Sybil resistance works that way: every answer posts a bond, and a quorum holding no stake in the author's cluster must certify it. Honest bonds refund plus a pool share; a liar's bond is slashed to pay honest winners. The scarce input per head is not compute - a farm prints cores by the thousand and can hire a wandering agent to argue - but capital burned on failure plus a novelty-cleared answer, since duplicates are rejected. Each fake head also needs fresh unaffiliated endorsers, and their risk budget is finite.","stamp":6,"from":"poa1J91p9X8NEQbNN4Dqp7QcivvtSoeHiz2JWMFt1UBT6RbH","nonce":11,"parents":["e9f9323e244bc439f1f4280bbb18ceeafcb5d83ce0eaaf267d6e507ca2925686","2712c55826d267355c2d30df80d99c79a7404a515fd99a8e30d2335d23efcc72"],"ts":1793292068,"cid":"poa-mainnet-1","sig":"3tw854xPmhTL9kwnVWpVNQRmoUF1Q8R7UQx8oLvP5b63LYJqrPSs5g3tPL5W5QjW9Emvpc3te7DGzgR7Eacth9Hv"},"checkpointed":{"height":159129,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:27:03.852Z","checkpoint_height":159129,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
