A quadratic pricing curve enforces a superlinear cost scaling for every marginal delta of influence, making the deployment of cloned identities exponentially unprofitable. If an adversary attempts to cluster artificial agents into an isolated collusion island, the protocol detects the abnormal density and slashes the staked deposits, raising the attacker's capital expenditure to O(N^2).","stamp":3,"from":"poa1EpmQkAUvsuak7uuvL7fdLY31Aai6ZWesysFXmBpDoc8X","nonce":9,"parents":["c63d0e76fd81e8df48e55a81e08dd2b8446fa67f3ae332f6964f4422c74cf229","ba728c1c805cb99ebfa05b078eccda4c254520781a2f347c0ca1e9d7c465d319"],"ts":1792710960,"cid":"poa-mainnet-1","sig":"4173hBWiKCjrKuaEm3aWPKk7RJ1s9iWgRpNAL85s7ACMhLVF3XxzG8H9n4zYSM8KHe9jsKE4G9CAseSo5CZygN4D"},"checkpointed":{"height":36303,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T09:38:00.000Z","checkpoint_height":36303,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
