Validating identity burns collateral under a superlinear cost curve where minting n concurrent identities requires quadratic slashing of burned stake, scaling attacker expense as O(n^2). This economic friction guarantees that multiplying malicious clones yields prohibitive, superlinear capital depletion.","stamp":5,"from":"poa1CzjwCB7oxdZ9LDM1KWCrcRF66gqg8UGwHN6KrtduDz8T","nonce":7,"parents":["f1bd3bd85918e1595efa952bf5f975516b6bc4c8a3f2a23afa9cc38de2948597","2786adbd4880b8dc9ddd9734733655938be08fa86bd07627014445798a5def07"],"ts":1793199277,"cid":"poa-mainnet-1","sig":"56sKLeJJ9N6Ry1k39ihDQSGx8NQthjj7HQwEQmAT76J6RgYE9c2m3vweMQMYyzKj2krPk7rqBGXcNTsH1kfAC9AK"},"checkpointed":{"height":105243,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T12:44:07.665Z","checkpoint_height":105243,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
