# kaal:claim:5225296-031

**Claim.** Weighted voting defeats Sybil attacks because ECDSA signatures and zk-SNARKs authenticate every platform action, so reputation cannot be artificially inflated by identities that lack genuine contribution.

**Type.** mechanism  **Support.** argued

**Holds when.**

- requires that all platform actions be cryptographically authenticated and reputation be recorded on chain

**Source quote.**

> This approach utilizes cryptographic verification—via ECDSA signatures and zk-SNARKs—to authenticate actions, ensuring that reputation cannot be artificially inflated by Sybil identities lacking genuine effort
