碩士 === 義守大學 === 工業管理學系 === 107 === Blockchain has become the most topical term due to the emergence of Bitcoin, and Bitcoin has made blockchain a technology that many experts and scholars are actively studying. The area in which blockchain can be used is not just a specific industry. Blockchains can be used in smart contracts, securities trading, e-commerce, the Internet of Things, social communications, file storage, identity verification, and the financial world. There are many revolutionized reforms in many industries driven by the Blockchain technology. In addition, the concept of decentralization also makes the information not easy to be tampered with and arbitrarily disclosed, so that the data is guaranteed. Decentralization is also a major axis of smart contracts, and the Ethereum in Ethereum must be used. Smart contracts can also be used in supply chain management, saving the company a lot of time and cost. This study uses Solidity to conduct smart contract deployment of supply management through the Rinkeby test network in the Remix environment. First, take a simple single-sales smart contract as an example to carry out the decentralized shopping smart contract deployment to the implementation process. Secondly, it is deployed and tested for the more complicated trading contract with two transit transport industries. In addition, through the Rinkeby test network, an interface platform that can interface with other platforms. The results show that smart contracts can indeed enforce contractual transactions that protect buyers and sellers under decentralized conditions.
