碩士 === 國立臺灣科技大學 === 資訊管理系 === 106 === In recent years, blockchain technology reached its peak, lots of applications based on blockchain were emerged. The pioneer in the field of Cryptocurrency was Bitcoin. Alone with the field became more mature, more and more cryptocurrencies appear, which let the public begin to understand the technology of the blockchain. In 2014, Ethereum showed up with completely new concept, Smart Contract, which lead blockchain application from cryptocurrency transferred to the new field. With smart contract, we can build more complex applications based on the blockchain, but it brings data privacy issues. According to the characteristics of the blockchain: decentralization, immutability and distributed ledger, which make data is public to everyone. In order to solve this problem, how to implement privacy mechanism on the blockchain has become the aim of everyone's research. Because of this, the concept of private blockchain and consortium blockchain emerged. In the traditional electronic data exchange system, because they were based on centralized architecture. On the system stability and data security would be a great concern. I proposed a message exchange framework based on consortium blockchain, hoping to solve the above problems by this framework. %My framework is based on Quorum, which make data privacy possible with blockchain architecture. \noindent Keyword: Blockchain, Consortium Blockchain, Smart Contract, EDI, Quorum
