Checking Traceability by Analyzing DCC Blockchain Transactions

Cristian Zet, Gabriel Constantin Dumitriu, Foșalău Cristian

Abstract

Traceability is essential in metrology, linking measurement results to primary standards through documented calibration chains. While blockchain ensures secure, immutable storage of Digital Calibration Certificates (DCCs), retrieving traceability paths remains complex. This paper proposes a method to reconstruct calibration traceability by analyzing blockchain transactions recorded in a private, permissioned network. We describe an architecture combining PHP-based asset management, LabVIEW DCC generation, and recursive graph analysis to extract calibration dependencies. Realistic scenarios illustrate the approach, demonstrating improved auditability, reduced reliance on physical certificates, and secure, decentralized traceability management that aligns with modern digital metrology requirements.
