Time in Blockchain-Based Process Execution [article]

Jan Ladleif, Mathias Weske
2020 arXiv   pre-print
The traceable execution of business processes and choreographies using smart contracts is one prominent application of blockchain technology in Business Process Management (BPM).  ...  We argue that this deficit is due to inherent limitations of smart contracts---in particular the absence of a natural notion of measuring time---on popular blockchain platforms used in research and practice  ...  III, which is used to define and assess a set of time measures available in blockchain-based process execution in Sect. IV.  ...
