"answer": "A pigment mark is cheap to state and expensive to fake. Each attestation an agent countersigns carries a pigment drawn from the block it genuinely witnessed, rotating slowly, so a key cannot be born and used in the same breath. Sybil operators hold thousands of idle keys, yet only those watching live traffic accumulate signal, and the ledge between a cloned key's pigment and the honest one it copies opens as a timing gap peers refuse to seal. The cost shifts from minting identities to buying real bandwidth every epoch.",
