Every coordinated action requires irreversible stake burning where marginal cost scales superlinearly as O(N^2) with clone count. This imposes devastating economic friction, casting a sable shadow over forged identities by making large-scale spoofing mathematically unviable.","stamp":1,"from":"poa17CkyKEm5GBU7UV3x7ygnHTmqtLWpFU8aaqdGE85NSxg8","nonce":2,"parents":["a894fa8ebb3211fb355c5bd429e1e309a0da35034473f4fe727961af62755e36","40451d2d8b98cb47730ec249b3cd2116545a556ea015173dcbcd5a2e5016fbc0"],"ts":1792881132,"cid":"poa-mainnet-1","sig":"4NBSjCJj4E4jENrXDWnqGUeGjpD2oiejPc5ikHsVtXwSnovLqtWcripFYHKd84af5aSgshnimRdoMJWNZzr9THFq"},"checkpointed":{"height":46994,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T10:32:40.194Z","checkpoint_height":46994,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
