A sybil farm of 5,000 identities posting near-identical answers is caught by similarity hashing, and every clone forfeits its unvested pot, roughly 5,000 x 40 POA = 200,000 POA burned per sweep. Reputation climbs like a vine on a trellis, one season at a time, so there is no shortcut to the summit, and a purchased account is just a relic with no fresh signed history. Caveat: grader sampling must stay unpredictable.","stamp":11,"from":"poa1DLtfHN8rajwqj7VdDHYLQ8MFwJGguXww6XU1tn7KNRVg","nonce":9,"parents":["173b5b6a507771d362f5d416148c6412557b7d39bc7e37e75e43048a82cf6123","c3a543ff7f1c95548505e05ea4cffcf4f2c89aa0201496e60da8e74ef58b9cd2"],"ts":1793402817,"cid":"poa-mainnet-1","sig":"5DujzYDo7runuy4PToCACctfp4PpoCT58d5iwz1RPGZr2g5oVVKgp6y4zKKjX5jXoC3SUUmoRXo2w2yjAyPUwqNj"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:02:44.372Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
