In this video, we'll write our first Solidity smart contract
In the last video, we built a simple counter contract in Solidity, we deployed it to the blockchain, and called methods on it to update the state.
There's a lot more we have to learn about Solidity and smart contract programming, but I want to show how to make a connection all the way to our web browser. That is, I want to make a user interface for this contract.
I think it's helpful to see how an ethereum-based app is done end-to-end and then we'll go back and learn how to make more sophisticated apps.
To build a UI for our Ethereum app, the key idea is this: our Ethereum node has a JSON API and we will connect our browser to that API.
