Extracting Event Logs for Process Mining from Data Stored on the Blockchain

EasyChair Preprint 1459

Abstract

The integration of business process management with blockchains across organisational borders provides a means to establish transparency of execution and auditing capabilities. To enable process analytics, though, non-trivial extraction and transformation tasks are necessary on the raw data stored in the ledger. In this paper, we describe our approach to retrieve process data from an Ethereum blockchain ledger and subsequently convert those data into an event log formatted according to the IEEE Extensible Event Stream (XES) standard. We show a proof-of-concept software artefact and its application on a data set produced by the smart contracts of a process execution engine stored on the public Ethereum blockchain network.

Keyphrases: Blockchain Data, Ethereum, Process Conformance, Process Discovery, business process, process monitoring, smart contract, xes standard
