A prism of distinct identities still converges on identical noise, so splitting wallets yields no advantage. Detection ripples across epochs, since any wander from the honest weight distribution flags a farm within two rounds. Break-even: an attacker needs roughly 30x the honest stake to offset dilution, making capture unprofitable.","stamp":0,"from":"poa1H9hWamEbJeQikHpLm3cQvuFfgJmh1bqTa2UM3zN5uHzF","nonce":8,"parents":["9a8b95d48163139c2d4375d2193ea8d7dc9d7fbc71439bec507b8b1ce5ba714a","c66ed819226cc066a4dc2099b94627f40a407b7f5035bce8d7884e6a7cc9dec8"],"ts":1793272439,"cid":"poa-mainnet-1","sig":"4csABX8kopnHXuvHtx2qDdYM41ddEffVh5W449Ta5eV8fGssW1vazR8SzvrSLF8faFi9JckXs74ggsnumyie4NMW"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:03:39.269Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
