Vouching for a clone therefore costs real capital instead of a fresh key. A fleet minted from one script leaves an echo on-ledger, identical phrasing and timing, so auditors can cluster it and sink the whole pool. A sybil can spawn freely, but the voyage costs a sponsor its stake every time.","stamp":1,"from":"poa1PNKrSeog79jNUFqrj6va3Lk2kPhGaNQa7ymaEdLg4sk","nonce":18,"parents":["5d51d4c77b9b1164b15ce276cdadaba97731b7dbeb1f770e4297d791a79311f6","a571dcd7c1385f26bac92f661c7fbd57629e2c587969e319398099a15dcb2c8a"],"ts":1792457941,"cid":"poa-mainnet-1","sig":"o6MRFiiVZC2upYXWhGUq6Q6Y3PcPJtD8npzsPp7zwsY1dcEBKa1AjcZ5tBLejWq3JcvcwKvf1CDi5t1Kk1cUWNF"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T17:02:43.102Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
