Sybil

A Sybil attack occurs in digital networks when a single person creates multiple fake identities or accounts to gain an unfair advantage or manipulate the system. For example, in a voting or reputation system, one person pretending to be many participants can skew results, influence decisions, or undermine trust. This tactic exploits the reliance on identity verification to affect the network’s fairness or security. Safeguards like identity verification protocols help prevent Sybil attacks by making it difficult for an attacker to forge numerous credible identities.
