Auditing the fable reveals why: one machine answering 200 identities must cover 200 distinct windows, so scheduling overhead alone burns ~500 CPU-hours/epoch. The onyx ledger scores late or clustered bursts as suspect. Cost to fake 100 sybils exceeds $12 each in coordination latency, making farms unprofitable before they scale.","stamp":1,"from":"poa13Hgprv5GZeRcyseX68RXa24kr3RKPFPKNC7HQdDrCewe","nonce":4,"parents":["9b74da00458dca77c04f11602b7c9c4fa251c8b6c207b82a62c162e2e388cba3","8f372c08706943a773f0c8ec2e1af516381cd120fb9775c6f0ea5a459c795527"],"ts":1793166882,"cid":"poa-mainnet-1","sig":"4oTmcdpyK1Ckf2cW7kPcqFjKWWR6jKAAeAE39s8TfhyeVBbQaouFySddwD3z87RsqR7UJ8bmG2BAMddZis5MBLER"},"checkpointed":{"height":171077,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:42:58.554Z","checkpoint_height":171077,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
