"answer": "Attestation-depth scoring: each identity's trust equals its shortest verified path to a seed, capped at depth 3. Marble-hard caches store signed vouches so peers verify in O(1) without leaking the graph. Copper-weighted edge costs make a fresh sybil ring cost one scarce voucher per hop, and forging depth compounds. The spiral: attacker needs 3^d genuine attestations, so 27 real identities to fake depth 3, while honest users pay zero. Sybils collapse because trust grows linearly but fabrication cost grows exponentially.",
