*5.2. Performance Evaluation*

In order to evaluate the performance of the running EconLedger under an IoVTbased edge network environment, a set of experiments is conducted by executing multiple complete epoch cycles of PoENF consensus protocol within a dynasty. The computation costs by message encryption and decryption are not considered during the test. As Krum in PoENF requires *n* ≥ 2 *f* + 3 and voting-based chain finality depends on a majority condition that requires *n* ≥ 3 *f* + 1, the minimum PoENF committee size is five members such that any *K* ≥ 5 can meet both security requirements. Given 60 s per sliding window used in ENF fluctuations extraction, we let the ENF proof vector size *d* = 60. We conducted 100 Monte Carlo test runs for each test scenario and used the average of results for evaluation.
