Blockchain as Middleware+
(2019)
In supporting decision making of manufacturing companies, the added value of cross-domain data exchange for aggregating information is well established in enterprise organization research and is represented, for example, in the reference model “Internet of Production” (IoP). Currently, there is little research regarding the role of Blockchain technology in such a reference model and how specifically the IoP needs to be expanded to address cross-company data exchange. This paper presents a proposal for such an extension to outline the use of Blockchain technology and to elaborate the open research demands for implementation. In particular, desk research and the development of concrete use cases for cross-company data exchange between business application systems were carried out. The results are, on the one hand, extending the IoP by a third dimension, which corresponds to the supply chain, and, on the other hand clarification of the role Blockchain technology can take in this context.
This paper won the John Burbidge Best Paper Award (see Attachment 2).
Company Data in the Blockchain: A Juxtaposition of Technological Drivers and Potential Applications
(2018)
In the presented paper, the technical possibilities of Blockchains are analyzed and classified according to their suitability to address specific challenges. This makes it possible to identify those technological drivers that are particularly promising for applicability in a corporate context. This includes, for example, tamper-resistance and security from forgery, which can be achieved without intermediaries with the help of data encryption methods using hash functions. Another technological capability of Blockchains is to provide a high degree of data security, which can be realized using public-key cryptography.
The technological drivers will be juxtaposed with data as typically generated in manufacturing companies (orders and order confirmations, production data, quality-related data, etc.). Subsequently, the prerequisites that these data must meet with regard to storage capacity and transferability will be identified. By linking the results to the identified technological drivers and functions it becomes possible to determine what types of company data have the potential to be successfully stored and managed in a Blockchain.
