| 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. |

| Abstract: |
| 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. |
