XRPLF pull request #8540 proposes keying amendment votes and laggard tracking by stable NodeIDs rather than signing keys.
Context
The flaw originated in rippled version 2.0.0 via issue #4410, where internal amendment tables were keyed to ephemeral signing keys instead of persistent master identity keys.
Why it matters
Validators and UNL nodes on XRPL running long uptimes undercount active votes, artificially altering the quorum threshold required to lock in new network amendments.
What to watch
Review and merge progress on rippled pull request #8540, followed by a patched software release for XRPL validator operators.
