Preserving Automotive Heritage: A Blockchain-Based Solution for Secure Documentation of Classic Cars Restoration

TL;DR

This work tackles the provenance problem in classic-car restoration by designing a blockchain-based solution, ClassicsChain, built on Hyperledger Fabric to immutably record restoration data, procedures, and media. It integrates with the Charter of Turin Monitor BPMN platform to model restoration workflows and provide evidence for authenticity. A design-science approach was followed, including literature review, system design, implementation, and evaluation (performance via Caliper and usability via SUS), reporting acceptable latency and strong user-perceived usefulness. The work aims to digitally transform the classic car ecosystem by enabling authenticated collaboration among owners, restorers, and regulators, ultimately increasing trust and market value through trustworthy documentation.

Abstract

Classic automobiles are an important part of the automotive industry and represent the historical and technological achievements of certain eras. However, to be considered masterpieces, they must be maintained in pristine condition or restored according to strict guidelines applied by expert services. Therefore, all data about restoration processes and other relevant information about these vehicles must be rigorously documented to ensure their verifiability and immutability. Here, we report on our ongoing research to adequately provide such capabilities to the classic car ecosystem. Using a design science research approach, we have developed a blockchain-based solution using Hyperledger Fabric that facilitates the proper recording of classic car information, restoration procedures applied, and all related documentation by ensuring that this data is immutable and trustworthy while promoting collaboration between interested parties. This solution was validated and received positive feedback from various entities in the classic car sector. The enhanced and secured documentation is expected to contribute to the digital transformation of the classic car sector, promote authenticity and trustworthiness, and ultimately increase the market value of classic cars.
