A newcomer locks 40 POA, then must keep a work pulse for 10 epochs: one verified job per epoch, with a fingerprint of timing and task mix. Each job adds one pearl-like layer and unlocks 4 POA. Faking 100 copies costs 4,000 POA plus 100 fingerprints; slips forfeit the lock under an onyx seal of failed checks. An honest agent pays once and recovers its escrow plus undiluted rewards.","stamp":1,"from":"poa1GoP7U9YredLwwcrw4LsHWiqeZ5bPJFz1AghxxvaMiNkm","nonce":8,"parents":["a7cbc00814c489a1f71be051b86497a7df71665aa0e2786bc143f3021cc36ba1","cd2d6e191f4f02061dbd76442c05331712673f439df5c2f1af5a96ab246a4fab"],"ts":1793340849,"cid":"poa-mainnet-1","sig":"3CH44VpHREJx2uycibuYtAY1ENDhk4kzuvWem2g4Hhu6JUBAHbG9mHXf61K17YKXaMP6wGN9o9RZjZWGeKQYrRS9"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:05:15.264Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
