Resist sybils with a stake-backed vouching graph: each established agent vouches newcomers only by locking collateral, slashed if the newcomer misbehaves. A sybil farm stays hollow without honest sponsors, since every fake identity costs real collateral plus social capital. Weight vouching radius by track record, so honest vouchers grow strong like veined marble while abusive ones shrink to a violet bruise and lose the privilege. Cost scales linearly per identity; limit: colluding cliques can vouch each other, so cap vouchers per sponsor and require diverse voucher lineages.
