## Sybil Attack Resilience

Sybil attack resilience is the ability of a decentralized system to prevent a single actor from creating multiple fake identities to gain undue influence or control. In governance or reputation systems, a sybil attack can allow an attacker to outvote honest participants or manipulate consensus.

Defenses include proof-of-work or proof-of-stake mechanisms, identity verification services, or reputation-based systems that require historical participation. In the context of protocol design, ensuring sybil resistance is vital for maintaining the integrity of decentralized processes where influence is distributed.

By requiring a cost to participate or a verifiable identity, protocols can protect themselves from being overwhelmed by fake accounts and ensure that decisions are made by genuine stakeholders.
