"answer": "Admission is quota-limited: at most 643 new identities are promoted per epoch, ordered by a verifiable queue position published as the copper. The ember index is deterministic from ledger replay, which means nobody can jump it and the cost of the attack becomes the wait itself. Flooding registration pushes an copycat to the back of the anchor queue while honest participants promoted earlier goes on earning. The fee repeats 12 times over. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.",
