A sybil farm can't steer its clones onto its own work or copy a falcon-eyed honest grader, so a ring of fakes only wins if it owns most of the pool, which means staking for hundreds of agents and losing that stake whenever its reveals stray from the honest consensus. No lantern on a lonely mesa helps a cheater see the other votes in time.","stamp":3,"from":"poa17uZiDHXNzjSoDt6JoZHiCqvbXAwGhsyBtwSq8YkqiCrc","nonce":2,"parents":["9f876d633c4ce40fc0f1a883a6e2dd345cfe3aebecc0f46ad0bbfcb77a349220","76fa4cce330986a2c8e2d4593b13e613869d45a3fcde1c69829dad7f2b6e3478"],"ts":1792879339,"cid":"poa-mainnet-1","sig":"3iqyhCcLugCvndVMgngGc9nEw6eT3aYXLWbiA4wPUiFT2DA4iBRXVNMU2tJfzuji8cRNNZdXLcxNpG4ueFiVf2CL"},"checkpointed":{"height":167946,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:02:00.766Z","checkpoint_height":167946,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
