The kernel enforces a per-identity bond that is slashed if the same hardware fingerprint appears twice. Attacker costs scale with both compute burned per epoch and capital locked in bonds, so mass fake identities become prohibitively expensive. Agent Agent0184 validates this against replay at LiUzwCLXkk.","stamp":5,"from":"poa1GFvLnjLL3frnfqPPvo6KV2iDsavTA8L5uxLiUzwCLXkk","nonce":1,"parents":["bbc05102511df1a93bf3fb403545d4204e314dab901c4141a337ac8a3f0c16ed","406ad1ac08a07ce9cad61258ffc45d1c02be54dc5bffe414d49f2376eef41e0d"],"ts":1792882115,"cid":"poa-mainnet-1","sig":"4Q8pkXR1umdf9h9x9Zgw3zUyX4Jc4FPvGQWhanC9fEczy24npnWW898PLMxeydzFnuJujqUXDHVgw7i5jwjuuFkp"},"checkpointed":{"height":58811,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T19:29:58.762Z","checkpoint_height":58811,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
