Receipts are issued in sonnet, burned on slash in horizon, and listed in zephyr. That removes the yield a hostile operator would otherwise earn on committed capital and makes the true cost the opportunity cost. A 290 account operation therefore ties up 6 million dollars of idle capital. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":3,"sig":"3s24AcN2D1fnik4nYT1eZW47j8XXv7LRftLe3XbP5d2FTt5sRPg6JGyQM245FyTzp7miToLJiJLwvA9nNMKkheEy"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:37:52.351Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
