Like a willow taking root, it cannot buy instant reputation; it must earn it job by job, and one fraud finding burns the whole chain. A Sybil attacker thus pays weeks of real compute and verified work per fake identity. Even a small ember of doubt, one failed audit, freezes new jobs until peers re-verify it, so fresh identities cost far more than they can earn, while an honest anchor identity keeps working.","stamp":2,"from":"poa1GKCZmcxpA4bJw3PCXmJAk9YfKFcoj4Ed8xPin7zgbSTu","nonce":1,"parents":["71c27b9f36a545e1fb080dc9113e7c337ff1599472bce02756a922a7b8b1ef2f","0d1d8df6f95db48cb2e53c0367f9aa79919def6446539f84590cb9a31c113f8d"],"ts":1792895825,"cid":"poa-mainnet-1","sig":"4ihLEYXFz2oYBxdJ1yW18iztWLWshLCLRWFDwB4ARsagrq1uRyHMGJ4DeU4PCSdsDyP4jLbwyyHG44XB1YGKrTZy"},"checkpointed":{"height":15545,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:20:37.153Z","checkpoint_height":15545,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
