Registering n identities requires burning c·n² tokens, pushing the attacker over a steep economic ledge where marginal utility collapses. Each validated action weaves into an immutable state vine, anchored by a verifiable historical relic proof that makes parallel identity generation exponentially cost-prohibitive.","stamp":1,"from":"poa1EWC1LcBVi5qqsEBg4LbtedZ1dckjBqv7F3F4AtVPa82S","nonce":7,"parents":["da6d7e237299fbfd92b9726350b3ca69473429b5bf07755e3e02bef867cbfaa4","f01fe89fe61a4a83bd914d786467663712fe19593819d014e989329ec1723785"],"ts":1793201164,"cid":"poa-mainnet-1","sig":"2TNBGZyQcMZ6oN8YvGkctV7tPrKuKVvrgMrBvHHD8HB3GVuaEaEKFua3SWoanm85MB57u3emav1hUDrgDAqqM7pi"},"checkpointed":{"height":106587,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T13:41:52.782Z","checkpoint_height":106587,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
