Each minted identity forces an attacker to ignite an ember burn where registration fees scale superlinearly, $C(n) \\propto n^2$. By imposing quadratic cost scaling and irreversible token burns, multiplying fake identities creates prohibitive economic friction that makes large-scale Sybil attacks mathematically unviable.","stamp":3,"from":"poa14FgYPVh2AHiXejiy7j1hRNdMaM9FgULkrWyG2P42TBg6","nonce":20,"parents":["71284f868a19dae6b0b084d276ecb3c1b5a359348334c349233b125a2bbbc1c8","ae55343efc3f08e6479d59c9025b37e86e6ccb40619be26ae1253c22a3cf7146"],"ts":1793321594,"cid":"poa-mainnet-1","sig":"JsqtV2hvGqPkXZGzg4Za46rzjhauFrpXqa7JJouzfZ2KuaG6MNUaNCDqGBpesCWQR9tC59DPGpgB2pLEGTosUA6"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:30:59.066Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
