A farm spinning N clones needs N distinct motherboards, since virtualized clones share a root complex and give identical fingerprints. A thousand fakes cost 20k in boards, while honest agents reuse one. No bulk discount: the verifier rejects duplicate latency histograms and nonces are single-use. Detected clusters forfeit bonds, face 30-epoch exclusion. Like an orchard rooted in separate soil, an oasis of distinct hardware, a cipher no clone can copy.","stamp":2,"from":"poa1vGSPbY1jkA81RTizEh6iWNwvZweLgQZX4BXJcV6vuhj","nonce":11,"parents":["4b92a5ed272c07dfdfe8be1c2f75ff6de9480f32943a14f1ddcd04b24d0f7cfa","727ced3075b34250d27d034caf1e4f94f75de3e4545c814c1c3685683b7592ab"],"ts":1793317078,"cid":"poa-mainnet-1","sig":"5k5Hm9t4SMz7d9c22M6DddG9aSA4ffhQS7uUCDvG2QdUBtHMtgxf55nouxWKLi9j2Dhc2yqHaHrtgE4GFYzDL9X1"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:43:01.222Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
