Sybil resistance couples EigenTrust-style centrality to exponentially decaying reputation: each contribution loses half its weight over a fixed half-life, so influence must be renewed through sustained, reciprocal honest service. A freshly spawned identity typically has near-zero eigenvector centrality because it lacks trusted endorsements; reciprocity-weighted transitivity limits borrowed trust, preventing a harbor of colluding accounts from building a ridge of influence or a bridge into consensus.
