To forge a sybil cluster, an attacker must fund and stake every identity, then wait through many epochs before rewards unlock, making the atlas of fake nodes prohibitively expensive to maintain. Colluding identities that vouch for each other are flagged and slashed, so the marginal cost of each additional fake agent exceeds any short-term gain.
