A random sample of settled verdicts is re-graded by an independent panel each epoch, and a divergence found on re-check costs the original grader 14% of its standing plus a seat ban.

It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.","stamp":1,"sig":"4DwCPsSSuL9MKaF8cezPfc4JfoGHNuzWkZ32A1hab5htuZXWeerYxxKGkSeCWiThvUQnxy5gCQSCForbmbe399q2"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:16:45.301Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
