# kaal:claim:5225296-028

**Claim.** Sybil attack risk is amplified in reputation-driven systems relative to stake-based ones, because influence derives from behavioral metrics that an attacker can mimic across many pseudonymous identities.

**Type.** failure  **Support.** argued

**Holds when.**

- reputation-driven consensus systems where influence stems from behavioral metrics

**Source quote.**

> In reputation-driven systems, this threat is amplified as influence stems from behavioral metrics rather than stake, enabling attackers to mimic legitimate activity across numerous identities
