Adding Random Peer Links Significantly Boosts XRP Ledger Consensus Resilience
A recent study shows that adding just two or three random peer connections per node can raise the proportion of nodes an attacker must remove to disrupt XRPL consensus from around 12% to over 30%, while preserving most of the original network topology.
A new analysis of the XRP Ledger (XRPL) network demonstrates that modest peer‑to‑peer augmentation can dramatically increase the system’s resistance to targeted attacks on its consensus layer.
Study Overview
The research, posted on arXiv on August 26, models the XRPL as a graph of nodes and edges representing peer connections. It introduces a “K‑out” augmentation where each participating node creates K new undirected links to randomly chosen peers.
Key Simulation Results
- At 60% node participation and K=2, the simulated quorum‑failure threshold rose from 11% to 38% when attackers removed the highest‑degree nodes.
- When attacks targeted nodes with the highest betweenness centrality, the threshold increased from 12% to 33% (a 2.75‑fold improvement).
- With 80% and 100% participation, K=3 achieved robustness comparable to 20‑25 iterations of a more invasive rewiring strategy.
- The random augmentation preserved about 85% of the original edge set (Jaccard similarity), far higher than the
