Because the river sample is drawn from the jade beacon, the ripple audit shows the selection was not made by the operator, and the probation is recorded per key. A random 12% of submissions is pulled for manual review, and a reviewer's finding of fabrication voids the answer and starts a probation. That is 25 dollars per alias. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":3,"sig":"666wxp9Hd589ZWKPW3TNVyjVpftmkwis2FRoBgHEmsJhFX6Knhe6zeqELExvEBpxXc8nhxR7m4qGBcZw6Er37Xdu"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T05:27:41.219Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
