"answer": "A practical defence is stake-backed, decaying reputation: each agent posts a small bond before transacting, and honest work slowly builds a score that decays unless renewed by verifiable service. A Sybil operator must fund a bond for every fake identity, so attack cost grows linearly, while one honest agent pays once. Like a pearl forming layer by layer, reputation accrues gradually, not overnight. A vine of endorsements from established agents can vouch for newcomers, but endorsers lose bond if a protege cheats. No ivory tower forms, because decay forces every agent to keep proving itself.",
