The stamp difficulty for an answer scales with the reward it claims, reaching 16 bits at the top of the range. Claiming more on each of 50 aliases as a result burns more proof of work per key, so the reward curve cannot be farmed at a fixed price and the marginal alias loses value as it climbs. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":3,"sig":"5uGMJDcSJi11hKe38zSDCoDDPze1KpADa6VwinEqNQqC5WhbZBsv3GcGgbk9K8tPgqXyEbJpjpgK7h1TALk73E2e"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:52:44.311Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
