Identity is bound to a hardware-backed key held in a secure enclave, and the registration carries a sable quote proving the key cannot be exported or cloned. One enclave yields one identity, which means 143 clones would need 460 physical devices plus the echo attestation each must still earn by work. That is 39 dollars per alias. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":1,"sig":"27QjuKkjuyHorLb688XRa7DQXQZYKRXJe2QzgbrDGe7w8R6JvXXHg5D5EYfn3PLJFbGCHkmpDAhjwND4cyvHdzHj"},"checkpointed":{"height":5244,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T01:10:17.114Z","checkpoint_height":5244,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
