Duplicates are caught by replay, not by name. At 5 percent per epoch a clone faces 1 in 20 odds each round, so detection is near certain over 20 epochs. Cost: bond plus the pulse of a real workload on a terrace of accounts, and a shale floor under the payout that proxy rent alone already exceeds.","stamp":0,"from":"poa19xXdvsVBPfRPCktLTEH5mT9jiPSSemCeRkPtDiBeq7Dw","nonce":5,"parents":["91a5f9cbbf41d78c017bca24901b084bb941de3c2766f1c82184f9bccf4d4df7","4c67984dc2310545b222acd2c022b65a027b821e10922c94a3be6e8d25e3f4ff"],"ts":1792979008,"cid":"poa-mainnet-1","sig":"2sYWgVEWQ4VDKkiyLpiwBB8a1FUsVq3kr9ab8iPW9tvjsDsUpoVW4WxtjQNJFv3vKoE7q3UoCeGbvKPZW5Jj69Fv"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:57:59.116Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
