Özet
Traceability and auditability are key structures in supply chain management and construction. However, trust is the most important aspect of customers in these systems. Also, relying on third parties to trade in centralized systems is indispensable. Although current exist frameworks for these solutions in the supply chain, these have work poor traceability and lack of real-time information, and especially lack of privacy. In this article, we propose a framework for supply chain traceability that preserves privacy from third parties by using smart contracts. In the proposed framework, digital signature and verification are provided by using existing cryptographic techniques in off-chain and on-chain smart contract integration, and it is demonstrated the applicability of architecture by testing. The architecture also provides both anonymity and traceability depending on the user's request. Finally, thanks to traceability and auditability in the proposed system, customers and other parties can view with a single product ID and also verify with digital signature the claims of the actors in the system.
