chapter targets to provide the comprehensive review of various security, privacy and access issues, solution approaches and challenges towards IoT. The role block chains in five different IoT applications are discussed in this chapter. These IoT applications include Intelligence Transport system, Smart Healthcare system, supply chain management, IoT ecosystem, Smart City. This chapter discusses how block chain provides security, smart contracts, access control and proof-of-work and proof-of-state are carried out at decentralized manner. The chapter presents the use case of block chain beyond crypto currency and bit coin, the data are to be preserved through block chain technique and different mining techniques used in block chain for these IoT applications.

This Chapter covers three interdisciplinary, observable, and rapidly developing areas of research, namely the Internet of Things (IoT) technologies, the blockchain (BC) technologies (BCT), and cybersecurity management for the IoT. The chapter is organized as follows: after a short introduction, the IoT technologies are discussed, including the IoT concept and definitions, generalized IoT architecture and reference model proposed, and the IoT standardization issues. The second part of the Chapter is devoted to the BCT and their application areas, as well as to a BC glossary worked by the authors and the list of standards for the BCT. On this basis, two main directions of applying the BCT to the IoT are represented, namely for designing BC-based secure IoT infrastructure and BC-based system for managing cybersecurity in the IoT. Final discussion and future research areas conclude the Chapter.

The article identifies the main challenges in supply chain management in 2023. Factors influencing the choice and application of Lean / Agile methodology were also analyzed, their differences were outlined, and a Lean / Agile matrix was constructed, which can be used in supply chain management depending on the characteristics of supply and demand. It is reasoned that as a result, it will enable organizations to optimize operations, reduce costs, improve quality and increase customer satisfaction in a dynamic and competitive business environment. It is also important to understand how lean thinking and the agility method can strengthen and optimize the efforts of business structures in the field of digital transformation. The future of logistics is expected to be shaped by various trends and developments. The key aspects that can determine the future of logistics and the specifics of supply chain management are characterized. The main of them are: automation and robotics; artificial intelligence and machine learning; Internet of Things (IoT); sustainable business practices and green logistics; blockchain technology; customer orientation. The expediency of future implementation of a combined (hybrid) supply chain management methodology ("LEAGILE strategy"), which is a combination of both lean and agile supply chain management, is asserted. Speaking of synergy, combining Lean and Agile methodologies in supply chains can lead to the best results by leveraging the strengths of both approaches. Lean focuses on eliminating waste and increasing efficiency, while Agile emphasizes flexibility and the ability to respond to customer demands. By integrating these two approaches, organizations can achieve a balance between cost reduction and customer satisfaction. Some ways to combine Lean and Agile in supply chains for best results are outlined: 1. Demand-driven manufacturing; 2. Cross-functional collaboration; 3. Continuous improvement; 4. Partnership with suppliers; 5. Technology integration; 6. Flexibility in production; 7. Customer-oriented approach. It is worth implementing a situational approach to choosing a supply chain management methodology in conditions of uncertainty, taking into account the nature of demand, the product life cycle, marketing goals, etc.

Blockchain technology as a means of sustainable development

Purpose: The purpose of this paper is to assess if blockchain technology, which is hailed for its potential to improve supply chain transparency and efficiency, can deliver to this promise (Abreu et al., 2021; Mahyuni et al., 2020; Manzoor et al., 2022; Rennie, 2022; Yiannas, 2018). Supply chains are increasingly complex and full transparency is difficult to achieve and may sometimes be undesired, yet governments worldwide are demanding more transparency especially with respect to the social and environmental sustainability of supply chains (Francisco & Swanson, 2018; Franke, 2021; Najjar, 2021). If blockchain technology allows to close this gap, without compromising corporate confidentiality and efficiency requirements, it might change supply chain management drastically. Most other research in this field remains rather superficial with respect to the fundamentals of blockchain technology and supply chain management. Our study will add to the very limited theoretically founded research on blockchain potentials in supply chains.Study Design: Our paper is conceptual. Based on the extant literature, we compare blockchain technology and its advantages to the characteristics of supply chains and challenges of supply chain management to identify a theoretical fit. We investigate if published case studies of blockchain technology in supply chain management support this. Finally, we devise a conceptual framework for the application of blockchain technology in supply chain management.Findings: There is, currently, very limited use for blockchain technology in supply chain management. It does not provide an answer to several of the challenges that exist in supply chain management. Blockchain technology was primarily devised as encryption technology for virtual entities and transactions involving them and not for tangible objects. Published case studies describing the use of blockchain technology in supply chain management do not contradict these findings.They rely on private blockchain solutions lacking the key benefits of blockchain technology. Our conceptual framework constitutes a reference for a future public blockchain solution for supply chains. It offers solutions for some of the challenges but also cannot solve some fundamental challenges, like power imbalances in supply chains.Limitations: Blockchain technology undergoes rapid development. Future blockchain technology may be faster, less energy-intensive and more integrated with other technologies. This may be aided by developments in hardware, like quantum computing. The findings of this paper are limited to currently available technology.Implications: Companies and governments alike should be very cautious when considering investing in currently available blockchain solutions for supply chain management.

Blockchain technology can be used to record real data at various nodes in the entire supply chain and can achieve timely data sharing and full traceability of the whole lifecycle of products in the supply chain. This study conducts a systematic literature review based on the WOS database, focusing on the research topic of the application of blockchain technology in supply chain management. We propose clear search and screening criteria based on 4 research questions and finally obtain 591 target studies. We conduct a detailed study on the distribution of the target literature in this research area, country/region, institution, and journal. Different countries/regions cooperate with each other and, thus, are clustered into five significant countries regions’ cooperation networks. There is a strong coupling relationship between research institutions, forming four major institutional cooperation networks. According to the analysis of those papers with a high number of citations, most of such papers were published in 2019, while the cross-citation phenomenon between papers occurred more frequently in 2021 and 2022. We use VOSviewer for visual coupling analysis of all keywords, which are automatically clustered into three research hotspots. Using CiteSpace to perform timeline-based keyword cooccurrence analysis, we find that scholars have gone through a “discovery-acceptance-question-improvement” process for the application of blockchain technology in supply chain management. According to the intensity and duration of burst detection words in different years, we draw three key points for future research. (i) Blockchain technology should be used to restructure and optimize the high-end food and medical cold chain supply chains. (ii) Blockchain technology should be used to enhance the cooperative relationship between supply chain members and the overall competitiveness of the supply chain. (iii) Innovate blockchain encryption technology that should be used to reduce the risk of information and privacy leakage in the supply chain.
