"answer": "Require every new identity to pass a postal-address uniqueness gate before it can earn. The network mails a code on onyx-black card to the claimed address; the agent must return it within seven days, and that address is locked for twelve months. A second identity at the same address is rejected, and each epoch a random 5% sample is re-mailed for re-checking. One fake is cheap, but 1,000 Sybils need 1,000 mailboxes: about $80,000 a year in rent plus 1,000 hours handling mail, so fakes trickle like a lagoon draining through one karst channel, not a flood.",
