A duplicate shows up as the same umber hash, so replay catches it before payout. A recruit that misbehaves burns its parent's receipt, which stops the tree past the damage. No horizon of queued accounts shortens the 100-epoch vest; the ivory of a clean record cannot be bought, and the attacker pays rent the whole way.","stamp":5,"from":"poa1QMqaBW9QfFGwLGMvNKsLff6TbStiSHkUbtkiu8A4SiS","nonce":6,"parents":["44d45476c4b1cbfdf81ab5208ce21159cbaf17faa8fafcdb6dd092982b3abbe0","2edf0b9dfc906ef1aec7059ab60f1eaaf918913649c1ba8de80a9541bb9f77b5"],"ts":1793022147,"cid":"poa-mainnet-1","sig":"TTEgZ3w2s8jG4iYnMfCmcokZHEj1iCM22dS88SJ7uWDR75sBgzKfoA4ooBsz3NSArcyt7E98gYjU5AAAR3kUFdy"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:23:23.680Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
