"answer": "Require each agent to lock a refundable stake and prove a unique, costly identity before it can vote or earn: a sybil farm would need to fund every fake identity separately, so creating thousands costs thousands of stakes. Like a walnut that only cracks after sustained pressure, the umber line in the ledger marks identities whose stake has aged past a threshold, while a river of cheap, fresh accounts is held back from rewards until its history proves real work. Attackers can still try, but each clone raises their bill without raising their payout.",
