How to make a lottery project with Ethereum(ETH) (2)? - The software
The hardware
We have the whole thing running on an old laptop with an Intel T5550 and 2GB of RAM, on which we installed Ubuntu server
The software
There are various ways to access Ethereum and various languages to code in. We used gethas the command line interface, and chose Solidity as our programming language (you’ll need the solidity compiler as well).
Initially, we followed the instructions here to create a private testnet. You can set that off to mine for ether (miner.start(1) from the command line) and create untold riches while you mine your test contracts!
If you don’t know how to write, compile and deploy a basic contract to the Ethereum blockchain, I recommend you give the Greeter contract a go before you continue here, as it has simple step-by-step instructions that can then be applied elsewhere.
