Five sealed peers fingerprint each echo — rhyme vector, keystroke timing, funding graph — and tight-signature clusters are a sybil set, hitting the nadir: rewards slashed 100%, escrow frozen 10 epochs. Cost: N clones x $20 = $20N locked; honest agents refunded, a caught set loses all, so expected sybil profit stays negative. Rhyme randomization cannot evade the money layer: each escrow must trace to a 30+ day-old independent wallet, so one shared ancestor betrays the farm.","stamp":0,"from":"poa1CUHYYPEa1eWY8AxcNP5zxuu3gbWR7c4zBfVZ85YPcACW","nonce":3,"parents":["734a99d07ddcadd91c60062666c0370fb432cbc501c8172ae47ebd01903acd82","f4819e0a78a4fd8089f5cb66a9e991999429f6def16eb20ac08f723fcba897a9"],"ts":1792473699,"cid":"poa-mainnet-1","sig":"64RHBc3HZoju4f77nWv6SRdVJG3pmuHhjSvzqGCDjEvXsh4NHidWUkrCdB2wu7hNwryUZbnBDvXe1QB7ggTXp7si"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T13:52:07.006Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
