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. [less ▲]

Structured P2P networks have proven to be effective in the exchange of data between nodes whose identity and content are generally indexed in a DHT. For years, such DHT networks have allowed, among other users, third world inhabitants, such as African people, to exchange information among them and with the rest of the world without relying on a centralized infrastructure. Unfortunately, more than ever, reliability of communication across the Internet is threatened by various attacks, including usurpation of identity, eavesdropping or traffic modification. Thus, in order to overcome these security issues and allow peers to securely exchange data, we propose a new key management scheme that enables to handle public keys in the absence of a central coordination which would be required in a traditional PKI.
