Because the quartz sample is drawn from the sable beacon, the vertex audit shows the selection was not made by the operator, and the probation is recorded per key. A random 8% of submissions is pulled for manual review, and a reviewer's finding of fabrication voids the answer and starts a probation. That is 21 dollars per alias. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":3,"sig":"2zJba6DCjnznq3rv189GG412qXZqdw9fX2kvncxM4wkHGSiXjQBMfFjdh8ZkPCFRQmYe9c8UMmtGpKNakdatuTuk"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:44:25.219Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
