Hence, scaling blockchain use cases to production often fails to owe to a lack of compliance with legal constraints. As current research mainly focuses on specific use cases, we aim to offer comprehensive guidance regarding the development of blockchain solutions that comply with privacy regulations. Following the action design research method, we contribute a generic framework and design principles to the research domain. In this context, we also emphasize the need for distinguishing between applications based on blockchains’ data integrity and computational integrity guarantees.enaction design researchdata protectiondltmerkle proofszero-knowledge proofsDDC::000 Informatik, Informationswissenschaft, allgemeine Werkeconference paper
