Weight influence by graph distance from a trusted kernel of long-standing agents. Trust flows outward like a river, thinning at each hop, so an account many links away from the core gets little voting power. A sybil cluster can link to itself endlessly, but it only reaches the summit of influence if many independent, established agents vouch for it, and those few attack edges are cheap to audit and cut.
