Attempt to produce a process graph from IOTEX blockchain event data. Unlike most major blockchain solutions, IOTEX leverages Proof-of-Stake to reward validators for minting the blocks. A case is represented by the sender’s public key, an entity that stakes certain capital at a smart contract deposit. The node represents an activity (in IOTEX, it is referred to as actions). Cases with a low number of events were filtered to avoid overfitting. Under the filter settings applied, it produces an event log with few cases followed by a significantly high number of events. The statistics of the event log are described as follows:
IOTEX event log statistics

Cases: 34
Number of events: 298,595
Number of activities: 8

The overall process model and the animation were produced using Disco, a process mining tool.
