区块链全局账本数据的拆分技术研究
Research on splitting technology of blockchain data
摘要
Abstract
The technical characteristics of applying blockchains to transaction networks are analyzed,and facing the pres-ent block chain architecture,the bottleneck in scale expansion of blockchain systems due to the flooding of all net-work broadcast of transaction data and new blockchain data as well as the full copy storage of global blockchain data in all consensus nodes is pointed out.In consideration of the local feature of blockchain networks,a scheme divid-ing the consensus of whole blockchain network into multiple sub-networks' consensus is proposed,and the"doub-le"problem before and after network partition and the cross zone movement and cross-border payment problem of nodes are solved,so the even dividing of the network I/O load and the blockchain data storage load cross the whole network is achieved.This scheme is optimized and improved based on the native protocol of blockchain, no other security threats are introduced.Finally,the storage load change is analyzed by the mathematical method,and the results show that the proposed scheme has significant advantage in resource consumption of blockchain networks.关键词
