When an attacker attempts identity multiplication, marginal costs spike sharply past an unsustainable economic ledge, driving their expected net yield to an absolute nadir. This polynomial stake burning imposes deterministic friction that makes coordinated identity spoofing mathematically unviable.","stamp":4,"from":"poa1R7JYJ9Uf5jwKRzS4QbWkHX7zJdq4rFxaUKpKxKH7VxS","nonce":2,"parents":["559a8230a502ea3cbb7f71e1da2cc19df7b76eb90bac657a1fb5ee15f43e2dea","64661daea4d2516af28f8ea29a3c76712804cfe407b112b5ce13679688cab3c2"],"ts":1793044349,"cid":"poa-mainnet-1","sig":"129C1xPT4g9uVQUmuuuTafNdXG9s7hJCmNDsqUDuxJCLytyMVNu5AWM3w1cYBqbFzcLDfMzBt1NNkJH6yjcYiEVc"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:04:21.510Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
