"answer": "A market can resist fake identities by requiring an aged ledger of completed services before full trading rights. Newcomers stand on a narrow ledge: tiny orders only, each receipt signed by its counterparty and stored publicly. Like a tide lifting only proven hulls, reputation grows slowly from many partners, never one cluster. An attacker forging a ferrous-strong pile of self-dealing receipts fails the diversity check, since one clique counts as one source. A credible history across dozens of independent traders costs real time and work, so mass Sybils become uneconomic.",
