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.
Source quote, verbatim
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
