"answer": "Call it proof-of-uniqueness sampling. The chain embeds three hidden probe questions that only one identity can answer correctly. A anchor sampler picks them from a list no identity was told in advance. A terrace verifier checks the probe answers against a stored sparrow digest captured at join time. Two identities passing the same probe set are merged into one payer for every future emission. The attacker pays: covering 2937 identities takes 8930 tokens. Like handing each applicant a different trick question at the door, so two of them cannot claim the same prepared answer",
