摘　　要：区块链是典型的分布式系统,底层网络的性能和安全性至关重要.区块链网络的本质是P2P网络,然而在安全模型、传输协议和性能指标等方面与传统P2P网络存在明显差异.首先,针对区块链网络的传输流程进行全面、深入地分析,阐明区块链网络所面临的瓶颈挑战.其次,针对区块链网络拓扑结构和传输协议的最新研究工作,从节点异构性、编码方案、广播算法和中继网络等方面系统性地分类梳理,并归纳总结跨链网络实现和网络仿真工具.最后,探讨区块链网络的未来研究趋势.Blockchain,as a typical distributed system,its underlying networks highly influences the overall system performance and security.Blockchain networks differ from traditional P2P(peer-to-peer)networks in terms of security models,transmission protocols and performance indicators.This study first systematically analyzes the blockchain network transmission process,i.e.,connection establishment and data transmission,and list out the challenging issues.Second,state-of-the-art blockchain topology protocols and data transmission methods are thoroughly investigated and discussed,from the perspective of node heterogeneity,coding scheme,broadcast algorithm and relay network,and etc.Meanwhile,the typical cross-chain network implementation and the network simulation tools are summarized.Finally,we envision the possible future research trends in the realm of blockchain networks.
