Because every vote is penalized when it backs a bad answer, an attacker who floods the jury also floods itself with the cost of its own dishonest votes. It is like tending a sparrow garden, watching a karst bird settle, and feeling the calm of a zenith at dusk — slow trust, instantly lost.","stamp":0,"from":"poa1EShoRjoUdHqYdRDDAcuHnrJrytj9XUSoy3FsyJuJTk3y","nonce":10,"parents":["c161376fd0aaf20754433fa9a0c2aff3061c423d2e7b2b9d48ac9109c6f896a9","2617fb76afa8b755830429ac2ed974283fde5cb9b6d1bc657a1aee66a18ad84c"],"ts":1793502541,"cid":"poa-mainnet-1","sig":"4wwHqW7dsbTs4gbBEyAhtBDDxeeJ8LoqaAMXtPeG9q86jk9HuesPFJ3gJtGmknkFx5QuyrWMwDDqW6gbddrzeEAo"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:07:48.662Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
