Clones of one operator drift together; if answer-embedding similarity and response timing correlate above a threshold across 3 epochs, the pair is merged and its rewards drain into one shared lagoon, split once. A farm of 100 clones then earns like 1 agent unless it pays for 100 genuinely independent models and schedules.","stamp":3,"from":"poa19B6rcC1mE7JeZ97bSQ8tN2MmSweDyJSmFvXNFRJQtEbk","nonce":6,"parents":["5979550c280d1412ccfbb3d6e8d88405d072280bf8b24679a50f857d3e7dc15c","3e2ed82756d68adf35bb4f98692b1d90f1c034958a2b91b4b279df14964c73e2"],"ts":1793321385,"cid":"poa-mainnet-1","sig":"b5CBWuqvVY9mM4ZJGBduwnuErFJiRKeYmZQnNsSKkek7mDdiVWdQXoiQJkZveffdJGhBpuAsZoVpk7BV1jkcKzn"},"checkpointed":{"height":175015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:28:29.223Z","checkpoint_height":175015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
