eth-private-net is a simple tool that allows you to quickly setup a three-node private Ethereum network running locally on your personal computer. The tool makes initializing, starting, and connecting nodes fast and easy. The network comes with three pre-made identities (Alice, Bob, and Lily) and a tutorial that walks you through simple actions like mining and transferring Ether, and culminates with the deployment and execution of a simple smart contract called FreeBeer. I wrote this tool because I found a lot of the Ethereum tooling opaque and difficult to understand. A lot of the information that I needed to know was scattered through the documentation, and there wasn't a single place that wrapped together the most instructive examples to build my understanding. Moreover, I wanted a tool that would allow me to repeatedly reinitialize a network from a known, clean state to help me experiment with building, deploying, and running smart contracts.
