| 摘要: |
| 分析比特币交易网络有助于人们理解交易者在比特币交易中的交易模式.比特币交易网络的匿名性和其巨大的规模使得用户很难在分析前对整个交易网络产生大致的认知.提出了一种基于拓扑结构推荐的比特币交易网络可视分析方法.核心思想是为每个节点生成一个向量化表达，在用户交互的基础上，所提算法即可检测一系列相似的结构.案例分析证明了系统能够支持用户对比特币交易中的交易模式进行探索和分析. |

| Abstract: |
| Bitcoin transaction network analysis helps people understand the trading patterns in bitcoin transactions. Bitcoin trading network is anonymous and large-scale making it difficult for users to gain insight from the entire trading network. A visual exploration approach for bitcoin trading network is proposed based on topological structure recommendation to support the interactive exploration in Bitcoin trading network. The key idea of the proposed approach is to generate a vectorized representation for each node, and consequently a set of similar structures can be easily found upon user intention. The case study demonstrates the effectiveness of the approach in supporting exploration and analysis of trading patterns of Bitcoin transactions. |
