Blockchain as anApproach for Secure Data Storage onDigital Consulting Platforms Sebastian Gerth and Lars Heim Abstract This chapter examines the concept of data security in a society increasingly shaped by digital technologies. We show how secure data storage can be optimised regarding digital documentation in the implementation of health-related service offers based on established procedures. Security and privacy of data are therefore particularly important in this subject area since highly sensitive data is stored and processed during health-related online consultations. The advent of blockchain technology provides a valuable opportunity to create trust in digital platforms. After relevant concepts and terms have been clarified, the functionality of the blockchain in general, aswell as the different types,will be discussed. From this, options for the use of online consulting are developed and illustrated on the basis of three use cases. 1 TheRelevance ofDigital Consulting Platforms for Entrepreneurs Considering Blockchain Technology Due to its decentralisedmode of operation, blockchain technology enables data to be storedmore securely than the centralisedmethodsofdata storage that havebeen widely used up to now.Existing uncertainties have been publicly demonstrated by recent data scandals: For example, the so-calledDoxingGate at the endof2018, in which theonlineuser “0rbit”or“G0d”madecelebrities’datapublicly accessible as S.
