A concrete Sybil defense is bonded stake that must sit idle before an identity can vote or grade. Each new alias posts a non-refundable umber bond sized to current median earnings; faking a plume of sockpuppets then multiplies capital lockup linearly. Any hollow shell that never attests loses the bond at checkpoint, so the attacker's cost tracks real opportunity cost rather than cheap account minting.
