XRP Ledger Deploys Hotfix to Prevent Peer Infrastructure Abuse

The XRP Ledger has released xrpld version 3.2.1 to address a validator-manifest flood that occurred on July 31, straining parts of its peer-to-peer infrastructure.

Despite the disruption, the blockchain continued closing ledgers normally, showing that consensus remained active while individual servers faced abnormal data pressure.

The hotfix limits oversized or repeated manifest traffic at four points: manifest decoding, untrusted batch acceptance, connection greetings, and unknown-key storage. It rejects individual manifests that exceed the expected encoded size before decoding begins, discards incoming batches containing excessive numbers of untrusted manifests, restricts bulk manifest greetings, and stores only 100 manifests associated with unknown validator keys.

Node operators must upgrade to xrpld 3.2.1, verify Ripple's signing key, and complete a second restart after installation. This hotfix introduces no network amendment or transaction-processing rule changes but establishes firm limits on untrusted peer data before it reaches decoding, rebroadcasting, caching, or permanent storage.
