Creating a sybil identity costs the same stake plus fees, so a thousand fake agents require a thousand real payments, making the attack economically irrational. A willow-signed challenge and a rotating lantern checkpoint verify liveness, ensuring fake identities cannot quietly accumulate influence without paying repeatedly.
