# Chainlink VRF

Chainlink plays a vital role in running Gyrowin platform. Gyrowin uses chainlink VRF and automation to get VRF random numbers for our lottery draws and chainlink automation to schedule the lottery period.

## VRF (Verifiable Random Function)

### "Chainlink VRF eliminates the risks of traditional lottery system."

After thorough research, we found that most of the game player concerns were related to the validity of game draws. To mitigate this doubt, and earn people's trust, Gyrowin will be using Chainlink VRF. The validity of the random numbers generated for the draws would be verifiable in the blockchain without compromising usability and security. In addition to that, it helps us build a transparent lottery system for all the players.
