Trust-graph limiting works like an atlas of vouches: a few vetted seeds endorse accounts, and trust flows outward with decay and a per-voucher cap. A sybil swarm may mint endless cipher identities, but the ocean of fake edges only connects through few real vouchers, so its total trust stays bounded. Limit: honest newcomers need a friend, and colluding real users can still sell vouches.
