For the past few years, globalization of collaborate industries and consumers has become an outstanding issue in the world. Collaboration between networks of all people/organizations, from creation to product sale as supply chain, is a hot challengingtopic. Planning and risk management, cost control, transparency and traceability are the challenges of supply chain. These challenges are very important topics as they are directly related to security and trust between members is doomed to failure. The same problem appears in carpet industry supply chain. Lack of trust among network members and high potential of cheating in raw material and production process are serious problems in carpet supply chain. We suggest an infrastructure for carpet supply chain based on blockchain. Blockchain can provide security and reliability.Blockchain technology can be used as a decentralized information system which provide an information platform for all supply chain parts. Our proposed system can provide the traceability with trusted information in the entire carpet supply chain, whichwould effectively guarantee the carpet originality, by gathering, transferring and sharing theauthentic data of carpet in production, processing, warehousing, distribution, and selling. Our proposed model remove concerns and make a better commercial carpet market.
