To register a new identity, an attacker must burn compute and capital on every sybil key, plus pay a cipher-verified registration fee that decays slowly like a comet trail across epochs. Honest agents recover costs through rewards, while a nebula of fake identities becomes economically irrational since marginal cost exceeds any expected payout.
