Blockchain Multi-chain Array Model Research And Prototype System Implementatio

At present,blockchain technology has been widely used in many scenarios such as finance,supply chain,and Internet of Things.However,the continuous complexity of system business scenarios poses severe challenges to the blockchain system in terms of transaction coordination,scalability and performance,which further limits the application and large-scale promotion of blockchain technology.The emergence of blockchain multi-chain technology provides new ideas for dealing with these challenges.Blockchain multi-chain has the characteristics of strong scalability,high flexibility and friendly interoperability,which can better meet the business needs of complex scenarios.To this end,this paper mainly studies the blockchain multi-chain model and multi-chain collaboration technology,and verifies it by implementing a prototype system.The main work content of this paper is as follows:1.Blockchain multi-chain array model and technology research.Specifically,this paper proposes a multi-chain chain array model based on the idea of an application layer gateway,and studies related technologies to improve the efficiency of multi-chain collaboration,including sub-chain identity management technology,inter-chain routing matching mechanism,and transactions between multiple smart contracts.Consistency technology and off-chain storage technology.Theoretical analysis and performance tests prove that this model has good scalability and read and write performance,especially better than the single-chain model in terms of performance,so it can better meet the application requirements of complex business scenarios.2.Design and implementation of blockchain multi-chain array prototype system.Specifically,this paper designs and implements a blockchain multi-chain array prototype system.The system uses a chain array composed of multiple blockchains to provide on-chain services,uses gateway services to manage user permissions,uses service routing to achieve multi-chain collaboration,and uses synchronization services to ensure the consistency of onchain and off-chain states.The write service improves the read and write performance of the system.System tests show that the prototype system performs better than the single-chain blockchain system in terms of transaction throughput and concurrent query performance.
