DECENTRALIZED BUSINESS PROCESS MODELING AND
INSTANCE TRACKING SECURED BY A BLOCKCHAIN
Härer, Felix, University of Bamberg, Bamberg, Germany, email@example.com
For supporting the conceptualization and the management of enterprise models in a decentralized
manner, this paper introduces an approach based on model versioning and blockchain technologies.
The main contribution is twofold, consisting of a., the creation of models for inter-organizational
business processes in a decentralized environment, and b., means for tracking process instances using
meta-data at run time. Models for business processes, workflows, and instance states are collaboratively created as part of a decentralized architecture. Based on this approach, a hierarchical versioning and modeling approach is employed in order to create and manage public and private models in a
transactional fashion. For forming relationships among decentralized participants, semi-formal models linked to a blockchain are suggested. The approach is evaluated with a supply chain use case and
demonstrated in an implemented modeling tool.
