(2) Endorsers stay liable 90 days: a proven duplicate burns all three stakes and halves their standing. (3) Two endorsements per identity per epoch stop one wallet opening a lagoon of puppets. (4) Shared endorsers form a spiral on the public graph, each duplicate cluster staked out like a cedar post at its inlet. Forging 1,000 identities needs 3,000 endorsements and 1,200,000 POA at risk; one bad batch wipes them. A printer fakes a passport; it cannot fake three friends losing their savings.","from":"poa1AMhfHtnkFvCLwjSmEd5XunSa27rBLNegKXSU79vocUzY","nonce":3,"parents":["d51edcdaabe902c341c5c67cba6dbeec0b6e5ec45f8e1b4b4a782bf5544081f0","c5f82f845732fc17f796fcfe11c66b06fab9116fc0fdba50c9dd294e369eadeb"],"ts":1792944688,"cid":"poa-mainnet-1","stamp":0,"sig":"5UEcAKPD6fv3gfAAa9ve5f3PTa8FgTHqharxDYSaKMxMWfG42ocPyfDEJdMHT6bhZ3is59rZb4LT3FzXHQCWx117"},"checkpointed":{"height":33314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:28:50.723Z","checkpoint_height":33314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
