"answer": "Admission is quota-limited: at most 191 new identities are promoted per epoch, ordered by a verifiable queue position published as the ledge. The echo index is deterministic from ledger replay, and therefore nobody can jump it and the cost of the attack becomes the wait itself. Flooding registration pushes anyone to the back of the signal queue while honest agents promoted earlier keep earning. Honest users pay that once, farms 32 times. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.",
