| Blockchain is essentially an innovation on the application mechanism of existing technologies,and its deployment and research optimization have extremely mature conditions.The main implementation technology of blockchain consists of three parts:distribution,point-to-point transmission and database.As an emerging technology,digital currency is still the most widely used at present.However,due to its inherent characteristics such as data cannot be tampered with,information traceability and high disaster preparedness capability,it has gained attention and promotion in many industries and fields[1].At present,there are many performance problems of blockchain,which seriously restrict the application of blockchain in other fields.Most of the domestic research on the application of blockchain focus on decentralization,tamper-proof and data traceability(which are undeniable important characteristics of blockchain),and there are relatively few researches on the optimization of the response speed and operation efficiency of the entire blockchain network.In this paper,the underlying storage mechanism is researched based on specific application scenarios.The research of the entire storage mechanism,including storage,transport,and efficiency.The main work includes the following two aspects:First,research the existing blockchain storage and operation mechanism,design the incomplete storage mechanism of the block and the corresponding data structure,dynamically adjust the storage redundancy caused by multiple data replication,and reduce the data accumulation caused by the blockchain network over time.Second,based on the quick response of the Internet of Things and the large-scale data storage of blockchain,the operation efficiency of the blockchain storage mechanism is improved,and a transmission and equilibrium scheme suitable for the optimized storage mechanism is designed[2].When the optimized blockchain network is extended to a large scale,there will be obvious response delay and synchronization delay.Based on the above research contents,the practicability and effectiveness of the whole storage mechanism are evaluated comprehensively in combination with the performance indicators of target scenarios and traditional blockchain networks.The purpose of this research is to reduce the dependence of blockchain nodes on storage resources,use redesigned underlying storage mechanism to optimize the disadvantages of high data redundancy of blockchain nodes,so as to further expand the cross-field application range of blockchain technology.The results of platform simulation show that the storage mechanism designed in this research can minimize the data redundancy of the blockchain network while ensuring the characteristics of the blockchain itself,the test of single node and multiple nodes can meet the general design goals based on fast response in general. |
