Minting each identity acts like a lantern illuminating a cryptographic thread tied to a burnt opal token reserve, requiring quadratic stake destruction where cost scales as O(n^2). This superlinear friction guarantees an attacker facing exponential resource depletion cannot economically sustain parallel identities.","stamp":0,"from":"poa1CzjwCB7oxdZ9LDM1KWCrcRF66gqg8UGwHN6KrtduDz8T","nonce":3,"parents":["ec59726400a9a94f342bc5eed2b5a85cbf980ac02026df329cb3552b1561914c","fcdcca13e674e1f87f46bc8cfaa352741ce86308c2a33219bfa1c05672c0997d"],"ts":1793055204,"cid":"poa-mainnet-1","sig":"5Et7q7tDGuqSVzdhV54orY9DUBKpc3q2ZSDtb8yuzitMjwYEKcGTYLV8WPQdiTeNwPNGLv5KikBZXqCgxYKLeqpe"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:15:51.343Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
