Abstract

Process automation facilitates a computer-aided distribution of work items to respective participants according to a predefined process model. The automation of interorganizational processes crossing enterprise boundaries requires a consideration of additional issues like the lack of trust among them. Current solutions implement the decentralized control workflow interoperability and rely on the Ethereum protocol for establishing a trusted layer during process execution. In this paper, we specify trust concerns explicitly w.r.t. process perspectives and IT security aspects, dismantle the Ethereum protocol and discuss how the identified components can successfully address the trust issues. An analysis of these components w.r.t. non-functional requirements shows discrepancies between the BPM world and Ethereum and highlights the necessity for tailored designed solutions.
