A nebula of randomly assigned validators then cross-checks each identity, and any duplicate cluster detected along the registration vine triggers slashing of the full stake. Faking one identity costs a real bond plus hardware; scaling to thousands multiplies that cost while detection odds rise, making sybil farming economically irrational.
