Blockchain technology is probably the most attractive innovation since the emergence of the internet. Blockchain refers to an open distributed ledger spread across multiple computers that hold digitally recorded transactions in a much more efficient, transparent, and secure manner. A blockchain consists of a number of blocks, each containing data relating to digital assets and a hash header that links it to the previous block in the chain. The blocks are linked together, and new blocks can be added and removed, following a process of consensus. Also, those involved in the transactions can share the distributed digital ledger without needing a centralized intermediary. This chapter aims to introduce blockchain technology and discuss the use cases and initiatives in various sectors of the society, in particular within the blockchain product vendors and service providers. Characteristics, benefits, types, underlying technologies, and platforms are also discussed for the sake of completeness.

A Chain

Blockchain, also known as a distributed ledger technology, stores different transactions/operations in a chain of blocks in a distributed manner without needing a trusted third-party. Blockchain is proven to be immutable, which helps with integrity and accountability, and, to some extent, confidentiality through a pair of public and private keys. Blockchain has been in the spotlight after successful boom of the Bitcoin. There have been efforts to leverage salient features of Blockchain for different applications and use cases. This paper presents a comprehensive survey of applications and use cases of Blockchain technology for making smart systems secure and trustworthy. Specifically, readers of this paper can have thorough understanding of applications and use cases of Blockchain technology.

The presented study addresses the current problems in the implementation of the distributed ledger (blockchain) technology in supply chain management mechanisms in the context of the digital economy. Aim. The study aims to analyze the application of the blockchain technology in modern economic processes from the perspective of logistics.Tasks. The authors consider the possibility of using the blockchain technology in the supply chain management system and explore ways to use the findings of the Eurasian Economic Commission (EEC) in the fieldof digital economy to organize information standardization processes within the supply chains of foreign and mutual trade.Methods. This study uses general scientific methods of cognition to examine approaches to the implementation of the blockchain technology in transport and logistics processes and to find opportunities for the implementation of smart contracts to ensure the traceability of the entire chain of commodity and information fl ws.Results. Implementation of the distributed ledger (blockchain) technology in the logistics processes of foreign and mutual trade increases the transparency of information fl ws and the speed of decisionmaking. This technology would allow the parties to negotiate directly, minimizing potential risks and the time required to approve a supply deal.Conclusions. The authors consider the possibility of using a systematic approach to the digitalization of transport and logistics processes and the subsequent standardization of information interaction at the B2B, B2G, and G2G levels, segmented by separate fields of transport and foreign trade and individual economic sectors. As a conclusion, the study assesses the prospects of the practical implementation of blockchain mechanisms in the creation of industrial platforms — digital platforms that provide integrated services for businesses and the government using a single window system.

And Control

Newly emerging cryptocurrencies and blockchain technology present a challenging research problem in the field of digital politics and economics. Bitcoin—the first widely implemented cryptocurrency and blockchain architecture—seemingly separates itself from the existing territorial boundedness of nation-state money via a process of algorithmic decentralisation. Proponents declare that the utilisation of cryptography to advance financial transactions will disrupt the modern centralised structures by which capitalist economies are currently organised: corporations, governments, commercial banks, and central banks. Allegedly, software can create a more stable and democratic global economy; a world free from hierarchy and control. In Money Code Space, Jack Parkin debunks these utopian claims by approaching distributed ledger technologies as a spatial and social problem where power forms unevenly across their networks. First-hand accounts of online communities, open-source software governance, infrastructural hardware operations, and Silicon Valley start-up culture are used to ground understandings of cryptocurrencies in the “real world.” Consequently, Parkin demonstrates how Bitcoin and other blockchains are produced across a multitude of tessellated spaces from which certain stakeholders exercise considerable amounts of power over their networks. While money, code, and space are certainly transformed by distributed ledgers, algorithmic decentralisation is rendered inherently paradoxical because it is predicated upon centralised actors, practices, and forces.

The Way

PurposeThis paper discusses how the features of blockchain technology impact supply chain transparency through the lens of the information security triad (confidentiality, integrity and availability). Ultimately, propositions are developed to encourage future research in supply chain applications of blockchain technology.Design/methodology/approachPropositions are developed based on a synthesis of the information security and supply chain transparency literature. Findings from text mining of Twitter data and a discussion of three major blockchain use cases support the development of the propositions.FindingsThe authors note that confidentiality limits supply chain transparency, which causes tension between transparency and security. Integrity and availability promote supply chain transparency. Blockchain features can preserve security and increase transparency at the same time, despite the tension between confidentiality and transparency.Research limitations/implicationsThe research was conducted at a time when most blockchain applications were still in pilot stages. The propositions developed should therefore be revisited as blockchain applications become more widely adopted and mature.Originality/valueThis study is among the first to examine the way blockchain technology eases the tension between supply chain transparency and security. Unlike other studies that have suggested only positive impacts of blockchain technology on transparency, this study demonstrates that blockchain features can influence transparency both positively and negatively.

This article describes the “Blockchain” which is an upcoming technology in the current leading world and which serves as a capital market use-cases for many of the global Fintech industries across the world, is a distributed ledger of economic transactions which not only used for recording financial transactions but mostly everything of value in this world. In the current world, mostly all the transactions are done through online which mainly includes the bank as a “middle man,” which could be untrustworthy at times. Blockchain comes into the picture which eliminates the need of a middle man or third party between the users who are involved in the transactions. Represents a financial ledger entry of data structure which consists of record of transactions which is digitally signed and cannot be tampered as authenticity is ensured in which the ledger is considered to be of high integrity. One of the leading and highly valued platform of blockchain is “Hyperledger Fabric” which is meant for securing transactions and serves a powerful container technology for smart contract development in the global capital firms. The potential of Blockchain and DLT in capital markets in this upcoming world could remove many of the inefficiencies and costs inherent in the global capital markets across the world and could be considered as a viable technology which enable to settlement.

Silver Bullet

There has been an increasing interest in blockchain technology from the health care sector in the last couple of years. The value proposition for using blockchain technology in the health care sector is to share sensitive patient data among health care entities securely and to empower patients. Blockchain technology allows patients to have an active role in developing and updating their own patient data. However, is blockchain technology really the silver bullet it seems to be? With this paper, we aim to understand the benefits and challenges of blockchain technology in the health care sector. We discuss innovation and security implications concerning blockchain technology in health care. Furthermore, we show that there is a need for more use cases to ensure the secure sharing of data within the health care sector. In our opinion, blockchain technology will not solve the issues encountered by the health care sector; in fact, it may raise more issues than it will solve.
