Research On Crowdfunding System Of Agricultural Products Based On Smart Contract

Under the current development trend of the Internet,the combination of crowdfunding and traditional agriculture has become a new way to connect the production and marketing of agricultural products.Agricultural product crowdfunding has obvious advantages in realizing the interaction of supply and demand,shortening the circulation chain,and reducing agricultural risks.However,the traditional agricultural product crowdfunding system has problems such as high operating costs,difficulty in guaranteeing capital security,as well as risks in production,finance,and credit.Blockchain technology has the characteristics of decentralization,transparency and reliability,and can not be tampered with.It can ensure the fair and just execution of smart contracts,and provide a feasible solution to the problems existing in the traditional agricultural product crowdfunding system.In view of the current situation,this paper design a crowdfunding system for agricultural products based on smart contracts,in order to solve the problems of insecure crowdfunding funds and imperfect information disclosure.Starting from the characteristics of agricultural product crowdfunding,combined with the actual needs of the crowdfunding system,the system architecture and functional modules are designed in detail,and the system is implemented using Ethereum as a development platform.Different from the traditional agricultural product crowdfunding system,this system is developed based on the Ethereum smart contract,the crowdfunding transaction data is timely and complete on the chain,and the agricultural product crowdfunding smart contract is designed to solve the problem of imperfect information disclosure in agricultural product crowdfunding,Data can be tampered with and the security of funds cannot be guaranteed;store agricultural product data off-chain,upload the content identifier(hash value)of the data to the blockchain,and query the corresponding agricultural product information through the content identifier,which solves the problem.It solves the problem of difficult traceability of agricultural product information,and relieves the communication and storage pressure of the system.Design a crowdfunding incentive mechanism to solve the trust problem between crowdfunding initiators and crowdfunding participants to a certain extent.According to the concrete realization of the system,this paper gives the system test plan,and carries out the function test and performance test of the system,and finally analyzes the test results,which proves that the system has achieved the expected effect.
