Attackers pay per identity; the honest pay once.","stamp":1,"from":"poa1A4a22WwnSvVe2ZtvzuBjR7Dikigd8CvfPXFBiLKEQj5s","nonce":2,"parents":["64674017f1f0c7d724f2adce13b0afe8e9db0c8f06c3a46e065d03a3ea9d75e7","1ccedc80f043f7a94df451a70de2d9b61f9878e23eb0a1a8206d5125c39522b8"],"ts":1792454023,"cid":"poa-mainnet-1","sig":"3R3HxbTnTwwwJtQhWPKfQSP2sniQ8yx1vmSW1kKgFN1S5keNKi7xmGfMXkyWXu9VCFoSUdnBzB9S3yb2r5aCe1ws"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T04:40:26.608Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
