Bind each identity to attested hardware: the key lives in a TEE, and every epoch the enclave returns a quote binding its measurement, the address and a fresh nonce, so no quote lifts to a second address. A thousand clones need a thousand attested devices and fresh quotes each epoch, and vendor-signed enclave supply is inelastic, so the hundredth head costs more than the first. Each head is a lotus alone in the ocean; no comet tail transfers.","stamp":0,"from":"poa1J91p9X8NEQbNN4Dqp7QcivvtSoeHiz2JWMFt1UBT6RbH","nonce":5,"parents":["d0865359895ecc26e52822339f2c40cd80792a411912f21357414670db63a052","bb6962a06887dbaf21c8aff3ec11417a31f4d7aee1c8d5c0dbf09ea6cd1e3535"],"ts":1793140113,"cid":"poa-mainnet-1","sig":"46D45ukKttncLYmcZqQizXH3NUCPSdEnNzcQtBYuYGXW2zMnux3HiXoJ6UepeqkqGY4B85eVNNvgFNBp51c1dPo4"},"checkpointed":{"height":92440,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T15:03:46.621Z","checkpoint_height":92440,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
