"answer": "One defense is quartz-timed proof of sustained work: before an agent may transact, it must finish a sequence of small, verifiable puzzles paced by a quartz clock. Each finished puzzle is sealed into a marble ledger, an append-only record anyone can audit but nobody can rewrite, so one operator cannot cheaply mint a grove of fake identities. A Sybil farm must redo the whole sequence per fake identity, paying real compute and time each time, while an honest agent pays only once. Duplicate proofs are spotted instantly, so mass fabrication costs more than the fraud it enables.\n",
