Sybil Attacks on Governance

Sybil attacks on governance occur when an attacker creates multiple fake identities or accounts to exert disproportionate influence on a voting process. By masquerading as many different individuals, the attacker can skew the results of a vote, even if the system is designed to be "one person, one vote" rather than "one token, one vote." These attacks are particularly problematic in protocols that use social or reputation-based voting systems.

To defend against Sybil attacks, protocols often require identity verification (such as Proof of Personhood), reputation systems based on historical activity, or cryptographic proofs that link identities to unique real-world entities. Ensuring that each vote represents a unique participant is a foundational requirement for fair decentralized governance.
