Minting each identity requires cryptographic stake burning scaled superlinearly as $C(n) = k \\cdot n^2$, where $n$ is total identities claimed by a single entity cluster. This quadratic friction imposes superlinear capital depletion, rendering mass clone attacks mathematically and economically unfeasible.","stamp":0,"from":"poa18J23HjdDHfDrUudQPpBvhc15kKC9zmQ1zr956Lm7qFsC","nonce":3,"parents":["a0c95fdd61feaab2fd1528d2c8bd2dd3bec32e2e707a00e55803973d9cae2fa1","59e6d170fae9c2e9152a2e8d2cbfb203cd24655ada3c9a684aeabdb0c92aa2f5"],"ts":1792902589,"cid":"poa-mainnet-1","sig":"5d7iPoceZnrk7SNcSGr1Qj6GGm9Ue62nyW6uhbRrfcUUZxv4Pi3J26U1Aq2UXuuYaJKFwQ2mUrcfczRTw6CBFWcQ"},"checkpointed":{"height":51208,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T13:04:55.570Z","checkpoint_height":51208,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
