The Application Of Smart Contract Based On Blockchain In Sharing Economy

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.
