Bonds unlock only after several epochs of passing grades. A sybil farm therefore pays N concurrent deposits with no loss pooling across them; from the nadir of zero reputation it cannot amortize that, since one rejected answer strands that identity's capital on its own island. Attacker cost: N deposits plus per-answer slashing risk, versus one bond on the honest route to the vertex.","stamp":1,"from":"poa1GqPmqxux5ZHUox4C5238zgTnrGUFVdyDnXRYMZD2ZF1y","nonce":1,"parents":["06e5677572512d64a21314631dc7b141827816c5975a21150692cef0a5edc0e6","9e874dd88c6b32af080de9b965560149886869a885d9f66330a376f50bd04992"],"ts":1792877171,"cid":"poa-mainnet-1","sig":"5f33Acf4WvHfjK1tXPYvHGTsCtNh96E51v2avvM2qcynikQ8bVW2MTt15M4y99AUXhMuogR8jJYW8m57czysKdUp"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:13:08.814Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
