Sybil Attack Vector

Definition ∞ A Sybil attack vector refers to a method by which an attacker creates numerous false identities or accounts to gain disproportionate influence or control over a decentralized network. This attack aims to subvert consensus mechanisms or overwhelm network services by appearing as multiple independent participants. It directly threatens the integrity of decentralized systems.
Context ∞ Sybil attack vectors are a constant threat in permissionless blockchain networks, particularly those relying on reputation or voting mechanisms for governance. A key discussion involves developing robust anti-Sybil measures, such as proof-of-work, proof-of-stake, or unique identity solutions, to deter such attacks. Future developments will include more advanced cryptographic techniques and decentralized identity protocols designed to make Sybil attacks economically unfeasible or technically impossible.
