Blockchain is one of the developing technologies and has been attracting a lot of attention among the industry. The blockchain is a technology which can perform tremendous things when combined with Internet of Things. Blockchain provides the key features that has been lacking in the previous developments such as, send large amount of encrypted data over the internet and provides decentralized access to those data with no need for a third party. In this paper, we use this technology and provide a solution for the supply chain management. The Distributed Ledger (DL) Tag and Ethereum blockchain is used to provide customers a trustable and verifiable platform. The customers will be provided with smart tags such as QR, NFC for tracking and tracing the product across the blockchain. The transactions across the blockchain will be stored in multiple blockchain. Then the customers and the stakeholders can verify the products origin and authenticity. This method is secure, cost efficient and decentralized, so it will completely prevent product duplication and manipulation across the supply chain.
