In the last four years, the evolution and adoption of blockchain and, more generally, distributed ledger systems have shown the affirmation of many concepts and models with significant differences in system governance and suitable applications. This work aims to update the critical analysis of blockchain technologies carried out by our previous contribution to this journal, extending the focus to distributed ledger components and systems. Starting from the topical concept of decentralization, we introduce concepts and building blocks currently adopted in the available systems centering on their functional aspects and impact on possible applications. We present some conceptual framing tools helpful in the application context, and we will propose the concept of process authenticity, which we will discuss through two use cases: blockchain document dematerialization and e-voting.

In the last four years, the evolution and adoption of blockchain and, more generally, distributed ledger systems have shown the affirmation of many concepts and models with significant differences in system governance and suitable applications. This work aims to analyze distributed ledger technology (DLT) critically. Starting from the topical idea of decentralization, we introduce concepts and building blocks currently adopted in the available systems centering on their functional aspects and impact on possible applications. We present some conceptual framing tools helpful in the application context: a DLT reference architecture, off-chain and on-chain governance models, and classification of consensus protocols. Finally, we introduce the concept of process authenticity, reviewing tools and strategies for integrating DLT with the physical world and proposing a constructive scheme for the authentication of a physical resource through alphanumeric data.

The use of Distributed Ledger Technologies in the field of production optimizes various use cases. Within the framework of the research project “Blockchain Reallabor in the Rheinisches Revier”, five use cases were defined for production in the first year of the project. The confidence in and transparency of stored data, the elimination of central entities and automatic micropayments in real time are revolutionizing auditing, product and process monitoring and life cycle assessment. With the machine data marketplace for trading process data and the rental of machine capacities in the form of subscription, for example, a Distributed Ledger creates new business models.In North Rhine-Westphalia (NRW), the field of users (17 percent) is currently not highly developed in comparison to service providers, infrastructure providers and research alliances (83 percent). Nevertheless, there are some projects that usually contain the described use cases in a less complex way and thus confirm their validity. An analysis of the ecosystem Distributed Ledger Technologies in the Rheinisches Revier provides some insights into the actors involved. There is a trend towards large companies implementing Distributed Ledger Technology projects. It is not possible to make a technology or infrastructure recommendation based on the developed ecosystem, since the identified use cases are handled with different infrastructures depending on the project.Finally, it should be emphasized that the federal state of North Rhine-Westphalia can be considered a pioneer in Distributed Ledger Technologies in Germany. A nation-wide comparison of users from the manufacturing industry shows that over 65 percent are located in NRW. The establishment of the Distributed Ledger Technology in the small and medium business sector is, from today‘s point of view, the next step towards reaching the level of perfect productivity according to the Gartner hype cycle.

Abstract Insurance industry practitioners have deep knowledge of their industry, but there is a lack of a simple-to-understand, practical blueprint on applying distributed ledger technology solutions, including blockchain. This paper provides a practical guide for actuaries, risk professionals, insurance companies and their Boards on blockchain, including an education piece to provide an understanding of the technology. Examples of real-world applications and use cases in insurance are provided to illustrate the capability of the technology. The current risks and challenges in adopting the technology are also considered. Finally, a checklist of issues to consider in adopting a blockchain solution for insurance business problems is provided.

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.

Governance for centralized organizational structures has long roots and well-developed frameworks, including for various specialty areas, such as IT or data governance. However, the introduction of blockchain technology as a supportive tool for implementing decentralized organizations requires a renewed focus for research in the area. The paper utilizes empirical data from blockchain ecosystems in the form of white papers (public communique of intention) to analyze their governance intentions. The empirical findings are based on a review of 241 blockchains and distributed ledger technology white papers, out of which 67 include explicit descriptions of how governance should be organized in the ecosystem. Our empirical research distinguishes between three categories of governance: objectives, mechanisms, and stakeholders. We further identify 28 features for these categories, which are described in an open encoding format. Hence, the paper contributes to the emerging blockchain research field, particularly to the decentralized aspects of blockchain governance research. This research also reveals that blockchain governance does not receive the attention it should as a large majority of ecosystems have not disclosed their governance intentions. The results can be utilized as a framework for future research. The results can also be helpful for industry when designing and developing governance systems.
