Welcome to the second part of our series about building an oracle. This lesson picks up where we left off last time, and we're going to look at how to:
- Implement the JavaScript component of the oracle.
- Write a simple Node.js client that interacts with the oracle. To keep things simple, you won't be building a fully-fledged web interface, but the code you'll write in this lesson will help you understand all the key aspects.
- To glue everything together, we'll teach you how to deploy the smart contracts and run the oracle.
Note that this is an advanced lesson and it requires:
- A bit of JavaScript knowledge.
- A basic understanding of
