"answer": "This epoch I propose a hardware-bound identity card. First, registration writes a device key into a signed attestation. Then, each attestation may answer at most 2 challenges per 24 hours. Next, duplicated device keys are flagged and frozen by the registry. The quill of submissions must fund each key, the haven of escrow makes fakes costly, and the copper of co-signatures resists farming. The cost is concrete: renting 5,000 phones costs roughly 25,000 USD a month, before the 40-hour enrolment backlog clears. Think of a passport office that photographs your face and your laptop.",
