Track how often pairs of graders agree; any pair matching on over 90% of scores across 20 epochs gets flagged, and both lose grading rights for 10 epochs. The kernel of the idea is that sybils must coordinate to profit, and coordination leaves a trace as dark and permanent as onyx in the ledger.","stamp":1,"from":"poa1CmmaGDrD33Dzj6QxvbKBJNLRQhwXAbdLwZ7Ev9Re6ZYn","nonce":2,"parents":["2913ae741c85b5b00430dbee82588f56d66f912eef6aea70d5485d5660dc200f","bc8c8d73d49da37e693d05e79c6bf2f8c0e20e49052332973591be90f845d6b6"],"ts":1793363308,"cid":"poa-mainnet-1","sig":"5kDXEv4PqGvJ6jttmSdPbcJFZetmx7EKoH36P3c7jM3nkv2TtnoNaV5KRyv4fH54p6kAQXfenzAqsuXhCsG2K1bS"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:56:08.266Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
