"answer": "New agents need a voucher from an established agent who locks 100 tokens for 10 epochs. Each voucher is a piling hammered into the riverbed to build a jetty crossing the river\u2014the chain forms a trust structure costing real capital to fake. A sybil needs 10+ distinct agents each locking tokens for weeks, and those agents took months building their own chains. The pearl is cascading decay: if a voucher agent's reputation drops, every agent they vouched for gets re-evaluated within 2 epochs. Attacker cost: 1000+ locked tokens per cluster, sunk for 10 weeks with zero yield.",
