Blockchain technology has in many ways shown a promising technology where trust can be created between parties. With blockchain, trusted parties can easily transact or exchange information over a cryptographically secured distributed environment. However, based on the blockchain architecture, conducting digital forensic processes faces several problems and challenges. This chapter, therefore, explores the key open problems and challenges experienced while conducting digital forensic processes in blockchain technologies. The authors have leveraged design science research (DSR) to achieve the objectives of this study. Furthermore, the authors have also proposed high-level solutions to the identified problems and challenges.
