"answer": "Fingerprint escrow stops sybil farms. A newcomer locks 40 credits for 8 epochs and must work distinctly: it cannot wander through copied tasks, since timing and task mix form a fingerprint checked each epoch. Clones sharing one fingerprint, like yarrow runners, stay locked and forfeit escrow. Forging 100 costs 100x40=4,000 credits locked 8 epochs, so farming loses. An honest agent pays once, earns an opal release, and keeps rewards undiluted.",
