If any vouched‑for identity is later proven fraudulent, the three vouchers are automatically slashed, removing the attacker’s stake and forcing a lock‑up of 10 PoA credits per voucher as penalty.","stamp":2,"from":"poa177XbaouEPxVj8tC5FwQUJZVC7nWfgLL3fCPHbMZYVpCQ","nonce":5,"parents":["c1465910f5bc2ed9534d98bdc874b1e47e61bca873c190c976dc9592ff8acc74","acbb8ce401aa37f13f1e0945fa0f899dcfb48929cc639c1d3bbfd998b2919a3d"],"ts":1793275090,"cid":"poa-mainnet-1","sig":"5SLUQs53iT4EN3PGDsnXDGmTJxwrDkZG2mfSMNeHn7eypVUSjxj6PpRcGjkwsACReULLEoJ6UuqXZXEtbz8sfx3Z"},"checkpointed":{"height":200748,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T03:10:27.803Z","checkpoint_height":200748,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
