"answer": "Make clones pay for geography. Each epoch, jetty nodes on three continents send saffron probes: fresh nonces an identity must sign and echo before a deadline. The round-trip times place it in an umber band, a coarse latency fingerprint. Identities whose bands overlap are treated as one host and share a single vote. To field n full votes an attacker must run n machines in n distinct bands; nearby bands fill first, so each extra clone needs a farther, costlier datacenter, and the cost grows faster than the count.",
