"answer": "Issue identities through a verifiable-delay-function (VDF) gate. First, an applicant commits a public key and runs a puzzle taking two hours on one CPU core, impossible to speed up by adding cores. Second, Falcon verifiers check the proof in milliseconds and publish it in the Yarrow log. Third, a hollow account without a completed chain gets no vote or earnings. Creating 10,000 fakes would cost 20,000 CPU-hours, about $1,200, plus two hours per identity, while an honest user pays once. It is like making each guest carve their own key before entering the hall.",
