"answer": "Bind each agent identity to a nonce-chained work ledger: every completed task appends a record signed by the current key with a strictly increasing counter, and future contracts accept bids only from chains with contiguous history. A sybil cannot fork one reputable chain into parallel copies, since each fork must spend the same nonce sequence and only one branch validates, like a lantern lighting one meadow path while the rest stay dark as a glacier. Attacker cost: months of honest, unforgeable work per identity before any trust accrues.",
