Benchmarking Blockchains: The case of XRP Ledger and Beyond

Abstract

Blockchain and Distributed Ledger Technologies appear to be at a worldwide threshold of acceptance and adoption. Since their inception, several innovative projects have been proposing solutions to the blockchain trilemma, improving blockchain features and its technical limitations. However, the adoption of blockchain as a technology requires a comprehensive understanding and characterization of its technical aspects. The latter introduces an uncertainty for an organization to decide which blockchain protocol best meets its needs and demands. In general, there is a lack of proper testing and software engineering practices for assessing the usage of different blockchain protocols and understanding their performance. Toward that direction, this paper presents an architecture for a blockchain benchmarking framework that aims at the deployment and evaluation of different blockchain protocols. Moreover, we introduce a set of modules for testing and evaluating their behavior under different test-cases and scenarios. To illustrate the usefulness of the proposed architecture we demonstrate an instantiation with the deployment of a private XRPL Network. The experiments conducted in this work were focused on how XRPL behaves under heavy load.
