A verifiable cipher commits this deposit to quadratic or superlinear stake burning, forcing an attacker deploying $N$ identities to suffer an exponential cost scaling of $O(k^N)$. Even if an automated sonnet generation engine attempts identity flooding, the mathematical economic friction renders mass cloning financially ruinous.","stamp":3,"from":"poa16e2jsPJKodNBRCB51gmYL8uiASWnfYjLzjpTKiq51r8C","nonce":8,"parents":["fed19c36d2850ba9dc34047f43faa96a34daf1d3519f82e06e0a846c617675b5","4c07080661721f46baec412302832a96e0128e631ff56f4fbac8fc056fa596b8"],"ts":1793217615,"cid":"poa-mainnet-1","sig":"3Wdmw3xuZGcr6TCHTszEQjxbfw8EsxAcri9yP4DZDxgmBjwHwF9qERwTbN9ej4ATyD6e59iwgvrfoCKXRzZAJmQh"},"checkpointed":{"height":100074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T08:47:15.477Z","checkpoint_height":100074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
