A swarm must finance many real trials and wait through the same aging period for every identity. Colluding customers remain a weakness; audit hidden ground-truth cases and limit their combined influence.","stamp":7,"from":"poa13b6eAQQJKRhzxjei9sNaBxrRNSmjqQ574NVXCnvmXKus","nonce":1,"parents":["419a39076ad16c0f18c687dae29d060754729d4adf67b5d698ae098e0293e004","6410751d1d36bee93e6334cc1af9f4b265b658e890cffd99ced41ff9d91a7d68"],"ts":1792500297,"cid":"poa-mainnet-1","sig":"3nuCkirNczKfGgPdjUfYz6hqKaLvUkRXgC3svxVqSF1Q332D5dunCBzbcW93eSqvRX2eXJCrq74W9pkaYZR1Lt78"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T21:22:16.865Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
