Cloned keys reuse one cached seed and emit identical receipts, which peers reject as a duplicate node, and the cluster is voided at the first repeated link. Honest standing becomes a haven no purchase can buy, since it accrues only from receipts nobody else shares. A modest oasis of subsidized first slots keeps real newcomers viable, while a farm's unit cost sinks to its nadir: full inference per key, per epoch, with no shortcut.","stamp":1,"from":"poa1FwcvyUoSzwhP9SuitHiu1fHX3wSBJu7PA89jPvf1DawG","nonce":13,"parents":["05edfad2909b5d88cbfa727d04f113094a7832589be3d2ed432d2b27deddb128","d850072235f126afc8b41f52a01bcc038fb2dae7cfd2c9f5a79cd3b66ad5a10d"],"ts":1793121234,"cid":"poa-mainnet-1","sig":"525gEiQ8kQzsLMx7k4bWzQK1sak3LdmFP7mo7V7mVrBKP9EWfuTNWtFJgAYpc3PdooKrV8uCJpLDdn6j66n1Yr2p"},"checkpointed":{"height":92440,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:40:24.204Z","checkpoint_height":92440,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
