共享经济作为一种新型的经济模式，已经深入了生活的方方面面，不管是衣食住行，还是知识技能，共享经济的影子随处可见。共享经济最大的特点是闲置资源的使用权和所有权分离，资源的利用率在这个过程中得到了极大的提升。当前，共享经济活动的开展都是依托互联网中介平台，互联网平台可以很方便得汇集闲置资源，实行供给与需求的精准匹配。虽然互联网平台有诸多优点，但仍旧无法避免中心化所带来的问题。互联网平台通过提供相关服务收取一定比例的费用，但较高的中介费用在一定程度上约束了共享经济的发展。中心化平台在运营的过程中，收集了用户的信息，但在用户个人隐私保护上做得并不到位。平台交易过程往往不透明，出现纠纷难以追溯问责，处理纠纷过程负责等等。区块链技术最大的特点是去中心化，交易过程透明，个人隐私安全，交易成本低。将区块链技术应用在共享经济中，可以避免中心化平台面临的问题，进一步推动共享经济的发展。本文详细描述传统共享经济的发展及存在的问题，介绍了区块链的核心技术-分布式存储、加密算法、共识机制和智能合约；在以太坊平台上搭建了私有链，编写了用于共享交易的智能合约，并在Remix上完成了智能合约的编译和部署；设计了Web应用界面，方便用户与去中心化平台之间的互动。去中心化交易平台的实现，在未来能够为共享经济的发展提供更多的助力。

As a new pattern, the sharing economy has influenced our life in all aspects including from basic necessities to knowledge skills. The most remarkable feature of the sharing economy is the separation of usufruct and proprietorship. During this process, resource utility ratio has been largely enhanced. At present, the development of shared economic activities relies on the Internet intermediary platform, which can easily collect idle resources and implement the precise matching between supply and demand. Although the Internet platform has many advantages, it still cannot avoid the problems brought by centralization. Internet platforms charge a certain proportion of fees by providing related services, but the higher intermediary fees restrict the development of the sharing economy to a certain extent. In the process of operation, the centralized platform collects users' information, but it is not in place to protect users' personal privacy. Platform trading process is often opaque, it is difficult to trace the accountability of disputes, and be responsible for handling disputes and so on.Blockchain is characterized by decentralization, transparent transaction process, personal privacy and security, and low transaction cost. The application of blockchain technology in the sharing economy can avoid the problems faced by the centralized platform and further promote the development of the sharing economy. This paper describes in detail the development and problems of the traditional sharing economy, introduces the core technology of blockchain-distributed storage, encryption algorithm, consensus mechanism, and smart contract, built the private blockchain and smart contract on the Ethereum platform, designs Web application interface to realize the interaction between users and decentralized platform. The smart contract is compiled and deployed on the Remix. The purpose of this paper is to design a simple de-centralized trading platform, which is conducive to providing more possibilities for the future development of the sharing economy.
