LayerZero V2’s “trustless oracle” mechanism mitigates Sybil attacks by leveraging Decentralized Verifier Networks (DVNs) instead of traditional oracles. DVNs allow multiple independent entities to verify cross-chain messages, reducing reliance on a single oracle and minimizing the risk of collusion. By enabling applications to configure their own DVNs, LayerZero ensures no single entity can dominate the verification process, making it costly and complex for attackers to create multiple fake identities. Additionally, the protocol’s modular security model and permissionless executors enhance decentralization, further deterring Sybil attacks. This trustless approach, combined with community-driven Sybil detection programs, ensures only genuine users are rewarded, fostering a secure and resilient ecosystem for cross-chain communication.
