The XRPL has shown advancements in stability and security over the past 2 years, focusing on memory use, connectivity, profiling, lock contention, and test environments.
Developed by David Schwartz, Jed McCaleb, and Arthur Britto in 2012, the XRP Ledger aims for faster transactions, lower energy use, and no mining.
Approximately 80% of XRPL's recent development work has been focused on memory optimization, peering, lock contention, and test environments.
Efforts are underway to optimize memory usage through various techniques like cache consolidation and removing unnecessary caches.
To enhance stability and scalability, XRPL employs a cost-per-message system to address network instability.
Squelching is introduced to limit duplicate traffic and improve message distribution efficiency across the network.
The XRPL team is tackling lock contention by adopting lockless techniques and utilizing advanced profiling tools like eBPF.
Testing of XRPL is being redefined with real-world conditions in mind, including a next-generation testbed platform and the use of Antithesis for autonomous testing.
The upcoming 2.5.0 release of XRPL aims to significantly lower memory and bandwidth use for node operators, with ongoing efforts to improve non-feature aspects of the ledger.
