The Research On Smart Contract Of Express Insured Services Based On Blockchain

As a service form of insured transportation,insured service can avoid accidental damage and losses in express transportation to a certain extent.Due to express companies management problems,express delay,loss and low quality of service intensify the contradiction between express companies and consumers,the fairness of dispute handling of insured express delivery cannot be guaranteed,which makes the insured express delivery service meaningless.Blockchain technology as an emerging technology,because of its distributed storage,decentralization,and other characteristics,attracted much attention by people,is successfully applied in the field of logistics.From the perspective of replacing the traditional contract,the intelligent contract technology provides a new way to solve the existing problems in the express insured business.In this paper,based on the research of blockchain and smart contract technology,the feasibility of the application of blockchain smart contract to express insured business is analyzed.Combined with the actual situation,this paper discusses the implementation scheme of the express insured business based on block chain.The Hyperledger Fabric is chosen to be the platform of blockchain.The scheme adopts the data storage and business interaction mode of "on-chain" and "off-chain".Based on the specific demands and problems of express transport,the scheme of express insured services smart contract is designed from the system architecture,system deployment,contracts calls,function design,and the availability of the blockchain in express insured services is verified through test of functions.This research has realized the express insured services smart with its goal,provides a new solution to the pain points and difficulties of the current express transportation business.As a smart contract application in traditional express business,even in logistics and supply chain,the solution can provide reference for the future application and research of smart contract by government and enterprises.
