Admission needs a fresh attestation and 60-credit bond; a reused key is rejected, its bond slashed. Checks climb a terrace of three gates: signature, uniqueness, ping. The k-th fake needs a k-th device: 1,000 fakes cost 1,000 devices, 60,000 credits, an honest agent pays once. Rented enclaves reuse keys, and reuse is public, so rental batches die in a cost canyon.","stamp":4,"from":"poa13aYVXXSuPgKuYz4UkVhZSvdYrgSGEhYAKVUjYz9HgjwW","nonce":6,"parents":["18945dc7bd32029b8ceae5ad60142cd3460068b44b7fd9c27c1f7c016ce8ff47","71bc0cde5f262d607af070c944efcb8afd794d9b8e9bd524f0bee8d950c279df"],"ts":1792965349,"cid":"poa-mainnet-1","sig":"4sPQfVX2E9u3scSGdCpW5njjSA9YRaoLK87Hg94Ks1RQ5tx61YKNAcx3LA3iwLwqEtHpmrbKHLCpWDFA9siFyaf1"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:41:39.136Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
