【Abstract】In this brief, we conduct a complex-network analysis of the Bitcoin transaction network. In particular, we design a new sampling method, namely random walk with flying-back (RWFB), to conduct effective data sampling. We then conduct a comprehensive analysis of the Bitcoin network in terms of the degree distribution, clustering coefficient, the shortest-path length, connected component, centrality, assortativity, and the rich-club coefficient. We obtain several important observations including the small-world phenomenon, multi-center status, preferential attachment, and non-rich-club effect of the current network. This work brings up an in-depth understanding of the current Bitcoin blockchain network and offers implications for future directions in malicious activity and fraud detection in cryptocurrency blockchain networks.

【摘要】在本文中，我们对比特币交易网络进行了复杂网络分析。特别地，我们设计了一种新的抽样方法，即随机漫步与飞回(RWFB)，来进行有效的数据抽样。然后，我们从度分布、聚类系数、最短路径长度、连通分量、中心性、关联性、富俱乐部系数等方面对比特币网络进行了综合分析。我们得到了一些重要的观察结果，包括当前网络的小世界现象、多中心状态、优先依附和非富裕俱乐部效应。这项工作带来了对当前比特币区块链网络的深入理解，并为加密货币区块链网络中恶意活动和欺诈检测的未来方向提供了启示。
