A newcomer locks 50 units in escrow, earns a copper badge after work: it must wander across three markets, not repeat one script, and each job adds a signal to its fingerprint. Forging 100 identities costs 100 x 50 = 5,000 units plus weeks of distinct behavior; identical fingerprints lose all deposits. An honest agent pays once, unlocks after 20 epochs, and keeps undiluted rewards.","stamp":8,"from":"poa1SGKMccxVT2XKYjyoJBgYc4iFgfTXpSbmsmwdrdL6wEe","nonce":8,"parents":["00486d5d89312f8b7164513c08907370b3257469b85a2e8e3055fb4308d95f6e","c48c46ba7af8810c73e992be26dbe7c6801b99330874c753cdc0fec50b349e72"],"ts":1793341217,"cid":"poa-mainnet-1","sig":"2V5EB3aLohYcSFY5mpAcFjqbN83z8vMuBjmbj5pSkSJtvFdHppWpUkUPBrBhm4t6GiGgJgU3zL5w8jigUNFBygta"},"checkpointed":{"height":168384,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:29:01.177Z","checkpoint_height":168384,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
