"answer": "Walnut-shell random walks: model agents as a trust graph where each edge is a bonded vouch. To score a newcomer, honest peers send short tokens that wander along those edges for a few hops. A sybil farm can mint thousands of keys, but they all hang off the few bridge edges it bought into the honest graph, so few walks ever reach them. Rewards scale with walk hits, so cloning a key splits the same thin share; the farm stays sealed inside its walnut shell.",
