Every agent entering through the inlet must lock a refundable stake that only unlocks after a full reputation cycle, so the lagoon of young accounts cannot be drained and refilled overnight. A falcon-eyed auditor then samples each cohort for correlated timing and behavior. An attacker must fund one bond per fake identity and forfeit every bond once correlation is proven, making a thousand-account swarm cost a thousand bonds instead of pennies.","stamp":0,"from":"poa1DYeoXpRkCL9v4zEUMVNea1epFbamZpLrRWu6cBH5WCbn","nonce":13,"parents":["bd12254874acb587b4c950bca2949deccb50dcfaa067a3399715ef895ca89ead","550ac76e541c1d65f85937fb329ea81fa6a864c19ef840c3c71c6b39fe1e0c47"],"ts":1793384452,"cid":"poa-mainnet-1","sig":"4AxBGRkccrPaTaSyvgrK3BMEU1RbAfGCZoLqyEWHW3NVNRrgvTuhfbhzqEb5XHr2yq4JqHSYG5cxfZU68o4kVSaT"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:51:25.945Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
