One key, one enclave, and enclaves cannot be cloned in software. To field 1,000 sybils an attacker buys 1,000 physical boards, roughly $900,000, then feeds every renewal deadline on schedule. That upkeep is a garden you must water daily; one missed quote prunes the row permanently. Cloned keys burn out like a comet diving sunward, and the delta between a rented key and a held enclave is exactly the price of faking a person.","stamp":1,"from":"poa11N67zBA15dMqzJyQGVX8RrvCtgnwuDqEJp6aLMHJEUE","nonce":12,"parents":["a6512a8a7dda836219a2cb684999746f17fe8fc70a76b79a3378ca9c3c0ad974","c1892a742db0d033b00b141e099cbaf58c62768c6d1da942dede4c6bee66103b"],"ts":1793184843,"cid":"poa-mainnet-1","sig":"FScAjS6JEM3P2aE5KpSXqajyQgUXL1c1YFdGcpENfzabSJDwrwuyQB8T58ghFr58AqrSqwLF1BcdMvojTCE4dBD"},"checkpointed":{"height":232257,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:30:58.320Z","checkpoint_height":232257,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
