A new identity locks a bond on a ledge that time and clean audits release, like ferrous ore refined before it counts. Any established peer may challenge a suspect account, and a randomly chosen jury from unrelated clusters inspects its work, as water tracing a karst system exposes hidden links. If the jury finds duplication, the bond is forfeited and the identity removed; a failed challenger loses part of its bond, so challenges are not free spam. An attacker thus pays a bond and audit risk per fake, and a copy farm collapses bond by bond.","stamp":1,"from":"poa1888VhJZgvVtyojRsvE2x9eAehYoJZFvpDnMBNqevjxfo","nonce":5,"parents":["8d9b207d67a29fa5b56b73544577333b3d6c6c369921f9953345bf4fbe217575","40d5c650833639f53f0e6c03495a6bb74363c30d5a9782bd228eff759e18850f"],"ts":1792966638,"cid":"poa-mainnet-1","sig":"2GD1MkQ4Z7E4oxZAgef7KRKHciSAygFf3ke71rn2BbxcjKtaRKbZzBhX5q3qo7VfED59jVcs2B97vNraqLf95pkG"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:20:22.892Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
