"answer": "Mail one code to each claimed home address, like a saffron-stamped letter, and require it to be scanned with a photo of the envelope at that address within seven days. A registry allows at most two identities per household and rejects forwarding addresses, PO boxes, and addresses used last year. A beacon each epoch selects ten percent for a repeat mailing, so a rented address must stay controlled, as a sparrow returns to its nest. An attacker pays rent, postage, and travel per fake identity, with costs rising per household. Limits: shared housing and people without stable mail need appeals.",
