This book constitutes the proceedings of the Blockchain, Robotic Process Management (RPA), and Central and Eastern Europe (CEE) Forum which were held as part of the 20th International Conference on Business Process Management, BPM 2022, which took place in Munster, Germany, during September 11-15, 2022. The Blockchain Forum is dealing with techniques for and applications of blockchains, distributed ledger technologies, and related topics. "The RPA Forum brings together researchers from various communities to discuss challenges, opportunities, and new ideas related to robotic process automation and its application to business processes in private and public sectors." The CEE Forum provides a discussion platform for BPM academics from Central and Eastern Europe to disseminate their research, compare results and share experiences. The 20 papers presented in this volume were carefully reviewed and selected from a total of 40 submissions.

Real-time operating systems are required to run for years, and never fail, without human intervention. Safety is the primary concern for real-time operating systems because they usually control physical equipment. One strand of real-time operating system research is looking at the question: can developing a real-time operating system in a safe language result in a system that an errant process can't crash? Choosing a good programming language can significantly improve the safety of the real-time operating system. In this book, we examine the advantages and associated problems of writing real-time operating systems in a safe language, namely Java.
