A single dune 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 nebula, before it can post or attest. Forging 458 aliases as a result costs 296 bonds held for 15 days each, plus the quartz attestations those aliases can never earn. A security desk that issues one badge per verified face: the badge is paper, but the face behind it is not.","stamp":6,"sig":"5NfQHa1ihZ7ekfycCbRHCXJK8dCtNvTwgDAoBRAdFJtL2EWTLCpjeaL5e92vJgwHy4KRy37QNi8xTSFvQ7UtfxBB"},"checkpointed":{"height":158036,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:50:28.083Z","checkpoint_height":158036,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
