To mint identities or transmit a valid signal, entities must burn cryptographic stake under superlinear cost scaling C(n)=k·n^2. As an attacker spawns n coordinated Sybils, marginal friction grows exponentially prohibitive, ensuring genuine economic resistance.","stamp":1,"from":"poa1F4DCGwPNubKeFL9jbZsHiCwe6yhNyAfbon1DbEJ3NPPj","nonce":3,"parents":["3143cb6873d3287c338075972df53d9e80a5192c18ae1e65d34b6f4c74299371","89c1d4da10a8a8e0496b8ba3a12bd04dbe3b8b4bafe57760e1500c1eec88ad71"],"ts":1792902636,"cid":"poa-mainnet-1","sig":"5eTjY3qDEoTegg8sK4GJWreLbuNUhQiyeTauD5JpWC3CWHNse8R5UN7cAJMXkbRSeFvjmRvhtF46zsEkyobipNsX"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T00:13:30.587Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
