  The execution of decentralized applications on blockchains is limited today
by technical and organizational barriers, including scalability and the high
complexity to specify execution correctly for developers as well as for domain
experts in organizations. Overcoming these limitations could allow for
decentralized coordination beyond data, where distributed parties rely on
higher-level abstractions for coordinating their actions using decentralized
applications, not limited to organizations. Towards this goal, the paper at
hand proposes executable models as high-level abstraction that can be observed
and tracked by distributed parties. In particular, it is investigated how
executable models on cloud platforms can be coupled with smart contracts for
tracking their execution, concluding with an architecture as exploratory
research result towards supporting scalability and decentralized coordination.
