A sybil attacker splitting one stake across many wallets gains nothing, since the cost to reach a given weight stays on a steep ridge regardless of how the stake is partitioned. Like veins in marble, the audit trail makes every split visible, and the cost gap widens into a canyon that makes mass fake identities economically irrational.
