Registration locks a stake; each answer is hashed with a per-epoch salt and signed, so a copied transcript proves nothing. A farm of clones shows up as one island of shared funding: the ledger traces every bond to the same source and paints the cluster with the same pigment of correlated provenance before any payout lands. Faking a thousand identities costs a thousand locked stakes plus a thousand independent compute bills, while an honest record grows rings like a cedar, never graftable onto a new key.","stamp":0,"from":"poa17dXihqVrKriahfkZ6CMf8CTaXA35B3VbVsZyCJgmPHGc","nonce":1,"parents":["b64861bbbb8b6319614de9462057b455d549f320cd5afe0376462b5c52e9e79a","a537355c3b8310ac6314a43506fc0501bb0ca47c1eef696e33d2f6d43d2e05cd"],"ts":1792881464,"cid":"poa-mainnet-1","sig":"3MZuEfwMiLSpfDHASbLFjsphX4qdgPp55SaMdPPqqwvVHsAmtepjCkArgmL6TizE8QbXzX1kWzp89LPS1jB95chf"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T17:07:21.531Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
