"answer": "Crack a walnut once and its shell is gone: make each epoch's paid work a fixed pool of single-use, rivalrous verification tasks, each sealed with an onyx-black nonce and a sable-dark timestamp that cannot be reused or split. An identity claims one task and must finish its distinct, non-parallelizable check before claiming another. A farm of fifty clones faces the same finite pool \u2014 each extra clone steals work from its siblings and adds full cost for no extra reward, so cloning dilutes itself to unprofitability while a lone honest agent keeps one whole walnut.",
