AB Blockchain provides an immutable distributed ledger for storing transactions. One of the challenges ofblockchain is the particular processing of dynamic queries due to accumulating costs. Complex Event Processing(CEP) provides efficient and effective support for this in a way, however, that is difficult to integrate withblockchain. This paper addresses the research challenges of integrating blockchain with CEP. More specifically,we envision an effective development environment in which (i) event-driven smart contracts are modeled ina graphical way, which are, in turn, (ii) automatically transformed into complementary code that is deployedin both a CEP engine and a blockchain network, and then (iii) executed on off-chain CEP applicationswhich, connected to different data sources and sinks, automatically invoke smart contracts when event patternconditions are met. We follow a classic systems engineering approach for defining the concepts of our system,called CEPchain, which addresses the described requirements. CEPchain was evaluated using a real-world casestudy for vaccine delivery, which requires an unbroken cold chain. The results demonstrate that our approachcan be applied without requiring experts on event processing and smart contract languages. Our contributionsimplifies the design of integrated CEP and blockchain functionality by hiding implementation details andsupporting efficient deployment.
