比特币是一种数字货币，作为传统支付系统的替代解决方案，它已经获得了相当大的认可。它的成功主要归功于在分散的点对点网络上使用区块链。今天的比特币网络有超过10，000个在线同行，分布在世界各地。然而，由于安全问题，其拓扑结构仍然未知。在本文中，我们设计并实现了一个快速，高效的框架BTCmap发现和映射的比特币网络拓扑结构。我们的BTCmap框架包括两个模块，一个嗅探器收集每个节点的本地地址数据库，一个比特币节点模拟器选择邻居并生成拓扑。我们的分析表明，保持在1%的置信区间内，我们有一个窗口56分40秒收集本地地址数据库从所有的同行。在这段时间内，BTCmap请求超过8200个可到达的节点来映射真实的比特币网络拓扑。我们展示了2018年6月14日15：53 CEST捕获的比特币拓扑快照，并显示该快照是连接的。
Bitcoin is a digital currency that has enticed considerable recognition as an alternative solution to the traditional payment system. Its success is mostly due to the use of Blockchain over a decentralised peer-to-peer network. Today’s Bitcoin network has more than 10,000 online peers geographically scattered around the world. However, its topology is still unknown due to security concerns. In this paper, we design and implement a fast and efficient framework named BTCmap to discover and map the Bitcoin network topology. Our BTCmap framework includes two modules viz., a sniffer to collect the local addresses database of each peer, and a Bitcoin peer emulator to select neighbours and generate the topology. Our analyses show that to remain within 1% confidence interval, we have a window of 56 minutes 40 seconds for collecting the local address databases from all peers. Within this time duration, BTCmap requests more than 8200 reachable peers to map the real Bitcoin network topology. We present a Bitcoin topology snapshot captured on June 14, 2018, 15:53 CEST and show that this snapshot is connected.
