“…Despite the informality witnessed in the present study, several other studies have in contrast noted formality (Colicchia et al , 2019; Wang et al , 2019). The proposed application of BT according to the flow of the distributor's processes confirms the possibility of smart contracts being applied since they control the flow of transactions at each stage of the processes (Dolgui et al , 2020; Zhang, 2019). The formalization of the smart contract in the case studied, incorporating the validation of qualifiers, can be seen as an instrument capable of mitigating many risks.…”

“…In logistics operations, smart contracts control the flow of transactions at each stage. Warehouses can optimize capacity and shipments in real time, and carriers can provide cargo status and visibility to participants (Dolgui et al , 2020; Zhang, 2019). The application of a smart contract, converted into codes, stored and replicated in the computer system and supervised by the blockchain network, becomes an essential ally in risk mitigation (Min, 2019).…”

PurposeConsidering the importance of a safe food chain for consumers and the advent of blockchain technology (BT), this research studies a food service (FS) distributor. The research aims to understand the implications related to the functional processes of distribution in FS in which it would be possible to use blockchain to achieve agility, transparency of information and improvements in food safety.Design/methodology/approachFirstly, theory regarding blockchain technology in the supply chain (BT-SC) and FS was analyzed to contextualize the theme conceptually. A single case study including 11 supply chain companies was applied in a BT implementation study in an FS distributor.FindingsInvestment in infrastructure is often identified as a barrier to adoption of BT-SC. This was, however, not found in this case. Furthermore, the validation of users was only necessary for those parties directly participating in the process or information input. Finally, findings differentiate between qualifying criteria and operational processes when considering BT projects in FS.Research limitations/implicationsThe findings are restricted to this single case that provided an in-depth understanding of the topic. Statistical generalization is not possible at this stage of the research.Practical implicationsThe study is a practical example and can provide several insights to anyone looking to implement BT in their SC.Social implicationsThe social importance of the study lies in the importance of FS in the food sector, and by presenting ways that contribute to mitigating risks to consumers.Originality/valueReal-life cases of application of BT-SC illustrate its functionalities in operational processes.

“…According to report on ''Supply Chain Trends Recap'' by Eye for Transport in 2017, more than 60% of the SCM vendors are using BC technology for ensuring timeliness and validation in the overall delivery cycle [70]. Due to the formation of the tamper-proof chain, transactions and business procedures of blockchain technology, it is more secured and immutable.…”

Modern industry 4.0 applications are shifting towards decentralized automation of computing and cyber-physical systems (CPS), which necessitates building a robust, secure, and efficient system that performs complex interactions with other physical processes. To handle complex interactions in CPS, trust and consensus among various stakeholders is a prime concern. In a similar direction, consensus algorithms in blockchain have evolved over the years that focus on building smart, robust, and secure CPS. Thus, it is imperative to understand the key components, functional characteristics, and architecture of different consensus algorithms used in CPS. Many consensus algorithms exist in the literature with a specified set of functionalities, performance, and computing services. Motivated from these facts, in this survey, we present a comprehensive analysis of existing state-of-the-art consensus mechanisms and highlight their strength and weaknesses in decentralized CPS applications. In the first part, we present the scope of the proposed survey and identify gaps in the existing surveys. Secondly, we present the review method and objectives of the proposed survey based on research questions that address the gaps in existing studies. Then, we present a solution taxonomy of decentralized consensus mechanisms for various CPS applications. Then, open issues and challenges are also discussed in deploying various consensus mechanisms in the CPS with their merits and demerits. The proposed survey will act as a road-map for blockchain developers and researchers to evaluate and design future consensus mechanisms, which helps to build an efficient CPS for industry 4.0 stakeholders.

“…If the smart contracts are utilized in the framework of the blockchain, then the network can be highly secure and autonomous. The works of blockchain assist the supply chain in taking responsibility through the intelligent contracts, thereby easily producing a trustworthy re-establishing trade and circulating products [25]. 3-Healthcare System: Blockchain technology aims to ensure patient safety and data protection in the public ledger environment.…”

The year 2020 has shown the quick spread and devastating effect of Coronavirus (COVID-19) on the world economy, health, and human life. Combating the COVID-19 pandemic is crucial. Blockchain technology can assist in the fight against the COVID-19 pandemic by assuring safe and reliable medical supplies, accurate identification of virus hot spots, and establishing data provenance to verify genuine personal protective equipment that is decentralized, reliable, traceable, and transparent. A major proportion of current healthcare systems are centralized and are short on privacy and information necessary for the detection of fraud connected to the certification by the COVID-19 vaccine. The quick vaccination rollout and the deployment of a global vaccination campaign are crucial and dependent on the availability of transparent and operational distribution chains, which may be audited by all the necessary parties. Blockchain technology might also be used to assure transparent monitoring, storage, and distribution of COVID19 vaccinations. Smart contracts are built for monitoring and tracking the proper circumstances of vaccine distribution in comparison to safe handling of vaccine producers, informing all network peers. This study aims to investigate the effectiveness of block chain and smart contracts in the health care system. The article presents a model of the decentralized infrastructure of the health care system. The blockchain and intelligent contract technology provided has shown promising results. The proposed solution is economically feasible and ensures data integrity, security, transparency, and traceability. Future work aims to expand the functionalities of smart contracts and the blockchain technology.
