Integration of ontologies with decentralized autonomous organizations development: A systematic literature review

This paper presents a systematic literature review of the integration of ontologies into the Decentralized Autonomous Organization (DAO) development process. The review extracted data from 34 primary studies dealing with ontologies in the blockchain domain. DAO has become a key concept for the development of blockchain-based decentralized software systems. DAOs are seen as a positive alternative for organizations interested in the adoption of decentralized, reliable and transparent governance, as well as attracting the interest of academic research. However, there is no common understanding or generally accepted formal definition of a DAO, and the guidelines that provide support for the adoption and development of DAOs are limited to a few key references that lack the computational semantics needed to enable their automated validation, simulation or execution. Thus, the objective of this paper is to provide an unbiased and up-to-date review related to the integration of ontologies within DAOs which helps to identify new research opportunities and take advantage of this integration from a blockchain-based decentralized perspective

Designing a Blockchain Model for the Paris Agreement’s Carbon Market Mechanism

This paper examines the benefits and constraints of applying blockchain technology for the Paris Agreement carbon market mechanism and develops a list of technical requirements and soft factors as selection criteria to test the feasibility of two different blockchain platforms. The carbon market mechanism, as outlined in Article 6.2 of the Paris Agreement, can accelerate climate action by enabling cooperation between national Parties. However, in the past, carbon markets were limited by several constraints. Our research investigates these constraints and translates them into selection criteria to design a blockchain platform to overcome these past limitations. The developed selection criteria and assumptions developed in this paper provide an orientation for blockchain assessments. Using the selection criteria, we examine the feasibility of two distinct blockchains, Ethereum and Hyperledger Fabric, for the specific use case of Article 6.2. These two blockchain systems represent contrary forms of design and governance; Ethereum constitutes a public and permissionless blockchain governance system, while Hyperledger Fabric represents a private and permissioned governance system. Our results show that both blockchain systems can address present carbon market constraints by enhancing market transparency, increasing process automation, and preventing double counting. The final selection and blockchain system implementation will first be possible, when the Article 6 negotiations are concluded, and governance preferences of national Parties are established. Our paper informs about the viability of different blockchain systems, offers insights into governance options, and provides a valuable framework for a concrete blockchain selection in the future.DFG, 414044773, Open Access Publizieren 2019 - 2020 / Technische Universität Berli

BlockNet Report: Exploring the Blockchain Skills Concept and Best Practice Use Cases

In order to explore the practical potential and needs of interdisciplinary knowledge and competence requirements of Blockchain technology, the project activity "Development of Interdisciplinary Blockchain Skills Concept" starts with the literature review identifying the state of the art of Blockchain in Supply Chain Management and Logistics, Business and Finance, as well as Computer Science and IT-Security. The project activity further explores the academic and industry landscape of existing initiatives in education which offer Blockchain courses. Moreover, job descriptions and adverts are analyzed in order to specify today's competence requirements from enterprises. To discuss and define the future required competence, expert workshops are organized to validate the findings by academic experts. Based on the research outcome and validation, an interdisciplinary approach for Blockchain competence is developed. A second part focuses on the development of the Blockchain Best Practices activity while conducting qualitative empirical research based on case studies with industry representatives. Therefore, company interviews, based on the theoretical basis of Output 1, explore existing Blockchain use cases in different sectors. Due to the interdisciplinary importance of Blockchain technology, these skills will be defined by different perspectives of Blockchain from across multiple mentioned disciplines. The use cases and companies for the interviews will be selected based on various sampling criteria to gain results valid for a broad scale. The analysis of the various use cases will be conducted and defined in a standardized format to identify the key drivers and competence requirements for Blockchain technology applications and their adoption. On the one hand, this approach ensures comparability, on the other hand, it facilitates the development of a structured and systematic framework.Comment: arXiv admin note: text overlap with arXiv:2102.0322

Tackling the Challenges of Information Security Incident Reporting: A Decentralized Approach

Information security incident under-reporting is unambiguously a business problem, as identified by a variety of sources, such as ENISA (2012), Symantec (2016), Newman (2018) and more. This research project identified the underlying issues that cause this problem and proposed a solution, in the form of an innovative artefact, which confronts a number of these issues. This research project was conducted according to the requirements of the Design Science Research Methodology (DSRM) by Peffers et al (2007). The research question set at the beginning of this research project, probed the feasible formation of an incident reporting solution, which would increase the motivational level of users towards the reporting of incidents, by utilizing the positive features offered by existing solutions, on one hand, but also by providing added value to the users, on the other. The comprehensive literature review chapter set the stage, and identified the reasons for incident underreporting, while also evaluating the existing solutions and determining their advantages and disadvantages. The objectives of the proposed artefact were then set, and the artefact was designed and developed. The output of this development endeavour is “IRDA”, the first decentralized incident reporting application (DApp), built on “Quorum”, a permissioned blockchain implementation of Ethereum. Its effectiveness was demonstrated, when six organizations accepted to use the developed artefact and performed a series of pre-defined actions, in order to confirm the platform’s intended functionality. The platform was also evaluated using Venable et al’s (2012) evaluation framework for DSR projects. This research project contributes to knowledge in various ways. It investigates blockchain and incident reporting, two domains which have not been extensively examined and the available literature is rather limited. Furthermore, it also identifies, compares, and evaluates the conventional, reporting platforms, available, up to date. In line with previous findings (e.g Humphrey, 2017), it also confirms the lack of standard taxonomies for information security incidents. This work also contributes by creating a functional, practical artefact in the blockchain domain, a domain where, according to Taylor et al (2019), most studies are either experimental proposals, or theoretical concepts, with limited practicality in solving real-world problems. Through the evaluation activity, and by conducting a series of non-parametric significance tests, it also suggests that IRDA can potentially increase the motivational level of users towards the reporting of incidents. This thesis describes an original attempt in utilizing the newly emergent blockchain technology, and its inherent characteristics, for addressing those concerns which actively contribute to the business problem. To the best of the researcher’s knowledge, there is currently no other solution offering similar benefits to users/organizations for incident reporting purposes. Through the accomplishment of this project’s pre-set objectives, the developed artefact provides a positive answer to the research question. The artefact, featuring increased anonymity, availability, immutability and transparency levels, as well as an overall lower cost, has the potential to increase the motivational level of organizations towards the reporting of incidents, thus improving the currently dismaying statistics of incident under-reporting. The structure of this document follows the flow of activities described in the DSRM by Peffers et al (2007), while also borrowing some elements out of the nominal structure of an empirical research process, including the literature review chapter, the description of the selected research methodology, as well as the “discussion and conclusion” chapter
