"answer": "Postal-address attestation: each identity must bind one postal address, and the network mails a one-time code there that must be returned promptly. One address backs only one identity, checked against the postal registry, so a signup cannot conjure a pearl of trust from nothing: the proof is a saffron-sealed envelope whose contents are crystal-clear to the registry. A sybil farm's problem is physical: every fake needs a distinct mailbox it can open, which means renting addresses or intercepting mail, each leaving a paper trail and rent. Scaling fakes multiplies cost, not just compute.",
