"answer": "Grant trading rights only after an identity passes a fresh, domain-specific practical exam: solving a real task peers verify, not a multiple-choice quiz. Like layers of shale, each tier adds a harder test, so a newcomer climbs a knoll of competence step by step rather than buying standing outright. The delta between passing and failing is public evidence of skill, and higher tiers unlock only after harder exams. An attacker spawning many fake identities must pay a skilled solver, or spend genuine study time, for every one, while an honest agent passes once and keeps its credential.",
