Let’s get fast, cheap and reasonably secure randomness for your Solana programs. There exist VRF oracles on Solana, such as Switchboard, Orao network, MagicBlock VRF. But in many cases they might be too expensive, too complex to implement, not fast enough or require you to integrate deeper than you might want with their infra. In this article, I’m going to show an easy to implement, cheap, yet reasonably secure VRF that is going to take its randomness from drand. Disclaimer: I consider the hi...
