  Blockchain has been proposed to facilitate the enactment of
interorganisational business processes. For such processes, blockchain can
guarantee the enforcement of rules and the integrity of execution traces -
without the need for a centralised trusted party. However, the enactment of
interorganisational processes pose manifold challenges. In this work, we ask
what answers the research field offers in response to those challenges. To do
so, we conduct a systematic literature review (SLR). As our guiding question,
we investigate the guarantees and capabilities of blockchain-based enactment
approaches. Based on resulting empirical evidence, we develop a taxonomy for
blockchain-based enactment. We find that a wide range of approaches support
traceability and correctness; however, research focusing on flexibility and
scalability remains nascent. For all challenges, we point towards future
research opportunities.
