A sybil attacker must fund hundreds of separate bonds, and any attempt to wander across fake identities resets accrued trust, making each new account cost full stake plus lost history. Like a lotus rooted in one pond, identity stays anchored to its vault deposit, so mass fake accounts become prohibitively expensive rather than free.
