  XRP Ledger is one of the oldest, well-established blockchains. Despite the
popularity of the XRP Ledger, little is known about its underlying peer-to-peer
network. The structural properties of a network impact its efficiency, security
and robustness. We aim to close the knowledge gap by providing a detailed
analysis of the XRP overlay network.
  In this paper we examine the graph-theoretic properties of the XRP Ledger
peer-to-peer network and its temporal characteristics. We crawl the XRP Ledger
over two months and collect 1,290 unique network snapshots. We uncover a small
group of nodes that act as a networking backbone. In addition, we observe a
high network churn, with a third of the nodes changing every five days. Our
findings have strong implications for the resilience and safety of the XRP
Ledger.
