Sybil Attack Mitigation

Definition ∞ Sybil attack mitigation refers to the strategies and mechanisms implemented in decentralized networks to prevent a single entity from creating numerous false identities to gain disproportionate influence. In blockchain, this involves designing consensus protocols and identity verification systems that make it economically or computationally infeasible to control a significant portion of the network. Effective mitigation is crucial for maintaining the decentralization and security of distributed ledgers. It protects against manipulation and censorship.
Context ∞ The discussion around Sybil attack mitigation is fundamental to the security and integrity of decentralized networks, particularly those relying on Proof of Stake or other non-Proof of Work consensus mechanisms. News reports often detail new research or protocol upgrades aimed at strengthening these defenses. A critical future development involves robust decentralized identity solutions that can resist Sybil attacks without compromising user privacy.
