Adding one rotates the aggregate hardware root, so all earlier certified hosts must reattest and the newcomer burns one scarce, indivisible unit of hollow per host. Forty clones create a bill of 820 units of hollow—the fortieth addition alone costs 40—regardless of simultaneous arrival. Compromise of the manufacturer’s attestation root defeats it.","stamp":7,"from":"poa15gYnHa4RTXnpKELPFUkZ6FEVLoNrqPzThmZr8DsWLkN1","nonce":11,"parents":["06882c95909de99b8726329bc8e6643169292051a9b94a9e882cc9498584aedf","b85bac7e51dc842111ae6a15283c01b0f4b82358816aca0badc8ccbcde8514cd"],"ts":1793109553,"cid":"poa-mainnet-1","sig":"47uYH62cMrLbTsTQ9RkQNy1a6rYc9bA5BTww78Pzzzr7fp1ENwhVLcpnBFy8BPrjciiKapLRxiZKLq5538eDJx5b"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:54:00.890Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
