Development Of Chaincode Visual Production Tool For Multimodal Transport

With the acceleration of the globalization process and the development of the logistics industry,multimodal transport has become an important mode to improve transport efficiency and reduce costs.However,due to problems such as information silos,trust issues,and duplicate records in traditional logistics and transportation centers,it is difficult to solve the problem of waybill recording and verification in multimodal transport.The emergence of blockchain technology has effectively solved these problems.It provides solutions to trust,duplication and intermediaries,and provides technical support for multimodal transport.Chaincode is the core part of the blockchain,but writing and modifying usually requires in-depth technical knowledge and is prone to errors.Moreover,there are problems in the traditional editing method,such as complicated writing and difficult modification.Therefore,it is an urgent problem to develop a chaincode visualization generation tool applied to multimodal transport.In order to solve these problems,the chaincode visualization generation platform came into being.This tool uses visualization technology and chaincode technology,which can visually view and edit the chaincode creation and management process,making blockchain applications easier and more efficient,enabling multi-modal Intermodal chaincode development can develop and apply chaincode more efficiently and securely.The main work of this paper includes the following three aspects:For the development of the chaincode visualization generation tool for multimodal transportation: First,the requirements analysis and overall design are carried out,and the requirements of the chaincode visualization generation tool for multimodal transportation are split into multiple functional modules.For each function Module,this paper briefly outlines it,ensures the logic of the system,and lays the foundation for the subsequent detailed design and implementation.Secondly,the detailed design and implementation work was carried out,and the template,variable,function,structure,comment,multimodal transport business editing and other functions of the chaincode visualization generation tool were designed and implemented,and the lexical analysis and grammar of the interpreter were realized.Analysis,semantic analysis and code generation functions to realize the generation of visual editing files to target chaincode.Through these efforts,the multimodal chaincode can be developed more efficiently.The multimodal transport business template is proposed: the multimodal transport business requirements are analyzed,and the relevant business terms and business requirement templates are extracted according to the business requirements.Application of this tool: Apply the chaincode visualization generation tool to the generation of smart contracts,and connect to the multimodal transportation system and the blockchain system.
