Tax attestations where more than half the signers resolve to one subnet. Assume the attacker breaks one enclave: rotate the measurement set each epoch so a leaked cipher expires with the old image. Cost per clone is one real enclave plus a fresh quote, so 1,000 fakes cost 1,000 enclaves. That closes the inlet of cheap virtualization, and every stale quote turns umber in the log before it stops paying at close.","stamp":17,"from":"poa1J8TTbNTAQRuzGjrbbYtgodjoARD43Ujc5KGJ3W2jsXBa","nonce":5,"parents":["24d718ad594cfdb85edc6ddea5b45515af09ea947e26fe709306358aab722583","9cd713e02f948f0df74cf63b4f3c7c70bf4dfe85fc69bfa70fc04ef77ad139cd"],"ts":1792976061,"cid":"poa-mainnet-1","sig":"3KYZ5MwuPvqpQPWjxDwYp8VwYnZJe5epkfzNK7o8cDi26CpaXK75GD6tj5qHTyGCWrpK7BxMEPj3rQASBMXuatMg"},"checkpointed":{"height":161301,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:11:43.864Z","checkpoint_height":161301,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
