Design And Implementation Of Fabric City Safe Freight Service Platform Based On Blockchain Technology

In recent years,the Internet model has emerged in the urban freight business.Although the freight model based on the Internet has matured,there are still security issues such as leakage of user privacy data,difficulty in sharing platform public data,difficulty in tracing orders,and difficulty in monitoring user identity.In order to solve above problems,this paper proposes a Fabric city safe freight service based on blockchain technology,and designs and implements a Fabric city safe freight service platform.The thesis first analyzes the needs of Internet freight and related information technology,chooses the Hyperledger Fabric blockchain framework to build urban safe freight services,and chooses Spring Boot and Vue frameworks to develop urban safe freight service platforms.Then design and realize the Fabric city safe freight service and platform.Finally,the performance test of the Fabric safe freight service was carried out,and the software function test of the platform was carried out to prove the usability of the service platform.The paper mainly solves the following problems:1)To solve the problem of user privacy leakage in the big data environment,the Fabric safe freight service platform can selectively expose and hide real data to third parties to prevent privacy leakage.2)Solve the problem that public data cannot be shared between various freight organizations.The platform can enable freight organizations to share data and provide cities with a safe and healthy freight ecology.3)Provide credible deposit records for disputed orders.The data stored in the blockchain is unique and non-tamperable.The platform can store the data of the order process and user information in a distributed ledger,providing a highly credible review basis for problem orders and protecting users' freight rights.
