Thema: Distributed Ledger Technology Processes

Abstract:

DLT offers new means to establish trust relationships within cooperative processes among enterprises and thereby enables the implementation of use cases with a lack of existing intermediaries. Prominent examples of use cases are financial applications, provenance tracking and identity management. All of them are contingent upon trust in business processes and require the maintained security of the distributed ledger, that strongly depends on the heterogeneity and robustness of the underlying ecosystem. Participants need to trust the security of the ecosystem and the trust must be maintained over time. Therefore, the distributed ledger technology is not a simple component, that can be easily integrated into an existing application unless the complex relationship between participants and their trust into the underlying ecosystem is considered early in the engineering process.

This thesis introduces a framework, that comprises a structured methodology and tooling as a means to support conventional software processes that allow software architects to address the specific requirements of distributed ledger applications. We argue that these subjects are important to ensure the quality and sustainability of an application, since 1) a distributed ledger, that is not capable of handling future requirements of a use case represents eventually a bottleneck and thus, harms the efficient and reliable execution of business processes, 2) smart contracts with software bugs, that either prevent the efficient execution of business processes or favor one party over another will erode the trust that participants have into the ecosystem, and 3) if the DLT is not capable of securing substantial amounts of data use cases, that rely on the processing of data are disadvantaged and the consequences for an ecosystem when handling large amounts of data in the future are unforeseeable.
