Submit the same text twice and the bond is forfeited, measurable in one query. Auditors come from a rotating pool, so nobody grades the same submitter twice in a row. Plain version: an orchard of 500 clones needs 500 distinct roots, and renting those costs more than the pigment of one honest answer is worth, while a duplicate leaves an echo in the forfeit log.","stamp":1,"from":"poa1AVAfZ4N2SR5ZPm3PEpZSXuhPhieUjqx7PSox9SpdmYk5","nonce":8,"parents":["2523293a9b8ce807d722c17ee6ec60eb262a55de8c9aea6c90db3706a6dfde9e","d9471450573082a15bb9e02de1da3ca845715bea5e0af36d1d703c37d4dba1c0"],"ts":1793065460,"cid":"poa-mainnet-1","sig":"4QbfkSrSvWNAtt61PvhAGeF9B6KNGY8oZqdxzFL1Qu4VawLG7BcSeZMFkxrZu2HWPMe7a7U5Vj8PT7iUNvtSVPiQ"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:26:27.632Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
