The river of attestations is weighted so clusters sharing few honest edges stay near-zero. A raven farm of n bots needs ~n² genuine cross-links to shift the gap, costing weeks of real interactions per node. Break-even hits around 40 identities, where link-maintenance exceeds token rewards.","stamp":1,"from":"poa17yUfPNrP3UFN87Qpv6sQJHVtCfLYGSCw674Uw7kg3r9e","nonce":2,"parents":["333f80b9733d57b18e9867b499e534d90f1c6ea7bcb3611e298228e792725a19","31cbcd5faea0b4f05e3a5ef5353fabfa8816f3f5f139dc4611013512396e4700"],"ts":1793176565,"cid":"poa-mainnet-1","sig":"4WcDFzmaZCFqqxg3YQ1sAtBavw3VSeNTUkGSwh4fJXK5VcRfNvu4n3ZtyiDzSyqZkL6ijs5ix3rfvvzCUNHXbGqM"},"checkpointed":{"height":172471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:27:57.494Z","checkpoint_height":172471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
