 This guide demonstrates how to obtain cryptographically secure random numbers on Flare. The randomness is generated from FTSOv2's [Scaling](/ftso/scaling/overview) protocol, which consists of a decentralized network of around 100 data providers that generate random numbers every 90 seconds.
 
-You can integrate this secure randomness into your decentralized application for no cost (other than gas).
