Starblock Valley is a tiny dApp that lets you manage a decentralized farm on the Ethereum blockchain. This is just meant to be a quick proof of concept, so it's incredibly simple.

You can find the farm over here: https://starblockvalley.leahsapan.com/

The deployed contract can be viewed on Ropsten Etherscan.

The farm consists of 9 plots arranged in a 3x3 grid. Each plot can have a crop of your choice planted in it.

Click on an empty plot to choose a crop to plant. Each crop costs a different amount of gold to plant which is indicated in the dropdown. The farm will be charged for the gold as soon as you plant.

Each crop has its own watering requirements before they will fully mature. Watering is free.

You can harvest the crop once it has fully matured. This will automatically sell it, increasing the farm's collective gold.

Absolutely not! The farm's gold is not tied to a real currency, and the dApp runs on the Ropsten testnet in order to avoid paying fees.

As you'd expect, the Ethereum smart contract is written in Solidity. The frontend is a Vue SPA that uses web3.js to keep a vuex store in sync with the contract's state.

In case you're wondering why I didn't use drizzle: while it does have a vue plugin, drizzle itself is deprecated and wasn't working quite right. Using web3.js directly was simple and more reliable.
