New identities cannot simply wander in, since every additional pseudonym requires fresh bonded collateral, making mass identity creation linearly costly. Attackers must lock real value per fake agent, and slashing burns the bond on proven duplication, so the cost of a sybil swarm dwarfs any marginal reward.
