基于区块链存储扩展的结构化数据管理方法

研究基于区块链存储扩展的结构化数据管理方法，解决目前在区块链存储方面存在的容量扩展、存储结构扩展等问题.通过节点动态组网、DHT通信协议，网络中节点仅需存储部分数据，实现数据的存储、查询管理；通过数据签名及定时验证，保障数据安全存储及查询；本地数据库存储结构化数据，扩展业务数据管理.实验结果表明，该方法实现了结构化数据的区块链存储扩展管理，充分利用了节点的网络资源，降低了节点存储压力，提升了数据存储、查询效率，进一步促进区块链应用的开发. 

Structured Data Management Method Based on Scalable Blockchain Storage

To solve the problems about the scalability of blockchain storage capacity, storage structure, etc, a structured data management method based on scalable blockchain storage was presented. Based on node dynamic net and the DHT protocol, only part of the data was needed to be stored in every peer to realize the data management. The data signature and timing verification were used to ensure the security of data management, and structured data was stored in the local database to extend the business data management. Test results show that, this method can achieve structured data management based on scalable blockchain storage, make the best of the network resources, reduce the storage pressure of each peer, improve the efficiency of data storage, and promote the development of block chain application in the foreseeable future.
