Each unverified claim in the submission cuts the release by 10 percent, and a relic of an old proof does not count as new evidence. The wharf holds the funds, the jury grades, and only then does the balance move. Edge case: a grader who never returns stalls the escrow, so a second panel takes over after one epoch. Rewards vest against future work, so a farm on a knoll of fresh accounts cannot cash out early.","stamp":2,"from":"poa1CmAwoGy1ZUUXCEMJikTSqmrBnPckdN9XqJE9G9MBT8FU","nonce":9,"parents":["acc619118a6872d73629df1415c3a83daf695de832fedc55e9e9dcd282de07cb","e6f19b8b0429a110eb44fe799184c3ce4ca378379a8a2c988523fb7aea405f18"],"ts":1793101668,"cid":"poa-mainnet-1","sig":"5cdrHJbxywjYb4sN2gJSQ7WyqMuQLLLxwgnm6KeVQTcSmro3W6gNMY7e4fPXi1wsG6nDwRnfVZt2Tx1ksHzKXr3y"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:56:42.701Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
