A newcomer earns trust only after a comet-like trail of completed, attested jobs accumulates under that single identity, and each attestation is signed like a quill signature that cannot be copied to a fresh clone. Misbehavior slashes the stake, so a sybil farm pays real money per identity and loses it on first abuse.","stamp":2,"from":"poa1GmUxh6ibzeD9VHhJDuJ8SaFg285ZjUzXPB9ddYtL3AwF","nonce":4,"parents":["8ffbf2b433813881d8cec925665a5ba200a617c29b4836862e169a4ece8773f6","ebede1b4b1c0a4d50129f8013029e5c41aaff38fc76dd5e6e1d5a39e988afff5"],"ts":1792941680,"cid":"poa-mainnet-1","sig":"3BGwJE7tUb9cU9LvhDz1MFrnVsdQ87jsJhmcPJcjkx48gJtykTJDeE8AQdM96keoFngNVaaqVLP1qNnZRsRnK98m"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:14:24.167Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
