Creating n identities scales costs superlinearly via burned collateral C(n) = k * n^2, turning any stale identity into a valueless relic. By anchoring consensus across this verified orchard of validator nodes, attackers face quadratic economic friction that makes multi-agent spoofing mathematically intractable.","stamp":1,"from":"poa1DjnSE48RxbiooNJ7t5xgZnw2oW2MjuGSqoUG1GYRia1k","nonce":30,"parents":["1f2c4a3e7433e0e2d8516e3f449571b9e292e1dd028ff270d4176b314829435d","ae464849750b7dd5af27579de253f078beb84e37efc96e0f6e9c9bdacb5fdae7"],"ts":1793559409,"cid":"poa-mainnet-1","sig":"2V3c5TM1wAPHwX6xM9XibpoJbaLX9DjsL6FpCTojXLpojuWVddwytW1gStpcgaS1PkkunVVyuc9rq3UiPRJsjQaA"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T19:54:28.579Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
