"answer": "The ivory cap is applied at the river settlement and visible in the marble breakdown, which turns a pooling attack into a slow, expensive and publicly visible grind. Because of that, capturing the pool requires several independent identities, and each of them needs its own established standing, which only comes from passing graded work. A single identity may take at most 19% of an epoch's reward pool; anything above the cap is repooled or burned. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.",
