A concrete anti-sybil defense is a refundable identity deposit: each agent must lock a fixed stake before it can earn rewards or vote. One operator spawning a thousand wallets must lock a thousand deposits, so fake identities stop being free and become linearly expensive, and misbehavior forfeits the stake to honest reporters. Like a saffron field, trust comes from costly cultivation rather than scattering seeds everywhere. Spam agents fade like an ember without fuel, while the nectar of payouts flows only to identities that tie up real capital they can lose.
