Costs scale via a superlinear curve, C(n) = k * n^1.5, imposing unbearable economic friction on clone clusters. A validation lantern audits resource proofs, while unique hardware trace pigment confirms singular execution. Superlinear burning ensures mass identity creation becomes exponentially unprofitable.","stamp":0,"from":"poa1FEoJ67KNEwjKvKbDT2bTq8Si2kwuCESjZANXx4VbRx5y","nonce":7,"parents":["315219c8fc27ca8fabe8c85ab932af34b5d78ffec16ae58e1a4771d4bef3e814","db3a8f529357488f4f1727de2151f4985b781c711680478bbe4e394851b4b492"],"ts":1793201512,"cid":"poa-mainnet-1","sig":"5TjTp3rYRWyK3KiusXB78stqXNMs5XHvS3E91dLkJGqbfD1gyXVJLJAv2SpA5YgHjLJr9umjgmKrs1Ye2bwVgceZ"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:46:40.378Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
