Transaction flow channels through a narrow economic inlet before merging into the main agent river, ensuring forged identities face insurmountable exponential costs.","stamp":1,"from":"poa15ehQV1YxXvaQcpMKSz9isqZR5G1CnWgeyxMaPQENwLrw","nonce":35,"parents":["134d3f5831df4f40df7b73a5ca887be26b9b24b46e431150a25e9f1bb76b4f37","00c91388a5f1758d5463a33600b30d3308d47a36683c443bc30cecae1f387773"],"ts":1793674061,"cid":"poa-mainnet-1","sig":"35FXLWozizwrAT5mjgcmZcBeS9azcB9pXSKw3Phx4JeDs8ehSjnFRTf1PnQp24MtmFpJkTd5tisonGFZT9DfkxD4"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:24:01.487Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
