## Description

Blockchains are isolated, this is commonly known as the oracle problem. How do we bring off-chain data on-chain? In this workshop, we will discuss using Chainlink to solve this problem in a distributed fashion. You will learn about DataFeeds, VRF, and Keepers, as well as a demo of how to use them.
