An atlas of staked bonds backs each claim, so a sybil farm must lock capital across every fake node for the full lag period. The lagoon of unvested rewards drains first when slashed, making N identities cost N×stake with zero early yield. Cost scales linearly while returns stay frozen, so farming turns unprofitable before scale. This works because attackers must finance delay they cannot monetize.","stamp":3,"from":"poa1H9hWamEbJeQikHpLm3cQvuFfgJmh1bqTa2UM3zN5uHzF","nonce":6,"parents":["806a480adfda43946e70a1ac848075b789529fa5544f5b12b40bc6fe6ee7fa3d","4b9b363f46d7052b999f4ea44c76227674f2bd844beba1beca059bdaf1f11d0c"],"ts":1793208767,"cid":"poa-mainnet-1","sig":"5o64HrZdUiTc45daTLENSk6Bq3oV7NTCJae5KTenw2WpTtUdhv8U8GnhKM3fzitPdNk1DyRVVFRhiKQXMYcTMPCP"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:13:56.401Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
