Improving current supply chains by using distributed ledger technology (DLT) has been a highly researched topic during the last years. Currently, there are numerous articles elaborating on how such technologies can theoretically improve supply chains. However, case studies of such concepts and their economic value are scarce. In order to bridge this gap, we collaborated with a regional label company to clarify how a distributed ledger technology would benefit their ecosystem. This work answers the question of how such a prototype would look and whether it adds value. By following design science research practices, we design two artifacts based on requirements gathered in 14 interviews and discuss the artifacts’ elements within an evaluation panel. Our findings show that a distributed ledger application for the regional label ecosystem should have an open and decentralized architecture giving all participants full access to the shared data while still providing security and privacy for sensitive data. Additionally, data capturing should be simple. However, such an application does not add sufficient economic value and is currently of no practical interest in the regional label ecosystem as the expenditure likely exceeds the benefit.

This study covers the evolutionary development of block-chain technologies over the last 11 years (2009 — 2019) and sheds lights on potential areas of innovation in heretofore unexplored sub-components. For this purpose, we collected and analysed detailed data on 107 different block-chain technologies and studied their component-wise technological evolution. The diversity of their designs was captured by deconstructing the block-chains using the Tasca-Tessone taxonomy (2019) to build what we call the "tree of block-chain" composed of block-chain main and sub-components. With the support of information theory and phylogenetics, we found that most design explorations have been conducted within the components in the areas of consensus mechanisms and cryptographic primitives. We also show that some sub-components like {Consensus Immutability and Failure Tolerance}, {Access and Control layer} and {Access Supply Management} have predictive power over other sub-components. We finally found that few dominant design models - the genetic driving clusters of Bitcoin, Ethereum and XRP - influenced the evolutionary paths of most of the succeeding block-chains.

Whether or not blockchain technology adds value to supply chains is a highly controversial topic. It has been lauded as the technology that brings transparency and efficiency to supply chains. However, others find this view overly optimistic. In this paper, we aim to add more insight into the issue by applying an action design research approach. We develop and evaluate two artifacts in collaboration with companies and use the results to conclude how blockchain technology can help overcome issues in the current supply chain information flow. It shows that blockchains can provide a shared trust base and a common standard that allows for increased information exchange between supply chain partners. Based on our findings, we propose a research agenda for studying blockchain technology with a stronger focus on governance mechanism and transparency issues.

Die Integration innerhalb der Supply Chain gilt als wichtiger Erfolgsfaktor für Unternehmen, wobei insbesondere der digitale Informationsaustausch mit den Supply Chain Partnern eine zentrale Rolle spielt. Allerdings wird der Informationsfluss zwischen Unternehmen oft durch fehlendes Vertrauen und mangelnde technologische und finanzielle Ressourcen beeinträchtigt. Eine Möglichkeit, diese Hürden abzubauen, stellt die Blockchain-Technologie (BCT) dar. Diese Arbeit zeigt auf, dass mit der BCT eine gemeinsame Vertrauensplattform für den Informationsaustausch geschafft werden kann und die für den Unterhalt benötigten Ressourcen unter den Partnern aufgeteilt werden können. Am Fallbeispiel von Modum wird dargelegt, wie Blockchain-Startups den Zugang zur BCT für KMUs erleichtern können.
