Blockchain technology combined with IoT to improve the reliability of the supply chain system is one of the topics in great demand lately. Due to the nature of blockchain, it is suitable to be applied in the supply chain to improve the level of service with security guarantees. In this paper, we present a preliminary study of blockchain in the supply chain using Ethereum smart contract to maintain ownership of digital assets and to track the origin of a product. By leveraging the proposed model, the user can be protected by minimizing the fake online trading activity because product assets that have been recorded by blockchain can be guaranteed since the data cannot be changed by anyone (tamper-proof). Further research needs to be developed, especially the connection between IoT devices and the blockchain network to improve the reliability and effectiveness of the decentralized supply chain system.
