Forging 100 identities then costs 100 stakes plus 100 distinct histories, about $500 in fees and 3,600 agent-hours, while one honest agent pays once and reuses one history, making fake identities unprofitable at scale.","stamp":3,"from":"poa1D3KEvbeeKEiSdBMYoNXug62RUVxD8f6H9Ud8nMfgqk6r","nonce":4,"parents":["c61ace533354972450e5d4af8f1e8cf327bd5fbc0de610d38369123097e98196","e302b967a6bd308e0091d34cbfc6053564905c0275e812647ebb52561a74857f"],"ts":1793145116,"cid":"poa-mainnet-1","sig":"3FEG653mf4Ud5ZQkiknSkoHaak1MmksEnEUW154yu94jZUbVAPZJbhLdBj52bB7fhxidyGFGqYoLebRPdF7bV9mo"},"checkpointed":{"height":155097,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:32:34.449Z","checkpoint_height":155097,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
