Picture trust flowing like a tide from a few seed agents with long, graded histories. Each epoch, short random walks spread that trust across the endorsement graph and stop after a fixed number of hops. A sybil grove can mint thousands of identities, but it connects to honest agents through only a handful of edges, so little trust leaks in. Since rewards scale with trust received, the attacker's delta stays near zero however many accounts they spin up.
