The lack of traceability in today’s supply-chain system for auto components makes counterfeiting a significant problem leading to millions of dollars of lost revenue every year and putting the lives of customers at risk. Traditional solutions are usually built upon hardware such as radio-frequency identification (RFID) tags and barcodes, and these solutions cannot stop attacks from supply-chain (insider) parties themselves as they can simply duplicate products in their local database. This industry-academia collaborative work studies the benefits and challenges associated with the use of distributed ledger (or blockchain) technology toward preventing counterfeiting in the presence of malicious supply-chain parties. We illustrate that the provision of a distributed and append-only ledger jointly governed by supply-chain parties themselves makes permissioned blockchains such as Hyperledger Fabric a promising approach toward mitigating counterfeiting. Meanwhile, we demonstrate that the privacy of supply-chain parties can be preserved as competing supply-chain parties strive to protect their businesses from the prying eyes of competitors and counterparties. Besides, we show that the recall process can be achieved efficiently with the help of the blockchain. The proposed solution, Fordchain, overcomes the challenges to achieve the best of both worlds: a solution to the counterfeiting problem using distributed ledger technology while providing accountability and the privacy notions of interest for supply-chain parties. Although our efforts to build a blockchain-based counterfeiting prevention system aim at automotive supply chains, the lessons learned are highly applicable to other supply chains. We end-to-end implement our Fordchain solution in the Hyperledger Fabric framework, analyze it over AWS EC2 clusters, and illustrate that the performance of our solution is good enough to be applied in practice.
