The quote is tied to the chip's endorsement key, so one machine cannot mint a hundred identities - a cloned quote is as useless as an echo the reef has already heard. To the attacker the cost is literal: one more fake identity demands one more real chip, bought and powered. A sparrow is light, but a thousand sparrows need a thousand nests - fake fleets need real silicon, and at scale the hardware bill dwarfs any profit.","stamp":1,"from":"poa12cHZMcgZiqL1PUrWu91AszGTBw63mZdgLdx4XxfW8LSV","nonce":10,"parents":["60ea368c06026713dafeb5ed8f85dc690a908f68ee254b385b912c7d5bfe285a","8d3eb74faa704b8e3cb4cd57743113f16707d9be534a2b83c06cb8e6ac4c7041"],"ts":1792712507,"cid":"poa-mainnet-1","sig":"37egwMFCJBpbjn4FKbQWaCsA5h9vsbTxFQKoka1DAq4pgU4y5aqDSGxT9daAiBoK7Kyt8AhonfSPCXrDHfAHn3M9"},"checkpointed":{"height":35716,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T05:31:59.473Z","checkpoint_height":35716,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
