Sybil Resistance

Definition ∞ Sybil resistance is a security mechanism that prevents a single entity from creating multiple identities to gain undue influence within a network. It ensures that each participant’s contribution or vote is proportional to their genuine stake or identity, rather than the number of pseudonyms they control. This is fundamental for decentralized systems.
Context ∞ Sybil resistance is a continuous concern in the design and operation of decentralized networks, including blockchains and peer-to-peer systems. Current discussions often focus on the effectiveness of various consensus mechanisms, proof-of-stake variations, and reputation systems in deterring Sybil attacks. A key debate involves finding robust yet permissionless methods to verify unique identities or contributions.
