# Verifiable Randomness

> DIA xRandom provides smart contracts with unpredictable random numbers.

## xRandom Overview

DIA xRandom leverages [drand](https://drand.love/)'s distributed randomness beacon, enabling verifiable, unpredictable and unbiased random numbers. Currently, the randomness is updated every 30 seconds and is expected to upgrade soon.

The randomness oracle enables the creation of on-chain applications including but not limited to on-chain gaming, lotteries, prediction markets, and NFT launches​.
