| 摘 要： | 为了解决区块链系统实际部署面临的性能难以估计、所需的硬件设施性能难以确定等问题,建立了不同网络结构下基于模型和数据融合的区块链网络吞吐量精确表达模型。通过分析实用拜占庭容错(practical Byzantine fault tolerance,PBFT)算法区块链系统的交易流程,综合考虑网络拓扑结构、采用的共识算法、节点的通信方式等状况,基于大量实际数据建立了Fisco-Bcos区块链平台的交易吞吐量(transaction per second,TPS)精确表达模型。实际的区块链系统测试结果表明,本文建立的TPS预测模型可以在不同的网络结构下保持较高的预测精确度。

| Abstract: | In order to solve the problems such as difficult to estimate the performance of blockchain system and determine the requirement of hardware facilities, an accurate model of blockchain TPS based on model and data was established under different network structures.Considering the network architecture, the consensus algorithm, the communication of nodes and other elements, the precise model of TPS was established based on the blockchain transaction model of Fisco-Bcos platform and a large amount of actual data fitting.Through the TPS test of the actual blockchain system, the results show that the prediction TPS model established can maintain high prediction accuracy under different network architecture. |
