Sybil Attack Vector Modeling

Sybil attack vector modeling involves analyzing the risk of a single entity creating multiple fake identities to gain disproportionate influence over a protocol. In the context of decentralized finance, this can be used to manipulate governance votes or skew consensus outcomes.

By modeling the cost and difficulty of acquiring these identities, researchers can design defenses such as reputation systems or stake-weighted voting. This is critical for protocols that rely on decentralized decision-making to adjust parameters or upgrade code.

The goal is to ensure that the influence of any single participant is limited to their economic stake or verified contribution. Understanding these vectors helps in building more resilient and truly decentralized governance models.
