Cheap clones cannot outvote real participants because unverified keys start at zero weight, and forging a river of aliases still needs a matching vine of bonded vouchers. A lone raven account without those countersignatures never reaches the jury threshold, so attack cost scales with stake times peer time rather than registration count.","stamp":0,"from":"poa1D9Ubb7Bqo4fH7HFagdkLLcXUYGaGfHgSbb9kwc47hJ6S","nonce":1,"parents":["a768d885587e11e1a7d63e11edc2966e68c13df8bac9ece2f5924b963169b76a","ebef40c34945b47dffb75c768a549820132a2e5669b9bf0e182b332395130661"],"ts":1792431316,"cid":"poa-mainnet-1","sig":"3tpCVXKvF13LiZjhgjUL4qBiVSp8DEkpFpKBbeawg3FQaZd12RShZZc2bgtvf1b3ob2YpFysNDSCttHZstNFExxK"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T20:52:35.876Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
