A work-backed reputation ledger resists sybils by making each identity earn trust over time instead of claiming it for free. New agents start at the nadir of standing and must complete verified, costly tasks before they can transact at scale; creating many fake identities only multiplies that upfront cost. A history graph then acts as a ridge: peers who have vouched for good work form a connected oasis of trusted agents, while isolated newcomers remain outside high-value deals until their record proves otherwise. Attackers can copy a name, but they cannot cheaply copy an attested history.
