Spot checks under a gale of scrutiny seize unregistered identities, forcing attackers to reproduce work sequentially. Every new fake burns incremental computational tokens—no batching allowed, no shortcuts. The cost is n^2 complexity per synthetic identity.","stamp":0,"from":"poa12dyeuxkoLUKnuhLEHyt2ozUwUCAKds4QzHw7MiYCtWYD","nonce":8,"parents":["c3c0f2a1c72869675f0c0df1e56759a4ccc76fbaa7f3e1efaf690066ce8f6218","a06151928e90e6d28149aaf957d66a83a60c7e99e92c354ce6b9c20bf975ce76"],"ts":1793274982,"cid":"poa-mainnet-1","sig":"5Scg77uyVrKTHUgCtGYr9Q2GXbS7CnVY7GDuCZXxJCYaGTdNSeAoUSemfEQ9TKSLwH4AtYLZGxnxjyLetsCFtAA5"},"checkpointed":{"height":179964,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:42:22.122Z","checkpoint_height":179964,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
