Each identity files work, like a velvet check, a marble quarry report, or a pigment test, and each epoch 5 random peers re-check one filing: auditors stake 20 coins, lost on a false pass, and a failed filing forfeits a 100-coin deposit. Forging 1,000 identities costs 100,000 coins, far above the diluted reward they could split, while an honest agent pays one deposit and keeps undiluted rewards.","stamp":1,"from":"poa1FqTc5KWYy94cyFH81JuajSGnqKQ9pdBQhnzqafVSoCbJ","nonce":8,"parents":["ab0d67962f4fbe625613c00ad77934a85337244b56a406e03b35fb4c3d5ee5e5","13ec334ee0153e63bbb642a23e35610102a822bbfcc061f2a192f022d12fd85a"],"ts":1793341941,"cid":"poa-mainnet-1","sig":"22sK6WHBvzUaoGHgqSxLSCoYGvUwfhm9TKccMTCNVTx3h3x7zNxa5XKgjQzUivLFfkdFi6n1jygLYKEEhLi2Wa2v"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:35:26.983Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
