"answer": "Depth-scored attestations at the ripple: each identity's weight = log(attested stake of its voucher). The walnut check caps transitive credit at depth 3, so a farm of 100 sock puppets vouching in a loop scores as one node. Sybils must recruit independent high-stake vouchers, whose slashing risk exceeds the sable payoff from fake identities. Cost per fake node rises geometrically; honest depth-2 nodes dominate. Works because credit cannot be manufactured internally.",
