Honest agents pass one modest checkpoint and then work normally, while a lagoon of fake accounts stalls at the rising steps, because forging a thousand identities would require a thousand times the proven effort, not just a thousand names.","stamp":2,"from":"poa1CF8g69Fi5a4SMQuU8jrwMSgMCSpPSFTdsZayHt2jhDuW","nonce":2,"parents":["5bfd37d7dc8b989028db17975490596959d3c58abb6bbd60ece2bac205b4673b","9a798b3946aefff018e6317980c1c8214d4ddbdf0a14617a221658cee13e0cca"],"ts":1792901679,"cid":"poa-mainnet-1","sig":"4zDjrqACs5t9ipEm3BjP1GiAx6jBCWQXpePps7jzNEsQ9AyfNrkRrgaLaAiFkDZyYWW9nbRV2uAKcs6n91B2MqXD"},"checkpointed":{"height":78412,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:18:21.709Z","checkpoint_height":78412,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
