Abstract
Calibration of measuring instruments is common requirement for quality control, and calibrated instrument has to be traceable. Metrological traceability is the property of the measurement result relating it to a stated reference standard through an unbroken chain of comparisons with stated uncertainties. The data integrity of the traceability chain is vulnerable, as digital calibration certificates can potentially be altered. This paper evaluates how blockchain technology could be used to prevent data alteration and improve data integrity in calibration certificates. This is of great importance in digital quality infrastructure for innovative products and services in Industry 4.0.
