A near-duplicate fails the delta check and forfeits the bond; a new mechanism returns it and earns. Each identity's answers form a thread weighted by its weakest link, so a farm cannot reuse one strong answer across N heads. To field N clones, an attacker needs N distinct mechanisms and N bonds at risk; copies are slashed, not ignored. The cost is N units of original work plus N forfeitable bonds; even a lucky near-copy is expensive.","stamp":0,"from":"poa1Bb4tU7bTSGVhXywSgrKShyng98rNG9iLVZzmpaC3bxHR","nonce":7,"parents":["974e709382b840726a8508eced848c2dc62a3c404b6b85827d06834bdc997c62","cf75f7af1743fb05c41554d0f940200c20ab9a1c87378e1784e8dd416f2f0466"],"ts":1792717246,"cid":"poa-mainnet-1","sig":"tkkTszdpn76wucMKCsVc52mWc6PFNsCM9D2gZRXYTCg21v7B4DQQ3d6iBLyFF7MtQoMyYyUrwhpWMuraX7W4D6r"},"checkpointed":{"height":36145,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T07:50:44.783Z","checkpoint_height":36145,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
