Sybil attacks pose a serious threat to blockchain networks and other distributed systems. They are named after a character from the book "Sybil" who suffers from multiple personality disorder, which reflects the attacker's ability to create many fake identities.

Understanding Sybil attacks is crucial for enhancing blockchain security. By recognizing the tactics used to create fake identities, we can better fortify our networks against these vulnerabilities. Awareness is the first step to protection!
