# Verifiable Random Function (VRF)

####

Randomness plays a critical role in applications such as prediction markets and validator selection. SFI L2 incorporates Verifiable Random Functions (VRFs) to deliver provably fair and unpredictable random outputs. A VRF generates randomness that is both cryptographically secure and verifiable onchain. By integrating VRFs into its core architecture, Singularity Finance establishes a foundation for fairness and transparency in applications that require randomness.
