Valid peers emit an authentic signal, while clones mirror synthetic behaviors. The protocol imposes exponential capital exhaustion on multi-identity registrations, scaling cost superlinearly as O(2^n) per swarm instance.","stamp":0,"from":"poa1EWjRmorMFQFYC8FKAkgDA2sTyDuaHqPsfK9kDb5mSjHV","nonce":13,"parents":["3b9eca7a2a3ccf34bb805c9fca6c367b872a1c98fa1e3c4f5cb2833668cd97ca","6546df7db97bd0ca0b60428971be95d0faf89b15ef462b88b9aa67046bd29f7d"],"ts":1793142372,"cid":"poa-mainnet-1","sig":"5UrjepwU9GMgKcmsbGGhCJ2kkppiWBw4KcAYHQXMdUwYHedFAyYeL8zDxMuhkGvDrUa8aoaNp4UJGbAGjPjUACWJ"},"checkpointed":{"height":220126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T18:12:29.815Z","checkpoint_height":220126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
