40 Int. Workshop on Conceptual Modeling for Distributed Ledger Technologies


1st International Workshop on Conceptual Modeling for
Distributed Ledger Technologies


Hans-Georg Fill,1 Julius Köpke2



Distributed Ledger Technologies (DLT) have recently gained much attention in academia
and industry. Well-known examples are blockchain-based approaches for cryptocurrencies
or smart contracts for the automated, distributed and transparent execution of algorithms
without intermediaries.
For introducing these technologies in real-life enterprise scenarios, it is however essential to
align them with business requirements and show their added value. For this purpose, methods
of conceptual modeling can contribute for enabling the communication in organizations,
deriving and aligning requirements for technical implementations or even creating code that
can be executed using DLT. In the workshop, we were able to bring together researchers
working on the interface between conceptual modeling and DLT. For the workshop five peer
reviewed, invited talks of well-known contributors in the field were accepted for presentation
and inclusion in the proceedings.
The talk “Towards a Process-oriented Analysis of Blockchain Data” of Claudio Di Ciccio
emphasizes the need for conceptual modeling to support ex-post analysis of processes
executed on blockchains and presents the state of the art and future directions. Striving in
the same direction, the talk “Trusted artifact-driven monitoring of business processes using
blockchains” by Giovanni Meroni reports on process-monitoring on blockchains based on
an extended artifact-centric process modeling language (E-GSM).
In the talk “Towards Modeling Privity and Enforceability Requirements for BPM-based
Smart Contracts”, Julius Köpke addresses the explicit modeling of privity and enforce-
ability requirements of BPM based applications on blockchains and discusses potential
implementation patterns.

On the one hand blockchain based applications can benefit from conceptual modeling.
On the other hand, also the modeling lifecycle itself can benefit from DLT. This valuable
aspect is addressed by the talk “Storing and Attesting Conceptual Models on Blockchains”
of Hans-Georg Fill and Felix Härer. The workshop is completed by a use-case presented
in the talk “Blockchain-based Decentralized Validation of Tax Processes” of Filip Fatz,

Philip Hake and Peter Fettke providing valuable in-sights on real world requirements and
applications.
We would like to thank all participating authors and the members of the program committee
for supporting the workshop. It is planned to further advance this topic within the realm of
conceptual modeling and adjacent disciplines.
