Construction customers want more complex facilities delivered faster and at a lower cost. Transaction costs account for a significant proportion of each new or refurbished facility (a 2017 report from the Infrastructure Client Group in the UK suggests as high as 50%), yet they contribute no value to the customer. Blockchain is being suggested as a way to reduce transaction costs by eliminating the need for intermediaries to build trust as a prerequisite for successfully executed agreements. This study first describes the thinking that underpins blockchain technology, outlining how it works, and the potential limitations of the technology. Second, using a case study, reviews the potential cost savings from the use of blockchain for a real estate company. The results reveal a potential cost savings from blockchain deployment at 8.3% of the total cost of residential construction, with a standard deviation of 1.26%. Third, we explore the implications, risks and applications of blockchain technology for improving flow in the end-to-end design and construction process and we identify opportunities for future research on blockchain applications in construction.

In the current era, blockchain based system getting a lot of attention across different industries especially in the domain of supply chain because of its streamlined nature at the same time keep the privacy intact as well as more efficient than the conventional system. However the traditional supply chain faced lot of challenges these days because of the complex networks. Blockchain integrated with IoT framework has the potential to overcome the challenges faced by the conventional systems across industries. Basically the IoT integrated blockchain system provides enough benefits such as connecting the link between the flows in the supply chain to improve the efficiency of the supply chain network, makes the system transparent that can reduce the code of conduct violation throughout the supply chain networks, the immutable properties helps the stakeholders to trace the products throughout the networks. Even though blockchain based system provides enough benefits across industries, so far the implementation rate is very low because of the lack of knowledge about the benefits of blockchain system as well as lack of understanding about how and why it is needed in their fields. In this paper we will highlight the difference between the conventional supply chain as well as blockchain based supply chain and the benefits of implementing blockchain in different sectors such as automotive, pharmaceutical, food industry, retail. This article will highlights the problems currently facing by the above mentioned industries by using the conventional supply chain as well as the solutions to the problems provide the blockchain based systems in those industries. This articles helps the people across sectors to understand the benefits of the blockchain based system in their respect fields as well as implement it to improve the efficiency of the overall system.
Despite key advances in healthcare informatics and management, little progress to address supply chain process-related problems has been made to date. Specifically, key healthcare supply chain processes include product recalls, monitoring of product supply shortages, expiration, and counterfeits. Implementing and executing these processes in a trusted, secure, efficient, globally accessible and traceable manner is challenging due to the fragmented nature of the healthcare supply chain, which is prone to systemic errors and redundant efforts that may compromise patient safety and impact health outcomes adversely. Blockchain, combined with the Internet of things (IoT), is an emerging technology that can offer a practical solution to these challenges. Accordingly, IoT blockchain offers a superior way to track and trace products via a peer-to-peer distributed, secure, and shared ledger of the blockchain network. This article highlights key challenges related to healthcare supply chains, and illustrates how IoT blockchain technologies can play a role in overcoming these challenges now and in the near future.

Blockchain technology is a revolutionary technology for its potential to build systems where strangers can transact with each other without the need of any intermediary to oversee the transaction between the parties. In our traditional degree certificate system, employers need to trust the intermediaries e.g. certificate holder, teacher and university officials for the legitimacy of the certificate. Because of trust, there are vulnerabilities to fraudulent activities by the intermediaries to produce fake diplomas or fake degree certificates. Fake certificates cause significant damages to the society. In this research, using design science research methodology (DSRM) process model, we have developed a conceptual model of a blockchain-based certificate system where blockchain technology replaces the need of trust on intermediaries in the certificate system and prevent the fraudulent activities to produce fake or illegitimate certificates. Our conceptual model addresses the fraudulent activities which are not addressed by the existing blockchain-based certificate systems. Developed artefact the conceptual model can be used for developing prototype and further research. This research also contributes to the research field of blockchain technology as a trust-free technology and fraud activities in degree certificate system.

This will lead GCC to a solid economic base. Blockchain technology can be applicable in many different fields such as Banking, education, Health, finance, government and trade. This article will address the literature review and methodology of Blockchain technology and innovation at the GCC, particularly in Saudi Arabia. Also, more research can be conducted in the future as the system may be integrated in these countries.
This paper presents a framework for traceable and transparent supply chain management (SCM) system for the agri-food sector using blockchain technology in Malaysia. Numerous researchers believed that the current SCM system consists of several weak points, especially when multiple enterprise resource planning (ERP) system utilizing centralized SCM. Thus, data transparency and traceability are limited. This study hypothesized that if blockchain technology correlates with transparency and traceability of SCM, the above limitation can be minimized, as blockchain technology works in a distributed manner. This research uses “pepper” as an agri-food domain. The research also recommends that permissioned blockchain is a better fit as compared to permissionless blockchain.

How to keep customers motivated in participative behaviors remains one major challenge in extant loyalty program (LP) studies. While some companies have initiated efforts to utilize blockchain-based distributed ledgers and smart contract capabilities to enhance customer experience and improve LP efficiencies, academic assessment of blockchain application in the LP context remains scarce. This research attempts to establish a theoretical overview of how the key natures of blockchain influence customers’ varying motivations (economy, autonomy, competence and relatedness) and perceived value, which consequently induce participative behaviors in a loyalty points context. Then, using an exploratory case study of Bubichain in China, we verify that the blockchain-enabled loyalty points scheme not only improves customers’ economic perceived value by meeting their economic motives, as the traditional one does, but also enhances their social interaction and psychological self-fulfillment value perception by meeting their intrinsic motivations, thus increasing customers’ experience and participation behaviors.
