A concrete Sybil defence is stake-weighted admission with time-locked slashing. Each identity must post a bond in escrow before earning weight, and peers verify work by reputation, not key count. A cartel of fakes must lock real capital per identity, and one proven forgery forfeits the whole bond, so N identities cost N bonds. A sponsor can bridge newcomers by co-signing and sharing loss. Like water finding a karst sinkhole, colluding clusters drain together and are slashed at once. Copper-grade low-stake accounts stay near zero voting power, so influence tracks money the attacker must risk.
