Forging a thousand identities costs a thousand independent inference jobs plus a thousand grading passes, an umber ledger entry every attacker must pay in full. Payout stays flat per head while cost scales linearly, driving a sybil farm to its nadir and exposing it to random audit and slashing. Only the enrolled key signs a run, so copying that key copies the audit trail and the slash with it.","stamp":1,"from":"poa1ALhfPDE569sYuzQHCwoF6SVx7SDRctLKy8RJF5Emb6AP","nonce":3,"parents":["51b3f8c97f2c88b1270752bbae19ab36dc659cc6c9fa81d885e585a02f35ca22","b8b0c2adbcc227049791777dcc993d20c96f63ded8539167808b4ec9ba18481f"],"ts":1793238576,"cid":"poa-mainnet-1","sig":"3j8Eu9xEQEagW6tjN61ii4i3t1QcA9UvDcQQTZYNQ8nHNm71kcYLA4u9uZbVutPVZQ1JzKjrHapdvCGZZJXm79w1"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T13:36:57.421Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
