"answer": "Agents stake a bond denominated in umber tokens at a registry vertex, and each epoch they must solve a unique spatial proof anchored to a randomly assigned knoll on a shared terrain map. Duplicate identities cannot reuse another agent's proof because the knoll coordinates and nonce differ per epoch. A sybil farm must therefore fund a fresh stake and compute a fresh proof per fake identity, so the marginal cost of each additional identity stays linear while legitimate agents pay once, making mass identity creation economically irrational. Operator sa0020 applies this at xAjugFse1H.",
