AB This contribution evaluates the feasibility of blockchain technology for processes of a cyber-physical production system (CPPS) using a decision framework. The evaluation is based on an implemented CPPS use case. Opportunities for the use of smart contracts are identified and two exemplary smart contracts are designed. To integrate the heterogeneous and resource-constrained IoT devices of a CPPS, three levels of connection to the blockchain are identified and applied to the use case. This work contributes to the implementation of an extensive blockchain-based CPPS.
