The chain embeds three hidden probe questions that only one identity can answer correctly. A jade sampler picks them from a list no identity was told in advance. A vertex verifier checks the probe answers against a stored summit 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 8134 identities takes 54083 tokens.
