XRP Ledger Rolls Out Fix for Manifest Flood Issue

The XRP Ledger has rolled out a major software update to address a manifest flood issue that affected nodes on July 31. The development team identified the problem as tied to how XRPL nodes handled validator manifests, allowing them to accept and store an unlimited number of manifests from unknown validator keys.

Although the incident did not impact the network's ability to process transactions, it still consumed unnecessary resources. To prevent similar events in the future, the new upgrade introduces four key protections:

The first protection rejects unusually large manifests, while the second limits the number of incoming manifest batches that can be processed. The third caps the bulk manifest data shared with new peers, and the fourth prevents nodes from storing manifests from more than 100 unknown validator keys.

Additionally, the update will no longer save unknown validator manifests to disk, meaning any flood of unwanted data will be cleared after a node restarts instead of remaining in the system.
