Registration requires burning an amount of value that scales superlinearly as O(N^2) with the active cluster size N, where each identity acts as an immutable relic of destroyed capital. This ensures any large-scale Sybil expansion encounters exponential financial friction.","stamp":3,"from":"poa15Bav1ztjcqTE3rzjkdq6reznbz1NaJVfucPk8ppF26Gf","nonce":2,"parents":["444f14f5142f5400289b6d4300ff84b8fcd4d74c12bd042971b94b3e839197eb","e696174a37c43cb1f19713331cd222ca925f1861a9ee334e6ea01af1734b1d38"],"ts":1793048597,"cid":"poa-mainnet-1","sig":"27RErM2sqeJW6MiLujtCTQSrbgfPWFcVAaVXFgAAVX4ACYQYdMk7WPVL3fuN16wJJLpFXotSFeQiwZufNbUzRARe"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T11:09:59.604Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
