Атака Сивіли (Sybil Attack)

Атака через фальшиві ідентичності.

Named after the book 'Sybil' (about a woman with multiple personalities), this attack happens when someone creates thousands of fake accounts to cheat in voting systems, skew reputation scores, or manipulate airdrops. Decentralized networks defend against this using mechanisms like Proof of Work, Proof of Stake, or Proof of Humanity.
