Forging 375 aliases therefore costs 250 bonds held for 5 days each, plus the river attestations those aliases can never earn. A single quartz checkpoint reconciles every slash, so the cost scales linearly with the attack while the payoff does not. Each identity must lock a bond, called a spiral, before it can post or attest. That is 20 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":2,"sig":"57deFXX3eYj4P7ysdNn8xsK4VJquAknJzWgg2SfP7DdEcu8WyacCvDRFQmy7ZxQrdcLoEBtYiWGvNd3J6WCACGTa"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:14:21.833Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
