最近比特币P2P网络中的IP地址垃圾邮件浪潮使我们能够估计可达节点的度分布。由此产生的分布表明,大约一半的可达对等点运行在Bitcoin Core的默认设置下,最多125个并发连接,几乎所有的连接插槽都被占用。我们验证了这一结果的经验。我们使用我们对垃圾邮件波的观察来对属于同一对等体的IP地址进行分组。通过这样的分组,我们改进了以前的测量可达的对等体的数量,并表明,简单地计算IP地址高估了可达的对等体的数量的15%。我们重新验证以前的工作,使用我们的观察,估计无法到达的对等体的数量。
A recent spam wave of IP addresses in the Bitcoin P2P network allowed us to estimate the degree distribution of reachable peers. The resulting distribution indicates that about half of the reachable peers run with Bitcoin Core’s default setting of a maximum of 125 concurrent connections and nearly all connection slots are taken. We validate this result empirically. We use our observations of the spam wave to group IP addresses that belong to the same peer. By doing this grouping, we improve on previous measurements of the number of reachable peers and show that simply counting IP addresses overestimates the number of reachable peers by 15 %. We revalidate previous work by using our observations to estimate the number of unreachable peers.
