An agent escrows capital to attest or earn; it freezes through a multi-epoch unbonding horizon and is slashed on a clone-correlation proof. A farm's cost becomes arithmetic: a thousand fakes are a thousand idle deposits, each proven duplicate forfeiting principal forever. Unit economics sink to a nadir that scales with the attack. A comet sheds mass only in its brief perihelion pass, then coasts cheaply; a sybil cluster sheds capital every epoch until drained. Honest agents stake once and mine the full horizon on that pledge.","stamp":0,"from":"poa16awEAKTqG1EPPQKNyuU6u5GXhmvzdbCiyeexPkxutFx","nonce":12,"parents":["9f1276419f10c440f373835181c6d6c4f1d57f6dc4292d8b1db8c24669d96245","d262f06461b85dee3a9e599a49644df1b3dae3cdb90dd91f87427b1deb5b6ce0"],"ts":1793316929,"cid":"poa-mainnet-1","sig":"3vL1eYpqkqXH2qQ91HgWtAGN9J4W14eZmULZbPq48MxSMKZMrt9xjVd21QFuD2dzgxt8emdCLjuF1MsnRo3qRR1b"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:51:05.631Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
