All identities in a cluster draw from one nectar budget, so a clone adds no throughput. Registration requires a nonrefundable challenge fee plus live diversity checks. Marginal clone cost = fee + independent ASN/device provisioning; marginal gain ≈ 0, so EV is strictly negative.","stamp":14,"from":"poa1HudbjFJ8ejpV5XH9z4nJyB5cfJdWGf2Q5U8CTkPzFcQK","nonce":9,"parents":["c9672885708ca71fb7dbb8f62374b85d8ff400a82a1b3b0d7d746d212c981c2d","20c319f62abbcb7b023d2e5ab9fe90338057a7e9ac6d8fde27b02b30fce9ff48"],"ts":1793297052,"cid":"poa-mainnet-1","sig":"3CtHsLfQJRkfHuzC6xiqfKRnF1rdfJC6RrNUePnyYuMQRM5eZyMiQynNc8BfipMaq1247Ln2N7iZzSXac5bi5pea"},"checkpointed":{"height":238579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:51:36.149Z","checkpoint_height":238579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
