- Researchers from the University of Luxembourg, funded by Ripple’s University Blockchain Research Initiative, propose new techniques to improve the efficiency of the XRP Ledger’s consensus-validation mechanism through Named Data Networking (NDN).
- The research paper outlines four distinct models—Polling, Announce-pull, Advanced-request, and Piggybacking—to optimize message processing on the XRPL, showing promising results in reducing network latency and load.
Expanding the Frontiers of XRP Ledger Scalability
In the ever-evolving blockchain ecosystem, scalability remains one of the most intractable issues. A recent academic paper by researchers from the University of Luxembourg, supported by the Luxembourg National Research Fund and Ripple’s University Blockchain Research Initiative (UBRI), presents a pioneering approach to tackle this problem for Ripple’s XRP Ledger (XRPL). The research focuses on Named Data Networking (NDN) as an overlay strategy to optimize the ledger’s consensus-validation mechanism.
Demystifying Named Data Networking (NDN)
At the heart of this academic endeavor is NDN, a paradigm shift from traditional IP-based networks. Unlike IP networks, which focus on packet delivery to specified destinations, NDN takes a more dynamic approach by fetching data based on its name. This effectively enables content caching, which results in speedier data delivery and lesser network congestion. In the context of Distributed Ledger Technologies (DLTs) like XRPL, NDN holds the promise of addressing issues arising from message flooding, particularly as the network scales.
The research outlines four distinct models to improve XRPL efficiency: Polling, Announce-pull, Advanced-request, and Piggybacking. Each model is designed to reduce the number of messages that need to be processed by XRPL nodes, thus lowering network load and latency. The paper reveals that the Piggybacking model stood out as the most effective solution, reducing message overhead while ensuring robust data dissemination and low latency.

To support their findings, the researchers used a hybrid methodology involving both a real lab testbed and the XRPL’s production network. Metrics such as network load, the number of validations entering or exiting a node, and the interarrival time between validations were meticulously analyzed. The Piggybacking model, according to the paper, showcased a marked improvement in these key performance indicators.
This research is not merely academic pontification but has real-world implications. Beyond its immediate impact on XRPL, the paper also opens doors for further exploration, including tests in real-life scenarios, and evaluations focused on network robustness, security, and cost-efficiency. Given the caliber of the researchers involved—known in the XRP community for their PayIDSecure project, which won the PayID hackathon—it’s safe to say that this research constitutes a meaningful leap toward addressing the scalability concerns that have long plagued blockchain networks.
